What is mean by Sensitive Earth fault & what are the effects
Answer / khrabsheh
Sensitive Earth Fault Protection Normally used on systems where the earth fault current is limited to a very low value (Neutral earthed through resistors, Peterson coil, reactance, etc) Scheme consists out of a ring CT (Core Balance CT) around the three phase conductors, and the relay connected to the secondary side of the CT. A very low setting is possible, even sometimes lower then 1% FLA. Need to coordinate with similar relays downstream.
