At present,the non-local-discharge test power supply device is more and more applicated in the AC withstand voltage test of power equipment of 3-500 KV voltage class,such as current transformer,circuit breaker,highvoltage bushing,cable,capacitor and other power equipment. The core equipment of the oscillation wave no-office test power supply can be effectively applied in the parts of the power transformer,the voltage transformer and the like,and the requirements of the partial discharge and the induction withstand voltage test can be met. In addition,the invention can also be used for the insulation medium loss of high-voltage electrical equipment and the main power supply used for measuring the ground resistance in the grounding network.Therefore,this device can be widerly applicated and the effect is excellent. This paper analyzes the principle of power supply technology based on the oscillation wave,and probes into its practical application as well as promotion in the field of related power.
