HIGH IMMUNITY EARTH FAULT INDICATOR
The EEFI RR MKIII was developed to meet the 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 replaceable battery makes for easy change after a predicted 15 year life.
