Transformer short circuit test

October 9, 2006 12:51am CST
At my workplace we carryout short circuit tests and we normally inject on the HV side a voltage which gives us the rated primary current. We get the rated full load currents at the seconday side, although the input voltage for this test is just a small percentage of the rated primary voltage. I need to be assisted on one thing; What should be the minimum and maximum acceptable neutral current for this kind of test.
