power qualityportable

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
