Ultra-low frequency high voltage generator current data is sampled directly from the high-voltage side



The ultra-low frequency high voltage generator, also commonly known as the ultra-low frequency withstand voltage test device or 0.1Hz high voltage generator, is a specialized equipment used for insulation withstand voltage tests on large capacitance power equipment. It replaces the traditional 50Hz power frequency withstand voltage test by outputting high-voltage alternating current at an extremely low frequency (typically 0.1Hz).
