626000732Summary
PQA7700 Power Quality Analyser
The PQA7700 is a handheld, simple to use, portable power quality analyser with four current and four voltage measuring channels. Integrated in a rugged housing and packed withpowerful functions it can be effectively used formonitoring, troubleshooting and analysing of power quality conditions in power distribution networks either in industry or utilities.
Features:
- 4 voltage channels with wide measurement range: 0 ÷ 1000 Vrms, CAT III/1000V
- 4 current channels with support for automatic clamp recognition and ‘on instrument’ range selection
- Compliance with power quality standard IEC 61000-4-30 Class S. Predefined recorder profile for EN 50160 survey
- Power measurements compliance with IEC 61557-12 and IEEE 1448
- Simultaneous 8 channels - 16bit AD conversion for accurate power measurements (minimal phase shift error)
- Simple to use and powerful recorder with possibility to record 509 different power quality signatures
- Voltage events and user defined alarms capture
- 15 hour of autonomous (battery) supply.
The following measuring functions are represented:
- Voltage: True RMS, peak, crest factor (4 channel)
- Current: True RMS, peak, creast factor (4 channel)
- Power: active, reactive, apparent
- Power factor, cos φ
- Unbalance, flicker measurement
- Harmonic analysis up to 50th
- Energy (active, reactive, generated, consumed)
- Power quality analysis according to EN50160
- Capturing and recording of power supply events (shut downs, interruptions, swells, dips
- Inrush currents monitoring and recording
- Recording up to 10 adjustable alarms
- Waveform displaying and snapshot
Application
