The paper introduces a type of the turn-to-turninsulation test equipment including an impulse-voltage generator and a peak voltmeter for the electrical machine pole coil.
With the parameters of a real dry-type air-core reactor, the emulation analysis verifies that the impulse-voltage method is suitable to test its turn-to-turninsulation.
