Power Logger Before You Start 7 Magnet Hanger Kit The accessory shown in Figure 3 is used to: • Hang the Logger with power supply attached (use two magnets) • Hang the Logger separately (use two magnets) • Hang the power supply separately (use one magnet) Voltage Test Leads Voltage test leads are four-core, flat, test leads that do not tangle and can be installed in tight spaces. On installations where the access to Neutral is out of reach with the three-phase test lead, use the black test lead to extend the Neutral lead. For single phase measurements use the red and black test leads. hcf058.eps Figure 3. Magnet Hanger Kit
1736/1738 Users Manual 8 Thin-Flexi Current Probe The Thin-Flexi Current Probe works on the Rogowski coil (R-coil) principle that is a toroid of wire used to measure an alternating current through a wire encircled by the toroid. See Figure 4. hcf028.eps Figure 4. R-Coil Operation Principle The R-coil has many advantages over other types of current transformers: • It is not a closed loop. The second terminal is passed back through the center of the toroid core (commonly a plastic or rubber tube) and connected along the first terminal. This allows the coil to be open-ended, flexible, and able to be wrapped around a live conductor without disturbing it. • It has an air core rather than an iron core. It has a low inductance and can respond to fast-changing currents. • Because it has no iron core to saturate, it is highly linear even when subjected to large currents, such as those used in electric power transmission or pulsed-power applications. A correctly formed R-coil, with equally spaced windings, is largely immune to electromagnetic interference. i(t)v(t)Ar10 k R3330 k R110 nF C1LF347UI:A1GND21143 VinVout
Power Logger Before You Start 9 Use the color clips for easy identification of the four current probes. Apply the clips that are appropriate for your local wiring codes on both ends of the current probe cable. See Figure 5. hcf025.eps Figure 5. Test Leads with Color Coding Kensington Lock A Kensington Security Slot (also called a K-Slot or Kensington lock) is part of a built-in anti-theft system. It is a small, metal-reinforced, oval hole found on the right side of the Logger (see item 6 in Table 3). It is used for attaching a lock-and-cable apparatus. The lock is secured in place with a key or combination lock attached to a plastic-cover metal cable. The end of the cable has a small loop that allows the cable to be looped around a permanent object, such as a cabinet door, to secure it in place. This lock is available from most electronics and computer suppliers.

Power Logger Storage 11 Storage When not in use, keep the Logger in the protective storage bag/case. The bag/case has sufficient space for the Logger and all the accessories. If the Logger is stored for an extended period of time or is not in use for a long time, you should charge the battery at least once every six months. Tilt Stand The power supply includes a tilt stand. When used, the tilt stand positions the display at a good angle for use on a tabletop surface. To use, attach the power supply to the Logger and open the tilt stand. Power Supply The Logger includes a removable power supply, see Figure 6. The power supply is either attached to the Logger or used externally with a dc power cable. The configuration with the externally connected power supply is preferred in locations where the Logger with the power supply attached is too big to fit in a cabinet between the door and panel. When the power supply is connected with the Logger and connected to line power, it: • converts line power to dc power and is used directly by the Logger • automatically turns on the Logger and continuously powers the Logger from the external source (after initial power on, the power button turns on and turns off the Logger) • recharges the battery The power cord/measurement line cover slides to select the input source.  Warning To prevent possible electrical shock, fire, or personal injury, do not use the power supply if the mains power cable/measurement line slide-cover is missing. hcf031.eps Figure 6. Power Supply and Battery
1736/1738 Users Manual 12 How to Charge Battery The Logger also operates on an internal rechargeable Lithium-ion battery. After you unpack and inspect the Logger, fully charge the battery before first use. Afterwards, charge the battery when the battery icon on the screen indicates that power is low. The battery automatically charges when the Logger is connected to the mains power. The Logger continues to charge when turned off and connected to mains power. Note The battery charge is faster when the Logger is turned off. To charge the battery: 1. Connect the mains cord to the ac input socket on the power supply. 2. Fit the power supply to the Logger or use the dc power cord to connect the power supply to the Logger. 3. Connect to mains power.  Caution To prevent damage to the Product: • Do not leave batteries unused for extended periods of time, either in the product or in storage. • When a battery has not been used for six months, check the charge status and charge the battery as appropriate. • Clean battery packs and contacts with a clean, dry cloth. • Battery packs must be charged before use. • After extended storage, it can be necessary to charge and discharge a battery pack to obtain maximum performance. • Dispose properly. Note • Li-ion batteries keep a charge longer if stored at room temperature. • The clock resets when the battery is completely discharged. • When the Logger shuts off because of low battery, enough battery capacity is available to back up the real-time clock for up to 2 months.

Harmonics Spectrum Relative to Harmonic Limits This feature is available on 1738 or 1736 with 1736/Upgrade on installation of the IEEE 519/Report license. The screen shows the harmonics relative to the individual limit defined by a user-selected standard. The standard is selected in the Measurement Configuration. Each bar is green when the measurement is below the individual limit for this harmonic or THD, otherwise, the bar turns red. The number of displayed harmonics varies in accordance with the selected standard. Note This screen provides quick feedback about the harmonic levels compared to Power Quality standards. It is no proof of compliance to the standard. The average calculation interval of 1 second is much more frequent compared to the 10 minutes required by applicable standards. A limit violation in this screen does not necessarily result in a standards violation. For example, when the measurement values surpass the maximum allowed tolerance during a short time period. Use the feature to record data in logging sessions and perform standard compliance measurements. For more information about how to start a logging session, see page 32. The side menu in the harmonics screens has dual use. First, select the parameter to display and confirm with . The selector bar jumps to the lower section for the phase selection. The number of available phases and the Neutral current depends on the selected topology. Refer to Measurement Configuration for details. Make your choice and confirm again with . Some screens do not include  (Show Menu) to access the side menu. Use the cursor keys instead. Measurement Configuration Use the Change Configuration touch button to access the measurement configuration screen. The configuration screen allows you to change the parameters for: • Study type • Topology • Nominal voltage • Current range • Scale factors for external PTs or CTs • Auxiliary input configuration • Review the voltage event limits • Configure the inrush current limit • Select the standard for harmonics compliance assessment (available on 1738 or 1736 with 1736/Upgrade or IEEE 519/Report license) Use  to navigate between the sub-screens.
Power Logger Function Selection Buttons 21 Study Type Depending on the application, select either Load Study or Energy Study. • Energy Study: Select this study type when voltage measurements for a power quality assessment and power and energy values that include active power (W) and PF are required. • Load Study: For convenience, some applications require you to measure only the current that makes the connection to the point to measure. Typical applications are: - Verify the circuit capacity before adding additional load. - Identify situations where the allowable load can be exceeded. Optionally, a nominal voltage can be configured to get pseudo-apparent power readings. Power Quality Select the power quality standard (available on 1738 or 1736 with 1736/Upgrade or IEEE 519/Report license) for compliance evaluation. EN 50160: voltage characteristics of electricity supplied by public distribution networks. The Logger supports these parameters: • Frequency • Voltage Variations • Voltage Harmonics and Voltage THD • Unbalance • Events IEEE 519: recommended practice and requirements for harmonic control in electric power systems. The standard defines limits for voltage harmonics, voltage THD, current harmonics and TDD (total demand distortion). The limits for current harmonics and TDD depend on the ratio of maximum demand load current IL to the short circuit current ISC. Set the values with  and . Note If the values of ISC and IL are not currently available, you can update these values at a later time with the Energy Analyze Plus software. Set the Harmonics Standard to off when the harmonics compliance evaluation is not required.

1736/1738 Users Manual 28 Nominal Voltage Select a nominal voltage from the list. If a voltage is not shown in the list, enter a custom voltage. On energy studies, the nominal voltage is required to determine the limits for dips, swells, and interruptions. The nominal voltage on load studies is used to calculate the pseudo apparent power: nominal voltage × measured current Set the nominal voltage to off if the apparent power readings are not required. Voltage Ratio (only in energy studies) Configure a ratio factor for the voltage inputs when a potential transformer (PT) is in series with the voltage connections such as when you want to monitor a medium-voltage network. The default value is 1:1. Nominal Frequency Set the nominal frequency to be the same as the power line frequency, 50 Hz or 60 Hz. Use  (Show Menu) to navigate between the sub-screens. Current Range Configure the current range of the attached sensor. Three ranges are available: • Auto • Low Range • High Range When set to Auto, the current range is set automatically and depends on the measured current. Low Range is 1/10 of the nominal range of the attached current sensor. For example, the low range of an iFlex1500-12 is 150 A. High Range is the nominal range of the attached current sensor. For example, 1500 A is the nominal range on an iFlex1500-12. Note Set the current range to Auto when you are not sure about the maximum current during the logging session. A specific application can require you to set the current range to a fixed range rather than Auto. This can occur because the Auto range is not gapless and may lose too much information in the case of a highly fluctuating current. Current Ratio Configure a ratio factor for the current sensors when a current transducer (CT) is used to measure the much higher level on the primary side at a substation or step-down transformer that has a built-in metering current transformer. The current ratio can be used to increase the sensitivity of the iFlex sensor. Wrap the iFlex sensor around the primary conductor, for example 2X, and enter a ratio factor of 1:2 to get correct readings. The default value is 1:1.
Power Logger Function Selection Buttons 29 Auxiliary Input 1/2 Configure the Auxiliary input to show the readings for the attached sensor. In addition to the default setting of ±10 V, up to five custom sensors can be configured and selected for the Auxiliary input channels. To configure custom sensors: 1. Select one of the five custom sensors. 2. When the sensor has not been configured, push  (Edit) to access the configuration screen. 3. Configure name, sensor type, unit, gain and offset. Confirm the settings with  (Back). 4. Select the sensor for the Auxiliary input with . The configuration includes name, sensor type, unit, gain and offset: • Change the Name from Custom1...5 to any clear identification of the sensor with up to 16 characters. • Select the Sensor Type from a list that includes 0-1 V, 0-10 V, 4-20 mA, and other. Use the 0-1 V and 0-10 V settings for sensors with a voltage output directly connected to the Aux input. The commonly used sensors that provide an output current of 4-20 mA can be used. In this case, an external resistor parallel to the Aux input (+) and Aux input (-) is required. A resistor value of 50 Ω is recommended. Resistor values >500 Ω are not supported. The resistor value is entered in the sensor configuration dialog and is a convenient method for configuration of the sensor measurement range. • Use up to 8 characters to configure the measurement Unit of the parameter. • Configure the gain and offset in two ways. For sensor types 0-1 V, 0-10 V, and 4-20 mA, the Gain and Offset are automatically calculated with the measurement range of the sensor. In the Minimum field, enter the measurement value that the sensor supplies on the output, 0 V for 0-1 V and 0-10 V sensors or 4 mA for 4-20 mA sensors. In the Maximum field, enter the measurement value when the sensor supplies 1 V for 1 V sensors, 10 V for 10 V sensors, or 20 mA for 20 mA sensors. For all other sensors types, use Other. For this sensor type use a gain and offset. Example 1: Temperature sensor ABC123 Measurement range: -30 °C to 70 °C Output: 0-10 V The configuration for this sensor looks like this: - Name: Change the name from Custom1 to ABC123 (°C) - Sensor Type: Select 0-10 V - Unit: Change Unit1 to °C - Minimum: Enter -30 - Maximum: Enter 70
1736/1738 Users Manual 30 Example 2: Fluke 80TK Thermocouple Module Output: 0.1 V/°C, 0.1 V/°FSettings in sensor configuration: - Sensor type: Other - Unit: °C or °F - Gain: 1000 °C/V or 1000 °F/V - Offset: 0 °C or 0 °F Events The Events screen shows the settings for: • Dip • Swell • Interruption • Inrush Current The Dip, Swell, and Interruption settings on this screen are information only, but you can edit the Inrush Current setting: 1. Highlight Inrush Current. 2. Push  to open a numeric keypad. 3. Use the cursor keys to input a new limit value. Connection Verification and Correction Once the measurement is configured and the voltage and current inputs are connected to the system under test, go back to the Meter mode and use the Verify Connection touch button to confirm the connection. The verification detects: • Too low signal • Phase rotation for voltage and current • Inverted current probes • Wrong phase map In the connection verification screen: 1. Push  to toggle between generator and motor mode. Usually the current flow direction is toward the load. Use Motor Mode for these applications. Use the Generator Mode when the current sensors are connected intentionally to the generator (for example, during the time energy goes into the grid from regenerative braking system of an elevator or on-site wind turbines). The current flow arrow indicates the correct flow: a normal condition is shown in Motor Mode with a black arrow pointing upwards, in Generator Mode the black arrow points downwards. If the arrow is shown in red, the current flow direction is inverted.
Power Logger Function Selection Buttons 31 2. Push  (Correct Digitally) to access the connection correction screen. This screen allows you to virtually swap phases and invert the current inputs instead of a manual correction. 3. If the Logger is able to determine a better phase map or polarity, push  (Auto Correct) to apply the new settings. Auto Correct is not available if the algorithm is not able to detect a better phase map or when no errors are detected. Note It is impossible to detect all incorrect hook-ups automatically. You must verify the suggested modifications carefully before you apply the digital correction. Applications with single-phase energy generation can deliver the wrong results when you apply the Auto Correct feature. The algorithm works in a way that creates in three phase systems a sequence with a clockwise phase rotation. Power  – In the Power mode you can get the values and a live trend chart for each phase (A, B, C or L1, L2, L3) and total as: • Active Power (P) in W • Apparent Power (S) in VA • Non-active Power (D) in var • Power Factor (PF) Use  (Fundamental/RMS) to toggle between full bandwidth power values and power of the fundamental.

If you confirm the selection, the Logger will adjust the averaging interval accordingly. Interval of the average calculation Select the time interval when a new average value is added to the logging session. The available intervals are: 1 s, 5 s, 10 s, 30 s, 1 min, 5 min, 10 min, 15 min, 30 min. A shorter interval provides more details at the cost of higher memory consumption. Examples of when a short interval is useful: • Identify duty cycle of frequently switching loads • Energy cost calculation of production steps The Logger recommends an interval based on the duration to get the best balance between resolution and data size. A memory gauge shows the memory used by recorded sessions and stored screenshots in black. The memory required for the new session is shown in green. In the case where the new logging session will not fit in the available memory, the gauge turns from green to red. It is still possible to confirm the selection but the Logger will adjust the duration accordingly. Demand Interval Electrical suppliers use this interval to measure the customer demand. Select an interval to get energy costs and the maximum demand value (average power measured over a demand interval). A value of 15 minutes is normal. If you don't know the average interval, select 5 minutes. You can recalculate other interval lengths offline using the Energy Analyze Plus software. Note This value is not available for load studies.

PQ Health Overview The PQ Health Overview is available on 1738 or 1736 with 1736/Upgrade or IEEE 519/Report license. This screen shows a pass/fail analysis based on limits defined by the power quality standard EN 50160. The screen includes the parameters for: • Frequency • Voltage Variations • Voltage Harmonics • Unbalance • Events The frequency, unbalance, and events have a single bar, voltage variations, and voltage harmonics shown in three bars that depend on the configured topology. The length of a bar increases if the related parameter is further away from its nominal value. The bar turns from green to red if a maximum allowed tolerance requirement is surpassed. When the standard defines two limits for a parameter (for example, voltage variations have a limit for 95 % of the time and limit for 100 % of the time) the bar changes from green to orange when the parameter surpasses the 95 % limit but does not exceed the 100 % limit. For more information go to www.fluke.com and search for the white paper, Measurement Methods.
1736/1738 Users Manual 38 The screen updates with each new average calculation interval of 10 minutes. From the PQ Health Home screen you have access to: • PQ Graphs • Harmonics • Events Quality Overview The Quality Overview screen shows an average of voltage THD and the first 25 voltage harmonics of up to three phases and the number of voltage events. The screen updates with each new average calculation interval of 10 minutes. From the PQ Health home screen you have access to: • PQ Graphs • Harmonics • Events PQ Graphs Use  (PQ Graphs) to review the graphs of the power quality parameters: Voltage, Frequency, and Supply Voltage Unbalance. The Voltage and Unbalance values are averaged every 10 minutes and the interval begins with the 10-minute clock tick. The time stamp of the interval represents the end of the interval. The Frequency is averaged over an interval of 10 seconds. New values are available every 10 minutes. The Unbalance value u2 (negative sequence ratio) is the ratio of negative sequence divided by positive sequence and is shown as a percentage. In the case of a counter-clockwise rotating system, the unbalance would show values exceeding 100 %. In this case the ratio positive sequence divided by negative system is calculated which results in values lower or equal to 100 %. Note The unbalance is only available in three phase delta and wye systems, excluding the balanced systems. Harmonics Use  (Harmonics) to access the harmonics analysis screens for voltage and current. Harmonics Spectrum The harmonics spectrum is a bar chart of the harmonics h02 ... h50. When % of the fundamental is selected, THD is included in the chart. The bar chart in absolute units (V RMS, A RMS) includes the fundamental. Use the trend chart to show the exact value.

Power Logger Function Selection Buttons 39 harmonics relative to the individual limit defined by the standard defined in the measurement configuration. Each bar is green when the measurement is below the individual limit for this harmonic or THD. When the standard defines two limits, for example, a limit for 95 % of all values and a limit for 99 % of all limits, the bar turns orange when the measurement values comply with the 99 % limit but violate the 95 % limit. When both limits are violated the bar turns red. When the standard defines only one limit for each harmonic or THD, the bar turns from green to red when this limit is violated. The number of displayed harmonics varies in accordance with the selected standard. The side menu in the harmonics screens has dual use. First, select the parameter to display and confirm with . The selector bar jumps to the lower section for the phase selection. The number of available phases and the Neutral current depends on the selected topology. Refer to Measurement Configuration for details. Make your choice and confirm again with . Some screens do not include  (Show Menu) to access the side menu. Use the cursor keys instead. Events The Logger captures events on voltage and current. The events are shown in a table with the columns ID, Start Time, End Time, Duration, Event Type, Extreme Value, Severity, and Phase. Touch the arrows left and right of the table to view all available columns. Use  to highlight an event of interest. On the 1738 or the 1736 with 1736/Upgrade license, use  (Waveshape) and  (RMS Profile) to review the recordings triggered with the start of the event. The voltage events are classified in dips, swells, and interruptions and are measured according to the standard IEC 61000–4–30 "Electromagnetic compatibility (EMC) - Part 4-30: Testing and measurement techniques - Power quality measurement methods". According to this standard the Logger applies the polyphase event detection on split phase and three phase systems with the exception of the topologies 3-phase Delta balanced and the 3-phase Wye balanced. The events are captured and reported for phase A/L1 only. Note The polyphase event detection simplifies the event table because events on multiple phases are combined when they occur at the same time or overlap. In the Energy Analyze Plus software you can select to get either a table with combined events using the polyphase event detection or a table with events for each individual phase in order to review details, like start time, end time, or the extreme value on an individual phase of interest.
1736/1738 Users Manual 40 Supply Voltage Swells On single-phase systems, a swell begins when the voltage rises above the swell threshold, and ends when the voltage is equal to or below the swell threshold minus the hysteresis voltage. See Figure 8. On polyphase systems, a swell begins when the voltage of one or more channels is above the swell threshold and ends when the voltage on all measured channels is equal to or below the swell threshold minus the hysteresis voltage. hcf071.eps Figure 8. Characteristics of a Voltage Swell On single-phase systems, a voltage dip begins when the voltage falls below the dip threshold, and ends when the voltage is equal to or above the dip threshold plus the hysteresis voltage.

See Figure 10. hcf072.eps Figure 10. Characteristics of a Voltage Interruption On polyphase systems, a voltage interruption begins when the voltages of all channels fall below the voltage interruption threshold and ends when the voltage on any one channel is equal to, or greater than, the voltage interruption threshold plus the hysteresis. Note On polyphase systems, the event is still classified as a dip when the voltage of only one or two phases falls below the interruption limit. Inrush Current Inrush currents are surge currents that occur when a large, or low-impedance load comes on line. Normally the current will stabilize after some time when the load has reached normal working condition. For example the start-up current in induction motors can be 10x the normal working current. See Figure 11. The inrush current begins when the 1/2cycle RMS current rises above the inrush threshold, and ends when the 1/2cycle RMS current is equal to or below the inrush threshold minus the hysteresis value. In the event table the extreme value is the highest 1/2cycle RMS value of the event. DurationNominal VoltageHysteresisThreshold0 Volt Time Magnitude

Power Logger First Measurements 49 The Logger is now ready for the first measurements or energy study. Note Be aware that for power measurements in 3-phase systems: • Total Active Power (W) is the sum of the individual phases • Total Apparent Power (VA) also includes the neutral current that can result in a very different result than the sum of the three phases. This is especially noticeable when a signal is connected to all three phases (for example, a calibrator) the total value is approximately 41% higher than the sum of each phase. • Total Fundamental Power (W and var) only delivers the sum of each phase when the phase rotation is clockwise. It is zero when the phase rotation is counter-clockwise. For more information, see the white paper, Measurement Theory Formulas, at www.fluke.com for a list of formulas. First Measurements At the energy study site, look at the information in the panel and the rating plates on the machines. Based on knowledge of the electrical supply in the facility, determine the configuration. To start measurements: 1. Connect the Logger to mains power. Note See page 16 if you want to power the Logger from the measurement line. The Logger starts and shows the Meter screen with Volts, Amps, and Hz readings. 2. Push Change Configuration.
