Transformer Differential Testing Techniques: 4 hours In the past we could test electromechanical transformer differential relays one phase at a time with little to no worry about undesirable operation of the scheme. With the advent of microprocessor relays it is becoming more difficult to arrive at this result. Three phase element based testing is becoming more prevalent due to the fact that the newer generation of relays has become smarter over the years. One other great advantage of three phase testing is it is one of the few ways to detect settings errors that can operate the differential element for external through faults. We will discuss the advantages of testing the relays as a scheme and examine the results of the total relay operation as a whole. Also, we will cover a few examples of case studies where single phase testing was done and the relay operated for external faults.
