REF Relay is connected to the neutral current transformer and phases CT common point( CBCT style connection)

6.5 One Case Study: We need to find out stability resistorR stab, what is this Stabilizing Resistor,

Actually Stabilizing resister is resister which under external fault condition prevent relay to operate. Relay can be operated under high voltage condition.

Now let suppose we have below mention data stabilizing Voltage = V s = 39.549v I s, set = 0.1A pg. 229
