Abstract: In any electrical distribution system distribution transformer considered as a heart of the system. For this reason, a working transformer should be reliable. The main problem associated with the distribution transformer is overloading, which causes the failure of the transformer and thus the whole system gets affected and makes the system unreliable. Overloading of the transformer means taking more current than it’s designed value of the transformer secondary. To take the control over this overloading issue, we have a solution called ‘protective relay’. Generally, protective relay works on the electromagnetic principle. It protects the transformer in an overload condition. A protective relay is generally coupled with the circuit breaker, which isolates the system in overload conditions. In this paper, we have used the microcontroller for designing this protecting relay. Microcontroller based relays are more popular because of no mechanical operation.
