This product is a basic testing equipment used by users such as power plants, power supply bureaus, and research institutions for conducting AC withstand voltage tests. It is used to test the insulation strength of various electrical products, electrical components, insulation materials, etc. under specified voltages, assess the insulation level of the product, detect insulation defects of the test object, and measure the ability to withstand overvoltage.

1. Equipped with high voltage, low voltage current, zero position indication, power indication, working indication, and timing indication; Functions such as overcurrent protection, zero start protection, sound and light language alarm reminder, etc.
2. Adopting a new type of time relay, the new type of current relay has a wider timing range (1S-99H), more accurate and reliable, ensuring personal and equipment safety.
3. The high-voltage coil of the test transformer is a cylindrical multi-layer tower, made of high-quality polyester enameled wire and high voltage insulation material.
4. Adopting a combination of hardware and software anti-interference technology, the product has stable performance, strong anti-interference ability, light weight, small size, easy mobility, and superior performance. Not affected by harsh weather conditions, on-site handling does not require standing still for testing.
5. It can be used for AC and DC withstand voltage tests of electrical primary equipment under specified voltage, to assess the insulation strength of the test sample and discover insulation defects of the test sample.
6. The test transformer, equipped with capacitors, silicon stacks, and high-voltage DC microamperes of the same voltage level and capacity, can be assembled into a DC high-voltage test device, which can measure high-voltage DC leakage current
