This test system is mainly used to test the insulation level of electrical products (load charge <2000pF) under power frequency high voltage, such as power frequency voltage test, partial discharge test. The complete set of equipment includes local discharge/withstand voltage measurement and control system, digital correction pulse generator, input unit, power frequency halo free test transformer, coupling capacitor without local discharge, protection resistor without local discharge, electric voltage regulation isolation filter device, etc.

The entire device must be used indoors, the power supply grid voltage is 380V, there is a good and dedicated grounding system, grounding resistance value <1Ω, the smaller the better

1. Power frequency high voltage test console
Model: KDYDJ
KDYDJ power frequency test console adopts LCD screen to display parameters, measure the input voltage, input current, output voltage and output current of the test transformer, the measurement accuracy error is less than ±1%, which can effectively protect the abnormal conditions such as overload, overcurrent, short circuit and flashover in power frequency high voltage test.
◆ LCD display;
◆ The overcurrent protection value of the transformer input current and output current can be set;
◆ With manual button lifting pressure and electronic knob automatic lifting pressure two modes of pressure regulation; The automatic lifting pressure value can be reached by a key after setting;
◆ Serial communication, connected to MES and ERP system, can upload data. Model: KDYDJ
Rated capacity: 20kVA
Working voltage: 220V;2. Digital partial discharge detector part (full touch screen)
The instrument adopts touch screen operation, all functions are implemented on the touch screen operation, which not only improves its service life, but also enhances the sense of experience, but also has the following advantages and functions:
◆ Touch screen operation
