What is the function of auxiliary relay in power station protection?
Auxiliary relay is a relay which will repeat the operations of protective relay such as tripping, time lag, breaking of trip circuit current, giving alarms and showing flags etc..Protective relay contacts are delicate and light weight hence it will not capable of carrying a large amount of current for a long period.protective relays do not have enough contacts to perform all the operations of protective scheme.Therefore auxiliary relays, auxiliary switches and repeat contacts are used to assist protective relays.

How does a 6volt relay circuit works?
The same as a 12V relay circuit, except it only needs 6V instead of 12V.
Why use relay insted of switch?
Because a switch is a 'permanent' action. A relay only completes the circuit while there is power. If there is a fault in the circuit, a switch will still allow power through, whereas a relay will break the circuit.
