Smart Relay Board for Short Transmission System

In the short transmission line and power system or some other company there are many equipment used in which may be transformer or generator. If any faults occur in transformer and generator as a results transmission line and may be system faults condition occurred, so it required protection of the transmission line or system relay. So if we use the different –different relay for different-different protection, it will be a costlier. Hence we use the one relay with the help of micro-controller and different sensor circuit which provide protection against the over voltage, under voltage fault, over current and under current fault, thermal faults, single phasing and gausses faults. The sensor circuit sense the different quantity means temperature sensor sense the temperature if it will grater then the rated temperature the micro-controller produced the tripping signal and relay will be tripped and faulty section gas sensor sense the quantity of gas and also voltage and current variac measure the voltage and current and if it greater than or if below the rated quantity then the micro-controller produced the tripping signal and relay will be tripped and faulty section will be isolated.
