Record three-phase power quality and monitor for power quality disturbances with the Fluke 1750 Power Recorder and the Fluke Power Analyze software. These power meters automatically record every power quality parameter and event, on every cycle – all the time.
Key Features | |
Power quality that meets the standard: | All measurements comply with IEC61000-4-30 standards for correct evaluation of all measured values including voltage, current, power, harmonics, flicker etc. |
Ethernet interface: | Included Windows 10 tablet allows for quick setup and verification with waveform displays, meter screens, and phasor diagrams. |
Quick and reliable configuration: | Windows 10 tablet “front panel interface” provides the ability to verify setup without a laptop along with a window into what the instrument is recording. |
Threshold-free setup: | Apply thresholds after data is collected with Fluke Power Analyze Software so there is no need to worry about missed information due to incorrect set-up. |
Captures everything: | Cross-channel and current triggering capture every measurement, on every channel, every time. |
Intuitive PC software: | Easily analyze data and generate reports. Automated EN50160 reporting and compliance running directly on the supplied Windows 10 tablet. |
Plug and play: | Set up in minutes with self-identifying current probes and single-lead voltage connections. |
No need to reconnect wires: | Swap channels internally with the Windows 10 front panel or PC when connections are not correct. |
Measure every parameter: | voltage and current on three phases, neutral, and ground. |
5 MHz, 8000 Vpk waveform capture: | Get a detailed picture of even the shortest events. |
Quickly retrieve data: | With included SD memory card or via the 100BaseT ethernet connection. |
