transformer protection can b done by-
1)using buccholtz relays - this relay basically is connectd in the pipe between d main transformer oil tank and the conservator tank.whenever slight overloadin results
d trans4mer oil vapourises thus d oil in d main tank moves 2wrds d conservator dus cozin the float to drip lower n the alarm 2 switch on . in case of faults d level of oil decreases in d oil tank n dus the float causes d circuit 2 trip 2 prevent damag 2 d trans4mer .
2)differential protection -if the differenc between d primary n scndry current increases beyond a certain limit d trans4mer circuit is disconnectd 4rm d circuit

What is discrimination factor of electrical circuit protection?
Electrical discrimination is to do with selecting the correct protection in the fault path of an electrical circuit. To illustrate, if you have a machine at the end of an electircal circuit and that is protected by a 13A fuse lets say, and then you have a 20A circuit breaker protecting that at the consumer unit (fuse board), and then the main switch on the consumer unit is a 10A circuit breaker, then every time the machine uses more than 10A of power the main switch will trip and disconnect everything connected to it, that is where discrimination is not achieved. Basically it is where the circuit protection closest to the macine is smaller and it gets bigger as it goes boack to the source, then discimination is achieved. I hope that helps. If not then it probably need a drawing to help answer.
