AC earth fault monitoring ISOPAK1

The purpose of ISOPAK1xx is to selectively detect and address earth faults in live 50 or 60 Hz networks. An intelligent highest up function highlights the highest level of hazard in the system, and only alerts the operator when conditions for an impending danger are present. SOPAK1xx can be configured for operation in FLOATING and GROUNDED single phase, 3-wire and 4 wire three phase AC networks.

DC earth fault monitoring

The purpose of ISOPAK2xx is to selectively address level and polarity of earth faults in live battery and DCpower supply networks. An intelligent highest up function highlights the highest level of hazard in the system and only alerts the operator when conditions for an impending danger are present. Earth faults arise when insulation levels decrease and residual current (earth current) flows fromone ormore of the network conductors to ground.

Three channele AC earth fault guard

The three channel digitally controlled KCM363x monitors up to three earth current channels in a non-grounded (IT) or grounded TN network and its protective earth. Unit can be used for either Restricted or Unrestricted earth fault detection.There is individual relay for alarm or trip of load breaker.

Earth Leakage Trip Relay AC

The KRM162B measures the insulation, directly in milli amps, of earthed AC systems. But it can also be used in IT-systems together with a constant impedance module type MML1501.

Earth fault protection

KPV12E is a digitally controlled two-level trip relay monitoring the insulation status of a live AC system, by detecting the displacement of the voltage between the supply system neutral point and PE.

Open delta earth fault guard

KPV14E is a digitally controlled triple zone (two-level) trip relay connected in an "open-delta" configuration. The unit detects changes in the neutral point voltage in a non-grounded high tension network, caused by insulation fault.

AC Generator current differential guard

KPC112E protects against phase-, earth- and winding faults within the protected area (the stator) of large AC generators. It detects even minute insulation punctures, flash-over carbon deposits and contamination.
