1 1750 Power Recorder Operators Manual Introduction The Fluke 1750 Power Recorder is a comprehensive yet easy to use system for power quality investigations. The 1750 Power Recorder, referred to hereafter as simply “the Recorder”, consists of a power recorder instrument, a wireless handheld Personal Digital Assistant (PDA) for control and setup, and a powerful yet easy to use PC application, Power Analyze. Four 400 A current probes are provided as standard equipment. A wide range of ferro and Rogowski (flexible) type current probes are available from Fluke. Key features of the 1750 Power Recorder are: • No PC needed for setup Using the included a wireless-enabled Personal Digital Assistant (PDA) as a controller, you do not need a PC to configure the Recorder, troubleshoot connections, preview data, or download the recorded data. The range of the PDA with the wireless link is about 15 meters (45 feet) from the Recorder. • Simplified test lead connections to the power network Differential inputs are not required due to internal referencing from phase channel to phase channel. This means you simply connect a voltage probe to a conductor on each phase that you want to record. On the current inputs, there is an identification resistor in the connector that the Recorder uses to determine which probe is attached. The Recorder then configures its measurement system appropriately for the model of current probe you are using. • Connection diagrams for the supported power network configurations (delta, Wye, and others) appear on the handheld PDA controller. Once you make connections, you can view live readings and a PHASOR diagram on the PDA to confirm the connections. If a phase channel is wired incorrectly, you can swap the phase to another channel by changing an internal Recorder software setting using the PDA, and then reconfirm correct readings. • Internal Uninterruptible Power Supply (UPS) An internal NiMH (Nickel-Metal-Hydride) battery pack and charging system maintain data capture continuity through power interruptions of 5 minutes or less. • Automatic disturbance capture The Recorder uses an automatic, self-learning threshold routine, which means you do not have to set any event threshold limits before you start recording. You detect and display power quality events (disturbances) using the Power Analyze software on a PC after the event has been captured.
1750 Operators Manual 2 With these features, there is little else required to set up and start recording the data to conduct a power quality survey. Should you want to extensively analyze collected data, the procedures described later in this manual review the transfer of data from the Recorder to the PDA, and finally to a PC. Data may then be analyzed using Power Analyze on a PC. Extensive online help is provided in the Power Analyze software on the product CD shipped with the Recorder.

Installing the Power Recorder at a Facility This section describes the steps you need to take to set up the Recorder at a facility and begin a recording session. Work Flow There are three distinct stages for a recording session. • Set-up Set-up, hookup, and verification of connections and measured signals. This is when you will want to clear the Recorder memory, make any desired Recorder setting changes, and insert annotations and/or an optional Start mark into the recorded data stream. Annotations are messages or notes you insert into the data stream during a recording session. • Interim checkup, mid-recording session At this time, you may want to re-check all the live input signals, and download the data recorded since the beginning of the recording session. Annotation capability is always available during the recording session.
1750 Operators Manual 14 • End of recording session You can re-verify if desired, correctness of live data and then download data, power off the Recorder, and pack up fir transport. Installing the Recorder To install the Recorder at a facility, follow the basic steps below. 1. Position the Recorder within 2.5 m (8 ft) of the monitoring location. 2. The Recorder can be set on the floor or a table, or attached and secured to a pole or other mounting surface. 3. Connect the Recorder to a 100 to 240 V ac power source. • Connect the power cord to the Recorder using the appropriate supplied adapter. • Connect the power cord to a properly grounded wall outlet. WCaution Be sure to plug the power cord into the Recorder panel BEFORE connecting it to an outlet 4. Plug the power cord into a properly grounded wall outlet. 5. Turn on the PDA and tap the Power View icon to launch Power View. 6. If a Recorder is within range and is not password protected, the Home screen for live data appears. 7. If more than one Recorder is within range, select one Recorder for use. 8. If you have established password protection, you must type the correct password in the Password text box and tap the Enter button. (Password protection is established for a specific Recorder using either the Setup Password menu in Power View or the Power Analyze software). 9. All LEDs should flash ON, then OFF, and then each should turn ON and OFF in sequence. The LEDs will then remain on if you make a secure connection and there is sufficient voltage and current. Connecting the Recorder to the Wiring After you have set up the Recorder you are ready to connect the clamps and probes to the wiring. Refer to the Power Type diagrams provided on the PDA or in the 1750 Operators Manual. In most cases, you should install the current clamps first. Because they are clamped around wires, current clamps are usually more secure than voltage probes. Examine the conductors you are about to connect to and determine if you should attach the current clamps to the phase wires before you connect the voltage probes. 1. Select and attach the appropriate current clamps to the Recorder. 2. Select and attach the appropriate voltage probes to the Recorder. Note If your power connections require potential transformers (PTs) or current transformers (CTs), you can use the ratio settings in Power View to set the Recorder to display readings as they exist on the primary side of the PT and CT (for example, 12000 V).
Operators Manual Installing the Power Recorder at a Facility 15 WCaution Make sure the current clamps and voltage probes are paired correctly. The leads for the current clamp and voltage probe of the same color should be attached to the same phase wire or busbar. 3. Connect the Recorder to the wiring by first connecting the ground probe to the distribution system ground, and then the neutral probe to neutral. 4. With the ground clamp to the distribution system ground and the neutral clamp to neutral connect the current clamps. 5. Connect the remaining current clamps. • The arrow on the clamp should point toward the load. • Use the color-coding on the leads to help you connect the probes to the correct phases, neutral and ground. 6. Connect the remaining voltage probes. Note Make sure the voltage probes and current clamps are paired correctly. Calculations are made in pairs and cannot be changed after data is recorded. The leads for the voltage probe and current clamp of the same color should be attached to the same phase wire or busbar. 7. Check the LED for each phase to make sure a connection is established. • When a phase LED is ON or lighted, you know that the connection is active and that voltage and current is within the normal range. • When a phase LED is BLINKING, you are connected but the voltage or current is exceeding the normal range or exceeding the range of the probe that you are using. • When a current LED is OFF or unlit, there is insufficient current present in the line. Verifying Your Connection Before you leave the Recorder to accumulate data at the facility, double-check the connections. • Make sure the current clamps are secured and completely closed around the conductors and that the voltage and current LEDs are steady-on. • Use the PHASOR screen on the PDA to verify that the voltage and current connections are correct. You can swap the connections using Power View if they are incorrect. Finishing UP After making any corrections to the connections, recheck the PHASOR diagrams to confirm your connection. Make sure the nominal voltage, nominal line frequency, and power type (delta, wye, other) are correct before you leave the Recorder. It is a good practice to insert a Start Mark when you are finished with all settings so you can download data and ignore useless readings and events common at the beginning probe connecting activities.
1750 Operators Manual 16 Managing Recorded Data Recorded data resides in the Recorder on an internal non-accessible flash memory circuit. It is not transferred to an SD memory card in the Recorder’s SD memory slot until you request a download action using the PDA or an attached PC. It is never necessary to erase internal memory. When the Recorder has new data to record, it does so automatically, overwriting the oldest data. You can erase internal memory, if you want to simplify what you will be seeing in the download data screen. The start and end times will represent one recording session when old data is erased. Note Data is not removed from internal Recorder memory until you erase it using Power View software on the PDA or Power Analyze software on your PC. Power Type Diagrams The wiring illustrations included cover the standard power configurations that are selectable in Power View or Power Analyze software. The diagrams are provided as an aid in making the correct test lead connections. Power type diagrams are also included on your PDA and can be referenced when you are setting up nominal power on the Recorder. Available power type settings are: • One-Phase Plus Neutral • One-Phase IT No Neutral • One-Phase-Split Phase • Three-Phase Wye • Three-Phase Delta • Three-Phase IT • Three-Phase High Leg • Three-Phase Open Leg • 2-Element Delta • 2 ½-Element Wye

The Power View software installed on the PDA is designed to function as a remote front panel for the Recorder, since the Recorder itself is a “black box” with no integral display or external controls other than status LEDs. With Power View installed on the PDA, you are relieved of the burden of having to carry a laptop and Ethernet cable to a remote site when setting up the Recorder, checking its progress, or finishing a monitoring session. You can alternatively connect to a Recorder from a PC directly using an Ethernet cable or remotely over an IP network. You can then use Fluke Power Analyze to set up the Recorder, view power measurements wherever the Recorder is installed, or download data from the Recorder. Power View communicates with the PDA using a wireless controller radio interface. There is no provision for a hardwired PDA interface to the Ethernet port on the Recorder. After data is recorded and downloaded to a PC, you can analyze the recorded data using the Power Analyze software.

Connecting to the Recorder
1750 Operators Manual 28 Navigating in Power View on the PDA The Menu Bar on the bottom of the Power View screen allows you to quickly and easily configure a connected Recorder, view live data, and transfer data to the Secure Data (SD) card for viewing and analysis on your desktop computer using the companion Power Analyze software. Power View Menus Data Brings up the memory management screens which are for download to the SD card inserted in the Recorder and for erasing Recorder internal memory erasing and SD card files. View Brings up a list of the live detail views: Scope, Meter, Phasor, Harmonics, and Trend. There are configurable detail views of each type of screen available by tapping the sector of interest or the View menu. Once a detail view is selected, navigation to all available detail views is accomplished using the View menu. Setup Brings up the Recorder Setup menu, which allows you to configure the Recorder and set recording period information. Using this function, you can tap the appropriate icon to set the following : • Clock • Nominal Volts Nominal voltage and frequency values are auto-detected by the Recorder and shown as the defaults. These settings can be overwritten, forcing the Recorder to change its internal configuration to optimize power quality data recording for custom settings. • Volts and Current Scale • Passwords • Power Type Diagrams • Phase Swap • Probe Detect Icons on the Menu Bar Toggles between voltage and current waveforms. The PHASOR screen always shows both V & I (volts and amps). This icon is replaced with the icon on the detail views, as voltage and current data can be viewed simultaneously. In all the detail live view screens, a line selection menu is available using the button at the bottom. This is a checkbox that is used to select the voltage and current channels you want to display. This icon triggers the Recorder to capture high-resolution waveform data and save it in the recorded data stream. This waveform capture is identical to the “snapshot period” which can set up to happen automatically in the Recorder Setup menu.
Operators Manual Navigating in Power View on the PDA 29 This icon brings up the Annotate screen. Use the annotate menu to enter text or to insert a file and load it into the recorded data stream in the Recorder. Annotations can be used to make notes, or to insert an image or audio file name. You can enter multiple start and stop annotations. Start and stop annotations are not paired and are not restricted to being used as literally “start” and “stop”. Annotations are often done at the start of a power recording session. [keyboard] This icon brings up the standard PDA data entry keyboard.

Operators Manual Viewing Live Data 37 Viewing Live Data The View menu is used to view live data on the circuits on the circuits for example, Scope, Meter, Phasor, or Harmonics. Scope Screen The Scope screen shows 1.5 cycle waveform data for the volts and amp lines selected in the check boxes on Phase View screen. Tap the Phase icon ( ) to display the Phase View screen.
1750 Operators Manual 38 Meter Screen The Meter screen shows numeric readings for all selected phases. Phasor Screen The PHASOR screen shows voltage (long arrows with solid arrowheads), current amplitudes, and phase angles. This screen is used to verify proper test lead and current probe connections. You can easily correct an erroneous Recorder connection by going directly to Setup\Phase Swap ( ) and using the Recorder to internally invert a CT, swap a voltage or CT phase, or modify a scaling parameter, then return to the screen to verify that the correction has been made. There is no need to touch the cables. See “Phase Swap” later in the manual for additional information.
Operators Manual Viewing Live Data 39 Trend Screen The Trend screen shows live data being recorded as a strip chart display of the selected phases of voltage or current. This moment in time is visible on the right side of the graph. The traces fill the screen in 10 minutes, and continue FIFO (first-in, first-out). This feature is intended to paint a picture of the short-term stability of the power system. Harmonics Screen The Harmonics screen shows the magnitudes of the selected phases of V and I. The scale is % of nominal. The slider control displays harmonics of a higher order up to the 50th. If the power type is delta, V phases are AB, BC, and CA (L1L2, L2L3, L3L1 is available as a localized European labeling scheme). If the power type is Wye, V phases are AN, BN, CN, and NG. (N = neutral, G = ground).
1750 Operators Manual 40 Viewing Phases In all the detail Live View screen, a line selection menu is available using the button at the bottom. The Phase Selection screen reveals check boxes for selecting the voltage and current channels you want to display. Setting Up the Recorder To adjust the settings of the Recorder, tap Setup > 1750 Setup. The Setup screen shows set up options, with icons for available actions.
Operators Manual Setting Up the Recorder 41 From the Setup screen, you can adjust either the recording period information or the Recorder settings. Tap an icon on the Setup screen to view or configure: • Clock • Probe Detect • IP Address • Nominal Power • Instrument Name/Password • Phase Swap • Volts/Current Ratio • Snapshot Period Setting the Clock Use this feature to set the PDA clock or clock to synchronize the Recorder with the PDA clock.
1750 Operators Manual 42 Probe Detect This screen shows the types of probes attached to the Recorder current inputs. Current probes are automatically detected.
Operators Manual Setting Up the Recorder 43 Setting the IP Address Select Automatically Obtain Address unless your company's IT department has specific requirements that require assigned IP addresses. Overwriting Nominal Power Values Nominal power values are auto-detected by the Recorder and shown as the defaults. You can overwrite these settings by change the Recorder’s internal configuration to optimize power quality data recording custom settings.
1750 Operators Manual 44 Assign Recorder Name and Password Use this feature to assign a name identifier to the Recorder and to establish a password for the Recorder. This naming feature is designed to help you keep track of which Recorder is in use. Using Phase Swap Rather than having to change the physical connections to the power system, use the Phase Swap feature to make a software-selectable correction without physically switching the cable. You can select from the following: • Swap any voltage input • Swap any current input • Invert any current input clamp The screen shows check boxes to invert any current probe. Current probes are directional, and selecting “invert” has the effect of removing the probe and turning it around. If the power type is delta, V phases are AB, BC, and CA (L1L2, L2L3, L3L1 is available as an optional setting). If the power type is Wye, V phases are AN, BN, CN, and NG. (N = neutral, G = ground).
Operators Manual Setting Up the Recorder 45 Setting the Volts and Current Ratio Use this menu to add a ratio factor to the voltage or current input on each phase. Changing the first “1” in each case if there is a potential transformer in series with the voltage connection such as when you want to monitor a medium-voltage network using PTs and CTs to scale the voltage and current to a convenient level for measuring instruments. The current ratio applies a ratio to the current input in order to show the current present on a medium-voltage network. This feature is intended to be used for sensing low levels of current to represent the much higher levels on the primary side at a substation or step-down transformer that has built-in metering current transformers.
1750 Operators Manual 46 Setting the Snapshot Period - Periodic Waveform Capture Setting Use the Snapshot Period screen to program the Recorder to take automatic power conditions readings which are then stored in the recorded data stream. • None • 10 minutes • 30 minutes • 1 hour Note You can take a snapshot manually at any time at any time while connected over the wireless link to a Recorder. Press the Waveform icon on any of the View screens to take a snapshot. The message, “Snapshot Acquired” confirms that a snapshot was taken.
Operators Manual Setting Up the Recorder 47 Working with Annotations Annotations are optional markers that can be inserted by the Recorder operator to flag a particular point in the data when recording. They are usually inserted on using Power View with the wireless PDA. There are five types of annotations: • Start annotation (green) The Start annotation can be used to signify where important data begins. For example, the operator might want to establish a start annotation after having finished all probe connections and instrument setup, to indicate that any preceding data was preliminary. Note You are not limited to using the Start and Stop annotations in pairs, or to show a range of data. You can use each as many times as desired to mark a particular point during recording. • Stop annotation (red) The Stop annotation can be used to signify where important data ends. • File annotation (yellow) File annotations contain the name of a picture or audio file relevant to the data. See “Using Image or Voice Annotations” later in this manual. • Text annotation Text annotations contain a text note. • Power Configuration Change annotation Power Configuration Change annotations are inserted by the system when a change is made to the Power Configuration in the Recorder. These markers only display in the Download dialog box. To show or hide annotation markers • In the Volts/Amps/Hz or Events view, check or uncheck the Annotations option on the view controls. To open an annotation • In the Volts/Amps/Hz view, Events view, or Download dialog box, click on the annotation.
1750 Operators Manual 48 If the annotation is associated with an audio (.WAV) or image (.jpg) file, the application associated with that file will start and open the file. If the file is not in the default directory My Documents\PQ, a dialog box opens so that you can navigate to the file. Note If clicking on an annotation marker does not seem to do anything, the Zoom box is probably selected in the graph toolbar, instead of the Select tool. Click the Select tool and then select the annotation. To see overlapping annotations Sometimes annotations are so close to each other that they actually overlap on the Volts/Amps/Hz reference graph. When this is the case, if you click on overlapping annotations, a menu opens and you can select either Open, to open the annotation now on top, or Select Next Overlapping Annotation, to bring the next one to the top. • To open the annotation now on top, choose Open. • To bring the next annotation to the top, choose Select Next Overlapping Annotation. To then open that annotation, click on it again and choose Open. Note To see overlapping annotations more clearly on the Volts/Amps/Hz reference graph, move the selection cursors so that they just surround the area that contains the overlapping illustrations. The Detail graph adjusts as the cursors move, zooming in to show the area between the selection cursors. You can now see the annotations separately. Using Image or Voice Annotations While you are monitoring data with a Recorder, you may find it helpful to take a picture that relates to the power quality data you are recording, or to record verbal comments as you observe the conditions or review the data being measured. You can then associate the image or recording with the data being recorded by adding annotations that reference them. The PDA includes a microphone for recording notes which are saved as .WAV files, and an optional camera accessory is available on the PDA which will capture images as .jpg files. You can associate both images and audio files with the data being gathered in the Recorder by inserting annotations and specifying the name of a .WAV or .jpg file. After you download data from the Recorder, you can then move the image and audio files to the PC along with the recorded data (.odn) file. Note You can also associate other types of files with the annotation. For example, if you had a .MPJ file with a movie, or a .DOC file with associated information. You can enter any file name using this annotation method. Inserting Image or Voice Annotations 1. Set up the Recorder and begin monitoring. 2. Using your PDA-cam or another camera, take a picture of what you want to capture. 3. Click the Annotate icon to display the Annotate screen.
Operators Manual Cleaning and Maintenance 49 4. Move the image or audio file to a location that will make it easier to Transfer it to a PC later, when you download and move the recorded data file to your PC. Place the file into the synchronization folder on your PDA, so that it will be automatically transferred into the sync folder on the PC the next time you dock the PDA.
