The best method for a clear picture of finding out regulation of a transformer is to do actual load test with varying power factor with 10-25% over loading. However, if the size of the transformer is a constraint to arrange for large loads, OC/SC test must be done to determine the impedance of the transformer at different loading conditions indirectly and indirectly obtain the regulation graph.

SC Test Only... But also need to know about PF of the Load as V.R. of transformer depends on PF of Load
