  • : subdivided on 7 pages
  • resistance or impedance towards ground + insulation TV temperature
  • resistance towards ground1+ capacity towards ground1
  • voltage + frequency
  • current
  • active power + apparent power
  • apparent power demand + apparent power max. demand
  • phase with lowest impedance towards ground + presence of remote repeaters
  • 1 present just if you select the impedance towards ground display
  • 2 measurements referred to the secondary winding of the external insulation VT
