MEASUREMENT OF TRANSFORMER WINDINGS RESISTANCE
Abstract
The article contains a theoretical rationale and describes the method of separate measurements of total, active and reactive resistance of transformer windings. Linear currents and voltages are measured, as well as power in the short-circuit experiment of a three-phase two-winding transformer or group of three identical two-winding singlephase transformers. From the values of the three phase power, average linear voltage and current values of short circuit resistance are calculated in delta and wye connection schemes of supply windings. Parameters of total, active and reactive resistance by short-circuit of any winding of multiwinding three-phase and single-phase transformers can be defined similarly, turning them into supply windings.
