Abstract:
A system and a method for determining the power loss of a transformer. The method includes measuring voltage and current at the primary side of the transformer, calculating input power by multiplying the measured current and voltage on the primary side of the transformer; measuring voltage and current at the secondary side of the transformer, calculate a nominal error ratio, calculating output power by multiplying the measured current and voltage on the secondary side of the transformer. The method further involves calculating a first corrected power loss by means of multiplying the input power with the nominal error ratio and subtract the output power.

Claim (Index 4):
A system for determining power loss in a transformer, including:\n an input voltage measurement apparatus and an input current measurement apparatus configured to be connected to a primary winding of a transformer( 100 ), and an output current measurement apparatus and an output voltage measurement apparatus configured to be connected to a secondary winding of the transformer; a calculation device configured to be connected to the input current measurement apparatus, the input voltage measurement apparatus, the output current measurement apparatus, and the output voltage measurement apparatus, the calculation device is configured to receive information about each measurement, which includes measured voltages and currents, wherein the calculation device is configured to:\n calculate the input power by multiplying the measured current and voltage of the primary side of the transformer; \n calculate a nominal error ratio; \n calculate the output power by multiplying the measured output current and output voltage on the secondary side of the transformer; \n calculate a first corrected power loss by means of multiplying the input power with a first correction factor which is the complex conjugate of the nominal error ratio and subtract the output power, \n wherein the calculation device is configured to calculate the nominal error ratio as:\n n \u02dc /n =(1+\u03b5 IL )/(1+\u03b5 IH ) \n \n where \u03b5 IL  is a complex number representing the error in the current measurement on the secondary side of the transformer, and \u03b5 IH  is a complex number representing the error in the current measurement on the primary side of the transformer.
