How to Test Numerical Differential Relay of a Transformer. I have studied the IEEE guide about the testing of numerical relay but i want you to share the experience of the testing of the differential relay. The IEEE research paper link is

if anybody want it.

Transformer Specs:

Step up transformer 175MVA 500KV/11KV

Hello Ans mehmood,
the most simple approach for site testing is to use a three-phase relay test set (such as those made by Omicron).
If instead you are dealing with prototype testing and validation, you can perform a more extensive testing procedure using real time digital simulators.
