The parameters of the AC/DC dual-purpose test transformer are as shown in the table above. The rated DC voltage in the DC parameters is 1.4 times of the AC current and the rated DC current is 0.7 times of the AC current

1. High voltage, low voltage current, zero position indication, power supply indication, working indication and timing indication;
2. With over-current protection, zero start protection, audible and visual language alarm reminder
3. New type time relay is adopted, with a wider timing range (1S-99H)
4. The new current relay is more accurate and reliable to ensure personal and equipment safety.
5. The combination of hardware and software anti-interference technology is adopted, with stable performance and strong anti-interference
6. The high voltage coil of the test transformer is of cylindrical multilayer tower type, made of high-quality polyester enamelled wire and high voltage withstand insulation material.
7. It has the characteristics of light weight, small volume, convenient movement and superior performance.
8. The test transformer (above 5kVA) is equipped with movable iron wheels.
9. It shall not be affected by the harsh weather environment, and the test can be carried out without being static during on-site handling;
10. It can be used for AC and DC withstand voltage tests under the specified voltage of electrical primary equipment to assess the insulation strength of the tested object and find the insulation defects of the tested object.
11. The test transformer is equipped with capacitors, silicon stacks and high-voltage DC microammeters of the same voltage grade and capacity, which can be assembled into a DC high-voltage test device to measure the high-voltage DC leakage current.
