Abstract :
A-C DIELECTRIC-LOSS TESTS: TEST TECHNIQUES based on dielectric measurements at operating frequency, originally developed for higher voltage insulations, have been applied to the insulation of generator coils. The volt-ampere requirements of the test voltage source may be reduced materially by resonating the capacitance of the generator winding with a variable high-voltage inductor.
