Test station is intended to test asynchronous and synchronous machines with the capacity from 100 up to 1000 kW with up to 6 kW voltage, and from 100 up to 400 kW with 0,66 kV voltage, transformers with capacity up to 2000 kVA with up to 10 kV voltage. Test station provides electric machine trials according to demands of the following technical standards: GOST 7217-87, GOST 183-74, GOST 10169-77, GOST 11828-86, GOST 3484-88, GOST 11677-85. Station equipment allows to perform the following trials: For electric motors: - measuring resistance of winding isolation in relation to body and between the phases; - measuring winding resistance offered to direct current in practically cold state; - testing winding isolation in relation to body and between the windings to prove electric stability; - idle running of electrical machine; - determination of idle current and losses; - determination of short circuit voltage and losses; - determination of transformation ratio (for electrical motors with phase rotor); - testing under increased frequency of rotation (for asynchronous machines with phase rotor and synchronous machines if rotation windings or bandages were under repair). - Electrical stability testing winding interloop isolation; - Idle running for synchronous machines. For transformers: - measuring resistance of winding isolation and absorption ratio; - determination of transformation ratio; - check up a set of winding connections; - testing electric stability of winding isolation by applying increased voltage of industrial frequency; - determination of idle current and losses; - determination of short circuit voltage and losses; - measuring winding resistance offered to direct current in practically cold state;
