摘要
The test method of this invention is comparatively simpler without high voltages in normal default current tests, high voltages have been replaced by impulse generator employing positive and negative symmetrical voltages mixed with impulse voltages to form asymmetrical forward and reverse high voltages, meanwhile the timing for impulse voltage is flexible, the amplitudes could be continuously adjustable according to specific needs, to make test voltage exactly reach climax upon certain timing, the test is flexible and safe, to be applied to converter valves in different direct currents.
