Description: This paper describes important steps when
developing relays models inside a real time simulator. These
relays models, as the differential element inside real time
simulators, can improve the dependability of the tests. In the
present paper a commercial transformer differential element
model is described. In order to compare the model response to the
real relay, the last was connected to the real time simulator. Also
to enhance the range of the tests it was tested a built-in
differential model existent in the simulator library. All kind of
daily situations for a protection relay was tested including inrush
and internal faults to the power transformer. The simulations
were performed with RTDS.
