Selectable Insulation Monitor – type SIM-Q

The SIM-Q is used for supervision of the insulation resistance between an insulated voltage distribution network (IT network) and earth cable/safety cable.

Features include:

•    Insulation monitoring of AC networks up to 690V AC
•    Ideal for applications with frequency converters
•    Easy testing during vettings/inspections
•    Immune to DC voltages up to 1,000V
•    Classic fault-finding properties

Based on our patent pending technology, the SIM-Q combines the accuracy of digital insulation monitoring principles with the speed of traditional ohmic measuring. DEIF has utilised their experience gained from having manufactured insulation monitors for many years to invent an insulation monitor that eliminates the shortcomings of traditional designs; sensitivity to uneven stray capacitance, risk of damage caused by high network DC voltages (imposed by faulty frequency converters), etc.

The SIM-Q can be used for marine installations and other types of insulated voltage networks, e.g. containers.
