Product features:
1. Equipped with high-voltage voltage, low-voltage current, zero position indication, power indication, work 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 current relay has a wider timing range (1S-99H), which is more accurate and reliable, ensuring personal and equipment safety.
3. The high-voltage coil of the test transformer is a cylindrical multi-layer tower type, wound with high-quality polyester enameled wire and high voltage insulation material.
4. Adopting a combination of hardware and software anti-interference technology, it has stable performance and strong anti-interference ability. The entire product is characterized by light weight, small size, convenient movement, and superior performance. Not affected by harsh weather conditions, on-site transportation does not require static 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 tested object and discover insulation defects of the tested object.
6. The test transformer is equipped with capacitors of the same voltage level and capacity, silicon stacks, and high-voltage DC microampere meters, which can be assembled into a DC high-voltage test device and can measure high-voltage DC leakage current.
