A scheme where a signal is sent to to a remote location to cause a trip. An example could be a breaker failure scheme. When the breaker is told to trip, and fails to do so, fiber communications could be used to transmit a trip signal from the local substation to the substation the next bus out to cause that breaker to trip.

What is difference between high impedance busbar protection scheme and low impedance busbar protection scheme?
high impedance circit provides a varistor unit which has stabilising resistor which ll protect the relay from being operating for maloperations like through fault, CT faults whereas this varistor unit is provided internally in an numerical relay where the CT of class 5P can be used.
What is inter trip relay?
A protection signalling system whereby a signal initiated at one station trips a circuit-breaker at another station.
Why is there a ground wire?
The ground earth wire serves two purposes: To trip the protection as quickly as possible if theres an out of balanced current or a fault to earth. and to bring the user to the same potential to the earth if there is a fault and the protection doesnt trip. that way because you are at the same potential as earth you will not get electrocuted.
Restricted earth fault protection circuit?
Restricted earth fault protection is used to protect a specific zone, and should not trip for a fault outside of that zone (usually limited to a transformer, and possibly extending to lowside, highside, and tertiary breakers).
Why is it necessary to have a no volt protection in motor circuits?
The protection is there to prevent motors starting up on their own after a power failure. This could lead to very unsafe conditions. Also in a big industrial factory if everything started up at once the demand load could trip the main breaker. With the protection in the circuit each and every motor is started up independently.
How does the Deposit Protection Scheme for landlords in the UK work?

What is auto bus transfer scheme?
As per two incomers and one buscoupler configuration , buscoupler automatically close after tripping of any one of incomer will trip under fault condition or u/v condition or there is no voltage in bus ie dead bus closing.
What is Trip circuit supervision?
Trip circuit supervision is defined as the protection equipment which monitors the continuity of the trip circuits of a circuit-breaker. The trip circuit supervision relay will monitor the proper functioning of trip circuits.
