  • Power Transformer Testing Methods - Type, Routine Special Tests

    Winding Resistance Measurement (Resistance) This transformer testing method is conducted to determine the resistance. Winding Resistance Measurement is one of the routine tests in a transformer. Ratio Measurement and Vector Relationship Check. This transformer testing method checks the Voltage Turns Ratio, Polarity, and Phase Relation of the transformer. No Load Loss and Excitation Current Measurement. Core Loss and Exciting Current. PURPOSE: To measure no-load loss (core loss) and excitation current, and verify that these values are within an acceptable tolerance of the calculated values. Load Loss and Impedance. PURPOSE: To determine, by test and calculation, load losses and total losses of a transformer under test. Also, to determine the impedance voltage of the transformer expressed as a percentage of the rated primary voltage, from which may be calculated the winding currents under short circuit conditions.
