KPM16xM — AC INSULATION GUARD WITH HIGH ENERGY DC PROTECTION Direct connection up to 500V line voltage, up to 6,6kV with HV adapter Monitoring during both live and standby conditions Protection against harmful DC voltage exposure ‘Megger’ — safe to 1.4kVDC when aux power is OFF Immune to earth capacitance and voltage surges For use in land, marine, offshore, sub-sea and ocean floor Installations Analogue output proportional to meter reading (F-version) Application The digitally controlled KPM16xM 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) in marine and offshore installations. IDV MEASURING PRINCIPLE Insulation is measured between the complete galvanically interconnected AC network and its protective earth. The unit injects a sequentially coded measuring signal to 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. 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 KPM16xM can be connected to each IT-system
