Draw differential relay & explain its working? Exp arcing , its initiation & extinguisher technique

Question

Accepted Answer

A differential relay is a protective device that detects and responds to the difference in current between two or more circuits.

Differential relays are commonly used in power systems to protect electrical equipment from faults.
They operate by comparing the current entering a circuit with the current leaving the circuit.
If there is a difference in current, it indicates a fault and the relay initiates a trip signal to isolate the faulty circuit.
Arcing is the phenomenon of an electric current flowing through the air between two conductors, resulting in the formation of an arc.
Arcing can be initiated by various factors such as high voltage, insulation breakdown, or faulty equipment.
To extinguish an arc, different techniques can be used, including arc quenching devices like circuit breakers or arc suppression coils.
