02.01.09 Test station for AC electric machines with capacity from 100 up to 1000 kW

Test station is intended to test AC asynchronous and synchronous electric motors after overhaul. Voltage of tested electric motor, kV: from 0.66 up to 6. Capacity of tested electric motor, kW: 100-400 250-1000. Equipment installed at the station provides the following trials: - measuring winding isolation resistance in relation to the machine body and between the winding. - Measuring resistance of windings under direct current in practically cold state. - Trials under increased frequency of rotation. - Electric stability testing of winding isolation in relation to machine body and between the windings. - Electric stability testing of winding interloop isolation. - determination of idle running current and losses; - determination of short circuit voltage and losses; - Determination of transformation ratio (for machines with phase rotor). - Idle running. - Determination of idle current for synchronous machines.
