A 100/S00 V. 1 KVA, 50 Hz transformer was put through open and short-circuit tests to find its internal parameters. The test conditions and derived parameters are as follows Open circut test: The high voltage side terminals were open. The low voltäge side was connected to 10020ª, 50 Hz supply. The low voltage side current was measured as 50245º MA. Short-circuit test The high voltage side terminals were short-circuited. The low voltage side was connected to a variable voltage supply (50 Hz). A full load current of 102-30° A was achieved when the variable voltage supply was at 820° V.
