FIELD: electricity.
SUBSTANCE: invention is related to the sphere of electric engineering and may be used for testing of synchronous machines at machine-building plants, at repair services and for their operation. In the mode of synchronous machine loading a wound-rotor machine is used as a loading machine. The rotor is excited from three-phase current source with zero frequency set independently, with the rotor field rotation to any set angle and potential loading of the tested machine in motoring and generator modes, including load angels higher than the critical angle of load.
EFFECT: improving accuracy of efficiency factor measurement, expansion of functional capabilities in regard to the value of transmitted power.
