This product (hereinafter referred to as YDJ type power frequency AC withstand voltage test complete set device) is a new type of product produced based on the TDM (G) series lightweight AC/DC high-voltage power frequency AC withstand voltage test complete set device, which has been greatly improved on the basis of the original similar products according to the standard of the Ministry of Mechanical and Electrical Engineering "Power Frequency AC withstand voltage test complete set device". This series of products has the characteristics of small size, light weight, compact structure, complete functions, strong universality, and convenient use. Especially suitable for conducting insulation strength tests on various high-voltage electrical equipment, electrical components, and insulation materials under power frequency or DC high voltage in power systems, industrial and mining enterprises, scientific research departments, etc. It is an essential and important equipment in high-voltage testing.

Product characteristics

The 50kV 5kVA AC And DC Hipot Tester is an upgraded high-performance testing device derived from TDM(G) and YDJ series platforms, perfectly compatible with the functional advantages of both series and optimized for on-site detection efficiency and multi-scenario adaptability.

The device integrates AC power frequency withstand voltage and DC high-voltage leakage test functions in one, and is specially developed for insulating medium detection while undertaking conventional high-voltage equipment insulation tests, which can realize professional dielectric oil testing with high accuracy and stability.

It has excellent expansion performance, with built-in 200V series taps supporting multi-unit cascade for higher voltage output, and customizable 5-15kV medium-voltage taps, which can match the testing requirements of different types of power equipment and insulating oil samples.

With high test precision and reliable data feedback, the device can provide standardized detection support for power transformer oil testing and electrical transformer oil testing in power system operation and maintenance, filling the gap of integrated testing of equipment and insulating medium.

As a specialized high-voltage testing instrument for power, mining and scientific research fields, it is a key supporting device for improving the comprehensiveness of high-voltage preventive tests and ensuring the safe operation of the whole power equipment system and its insulating medium.
