The digitally controlled MCM163x series monitors insulation level between a non-grounded (IT) AC mains and its protective earth, regardless of whether the mains is live or non-live (standby).
An AC or DC auxiliary voltage is required for the unit, if powered from a separate source the network can also be monitored during standby conditions. Only ONE MCM163x can be connected to each IT-system.
The unit injects a sequentially coded measuring signal into the monitored system. The signal flows to ground via the path of the insulation fault, the level of flow indicates the insulation resistance. The measuring accuracy is not influenced by any normal kind of load attached to the AC network.
-Direct connection up to 690V line voltage, up to 6,6kV with HV adapter
-Monitoring during both live and standby conditions
-For use in land, marine, offshore, sub-sea and ocean floor Installations
-Comply with AODC 035 Code of Practice
-"Megger" - safe to 1,4kVDC when aux power is OFF
-Immune to earth capacitance and voltage surges
-Analogue output proportional to meter reading
-Optional slave indicator
