Application
The power frequency no - partial discharge withstand voltage test device is a special testing instrument used to generate power frequency high voltage and conduct a decisive assessment of the insulation strength of electrical equipment. It is a key device for inspecting whether the insulation performance of equipment meets the operation requirements.
It is used to verify the insulation strength of products such as transformers, circuit breakers, high - voltage switches, power cables and motors.
Before the newly installed power equipment is put into operation, it is used to check whether the insulation is intact after transportation and installation.
It assesses the ability of insulation components such as insulators and bushings to withstand power frequency overvoltage.
It conducts regular insulation supervision on key equipment in operation to identify potential hazards.
Main Features
It can output continuously adjustable power frequency AC high voltage, ranging from tens of thousands of volts to hundreds of thousands of volts, to simulate the power frequency overvoltage condition in the power system.
When the insulation of the tested object is broken down, the device can automatically and quickly cut off the output and issue an audible and visual alarm to effectively protect the device from damage.
It displays the applied high voltage value and the current value flowing through the test sample to monitor the insulation state.
It sets the current protection threshold, and automatically cuts off the high voltage when the leakage current exceeds the limit to prevent the expansion of test sample defects.
It sets the withstand voltage test time, and automatically reduces the voltage to zero when the time is up.
