How does a pilot wire differential scheme provide line protection?

How does a current differential protection scheme handle line charging current?
Answer : A current differential protection scheme is typically used to protect transmission lines by detecting fault currents. However, when it comes to line charging currents (the current flowing through the ... the protection only operates during actual faults, not due to normal line charging conditions....
