ICM impulse current method
Pre-location / ICM impulse current method
ICM
Impulse current method for locating high-resistive faults and breakdown faults. The fault distance is determined by analysing the impulse current diagrams. Particularly suitable for use on long cables.
DC-ICM
Impulse current method used in DC mode for locating chargeable breakdown faults for which the cable capacitance is used in conjunction with a surge voltage generator.
