This test system is mainly used for inspecting electrical products(load charge＜2000pF)
Insulation level at power frequency and high voltage, Such as power frequency withstand voltage
test, 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： YXY-A302
YXY-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.
model: YXY-A302
Rated capacity：12kVA
Working voltage：220V
2. Digital partial discharge detector(touch screen)
This PD instrument is operated by a touch screen, and all functions are operated on the touch
screen, which not only improves its service life, but also enhances the experience. It also has the
