HRN-5 Overvoltage Recorder

A self-contained unit designed for recording of intermittent, atmospheric or switching overvoltage.

Recorder features

  • Recording of the time, when equipment voltage exceeded one of five voltage levels
  • The individual voltage levels adjustable from 50 % to 600 % of the rated phase voltage of the monitored equipment
  • Registering of an overvoltage pulse as short as 1 µs
  • Connection of the recording unit
    • In low-voltage circuits directly to phase conductors using test leads
    • In medium-voltage circuits to capacitive voltage dividers firmly connected to phase conductors
    • In high-voltage circuits to diagnostic output of capacitive penetrations of main transformers via an appropriately designed capacitive element
  • Capacitive dividers for 6 kV, 24 kV and 400 kV networks are available as accessories
  • Original LOGA software for effective data processing, displaying of component state versus time and report printing
  • Fully automatic recorder operation
  • Robust design suitable for industrial applications
  • High reliability
