HIGH IMMUNITY EARTH FAULT INDICATOR

HIGH IMMUNITY EARTH FAULT INDICATOR

The EEFI RR MKII was developed to meet the very stringent needs of one of our UK clients who demanded a very high degree of immunity from electro-magnetic fields induced into the C/T surrounding the HV cable. HV Cable Insulation test equipment was prone to trip standard EFIs, so a higher degree of protection was required. A plug in battery makes for easy battery change after a predicted 10 year life.
