Product features
This set of non-discharge frequency power supply is mainly used for AC withstand voltage test and partial discharge test of equipment. By using the excitation transformer to excite the series or parallel resonance device circuit, the output frequency of the frequency power supply is adjusted, so that theductance L of the reactor and the capacitance C of the test sample in the circuit resonate, and the required voltage is generated on the test sample; or through intermediate transformer directly output to the primary of the transformer for induction withstand voltage test.
