Liona online PD spot tester

liona is a portable online PD spot tester for measuring and locating partial discharges in cables and switchgear during normal mains operation. liona allows the testing of cable systems and electrical equipment for partial discharge activities online and without having to switch

Features

  • Applications
  • Online PD spot testing (typical 5 to 10 minutes per cable):
  • Allows a large number of MV and HV plantitems to be tested for PD activities
  • Online PD mapping:
  • Allows to identify the source of the PD along the cable with the iPD transponder during normal operation of the cable route
  • Monitoring of PD activities during 24-hour commissioning test of MV and HV cables at normal operation voltage (according to IEC 60840)
  • Periodically PD monitoring of critical cable routes (e.g. industrial plants) with fixed installed sensors where no direct access during normal operation is possible
  • Measurement of partial discharges in MV and HV cables up to 4 km in length without interrupting mains operation
