Product Overview

TDM AC/DC Test Transformer is a new type of high-voltage testing equipment. This series of products adopts a single-frame core-type iron core structure, with the primary winding and high-voltage winding coaxially wound on the iron core, thereby reducing leakage flux and increasing the coupling between windings. The overall structure of the product is compact, with strong versatility and easy portability. It is suitable for power systems and power users to test the insulation performance of various high-voltage electrical equipment on site, and is an essential test instrument for power equipment testing and preventive tests.

In addition to AC power frequency withstand voltage tests, if equipped with capacitors, silicon stacks, and high-voltage DC microammeters of the same voltage level and capacity, it can be assembled into a DC high-voltage test device to measure high-voltage DC leakage current.

TDM AC/DC Test Transformer is a new type of product produced after improvement based on the same type of product YDJ (G) high-voltage test transformer, in accordance with the test transformer national standard ZBK41006—89 requirements. This series of products has the characteristics of small size, light weight, compact structure, complete functions, and convenient use. It is suitable for power, industrial and mining, scientific research and other departments, and is used for power frequency withstand voltage tests and DC leakage tests on various high-voltage electrical equipment, electrical components, and insulating materials. It is an indispensable instrument in high-voltage testing.
