Insulation relay for non-ground AC systems

  • Model:


  • Request Code:


  • Company:


  • Country:


The digitally controlled KRM16xE uses the Megacon "IDV" insulation measuring principle and monitors insulation level between a non-grounded (IT) mains and its protective earth. Unit is AC powered. Only ONE KRM16xE can be connected to each IT-system. The status LED gives the clear safety message: ALARM: Red LED NORMAL: Green LED The unit injects a DC 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. Features: -Direct connection up to 690V line voltage, up to 6,6kV with HV adapter -Monitoring during both live and standby conditions -For use in industrial, marine, offshore installations -"Easy view" status presentation -Immune to earth capacitance and voltage surges -Analogue output proportional to meter reading -Adjustable alarm setpoint Borna niroo karan company (Brnika) is Exclusive Representative of Megacon , in the purchase, sales, consulting and distribution and industrial equipment and measurement equipment, including Insulation Monitoring and so is active .
