Hello everyone, I am Rose. Welcome back to the new post today. Relay is an autonomous electrical appliance used in electric drive systems for control, protection, and signal conversion. It is suitable for remote connection and disconnection of AC and DC small-capacity control circuits. ...
In electrical engineering, especially in electricity transmission and distribution networks, a protective relay is used to trip a circuit breaker when a fault is detected. In these systems, protection needs to be provided against various conditions like overcurrent, overvoltage, reverse power flow, ...
Buchholz relay is a type of protection relay universally used on all oil-immersed transformers with a rating of more than 500 kVA. In this article, you will learn to understand its principles and workings.
In addition to electrical relays, the most widely used relay is the “time relay”. Under normal circumstances, these relays have a certain delay corresponding to the signal used for the relay input, which is why the term “delay relay” is often used. Since the state change of the relay...
