PQA 7700 Power Quality Analyser


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. 


  • 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
