This test system is mainly used for inspecting electrical products(load charge＜2000pF)Insulation levels at power frequency and high voltage, such as power frequency withstand voltage test and partial discharge test. The full set of equipment includes a digital partial discharge tester /withstand voltage measurement control system, digital correction pulse generator, Input unit, power frequency halo-free test transformer, partial discharge-free coupling capacitor, partial discharge-free protection resistor, electric voltage regulating isolation filter device, etc. The entire set of equipment is required to be used indoors, with a power supply grid voltage of 380V and a good and dedicated grounding system. Ground resistance＜1Ω, the smaller, the better.
1. Power frequency high voltage test console
Model: HY-A302
HY-A302 The power frequency test console uses an LCD screen to display parameters to measure the input voltage, input current, output voltage, and output current of the test transformer. The measurement accuracy error is less than ±1%. It can detect overloads, overcurrents, and short circuits that occur in power frequency high-voltage tests. Effective protection against abnormal conditions such as flashover and flashover.
◆LCD display ;
◆The input current and output current overcurrent protection value of the transformer can be set arbitrarily;
◆It has two voltage adjustment methods: a manual button to raise and lower the voltage and an electronic knob to automatically raise and lower the voltage. After the automatic voltage raising and lowering value is set, it can be reached with one click.;
◆Serial communication, connect MES and ERP, Data can be uploaded.
