ZX limiting impedance Vigilohm
  • Combination of R, L, C components
  • At 50Hz, its impedance is 1500ohms
  • To be connected in parallel with the Insulation Monitor and the Cardew
  • Small ungrounded networks below 500 VAC
  • Not compatible with healthcare and photovoltaic applications
Manufacturer: Merlin Gerin
This accessory belongs to the Vigilohm range designed to monitor ungrounded/IT electrical networks at feeder level, in accordance to installation and products standards. The limiting impedance subassembly prevents variation of potential. Useful if there is sensitive low-power equipment placed close to the medium to low voltage transformer, such as modem power supplies. This limiting impedance is not mandatory in a IT system. Need to be connected between the transformer and the earthed neutral. This accessory is mounted on a 190mm by 380mm plate, the subassembly weight 3.5 kilograms.
