Answer Posted / mprajaneb
restraining coils are used in the relay for controlling the
sensitivity characteristic of the relay. Differential
relays are highly sensitive relays. restraining coils
prevents the unwanted tripping of the transformer due to
the spill current due to CT saturation effect, or due to
the mismatch current due to CT characteristic.
