what is the difference between a balanced voltage relay and a translay relay

Answer 1

A balanced voltage relay and a translay relay

Different types of relays are utilized for power system protection. A widely popular relay among them for shielding transformers and generators from localized disturbances is the differential relay.

However, they are least susceptible to faults outside the protected zone. Differential relays are particularly sensitive to faults that occur inside the protection zone. Most relays switch on when a quantity goes above and beyond a specified value. For instance, an over-current relay switches when the current flowing through it exceeds a predetermined number. However, the differential relay operates on a somewhat different premise. It functions based on the difference between two or more electrical variables that are comparable to one another.

What is a relay for voltage balance?

• Application. For three-phase systems, the Type 60 Voltage Balance Relay offers quick differential voltage sensing. Detecting a blown a fuse in a potential trans-former circuit is a frequent application, as is the prevention of erroneous tripping or the failure of other devices due to voltage loss.

A Translay relay: what is it?

• A differential relay is what the translay relay is. The secondary winding is not closed on itself, but the setup is analogous to an overcurrent relay. The Translay scheme is the relay type employed in the feeder protection.
