The fully automatic non partial discharge withstand voltage test device is suitable for power distribution systems, power transformer manufacturers, industrial and mining enterprises, scientific research departments, etc., to conduct insulation strength tests on various high-voltage electrical equipment, electrical components, and insulation materials under power frequency or DC high voltage.

Widely applicable for measuring partial discharge of various high-voltage electrical products such as transformers, transformers, high-voltage switches, zinc oxide lightning arresters, power cables, etc., conducting type tests on products, and supervising insulation operation. This instrument has high detection sensitivity, a wide coverage of sample capacitance, a wide range of applicable test samples, complete input units (detection impedance), and multiple frequency band combinations (nine types). After appropriate calibration, the instrument can directly read the discharge amount of the discharge pulse.

Full Chinese interface, simple and clear operation, adaptable to various usage scenarios

Light touch button operation, all functions can be set through the button, improving the safety and reliability of the product

Adopting a combination of hardware and software anti-interference technology, with fluctuating functionality and strong anti-interference ability

Pause function: During automatic control, this function can pause the pressure rise or fall at any point. The pause time can be sensitively controlled by the experimenter, making it easy to observe the shape of the test sample

Automatic timing function. When the voltage automatically rises to the set value during automatic control, the equipment automatically starts timing. When the timing time is up, the experimental consequences are displayed, and the equipment automatically returns to zero
