YDJ Oil Immersed AC/DC Hipot Test Set

Product Introduction:

YDJ Oil Immersed AC/DC Hipot Test Set features a compact and lightweight design with high integration and versatile functionality. It is highly portable and user-friendly, making it especially suitable for AC/DC withstand voltage testing of electrical equipment, components, and insulating materials in power systems, industrial enterprises, mining facilities, and research institutions. This series is an essential solution for high-voltage testing applications.

Product Characteristics:

1、The high-voltage test transformer features premium material selection, ensuring reliable quality and stable performance.

2、It offers a wide voltage margin and is designed with a compact corona ring and minimal partial discharge.

3、Utilizing advanced insulation materials, the transformer achieves a compact structure and lightweight design.

Announcements 

1. Complete the circuit as you expected. The hull of testing transformer and operation system must be well connected to the ground. Testing transformer' high voltage X end and measured winding F end must bewell connected to the ground. 

2. In the cascading testing, the low voltage of second and third testingtransformer's is X end, winding F end and HV winding X end must be connected to the hull of transformer. The second and third transformer'shull must be connected to the ground through insulating frame. 

3. Before power on, the adapter must be on the “zero” and then can turn on and boost voltage. 

4. Sooth boosting the voltage through the regulator hand wheel from zero. The methods: quick rising (20s); slow rising (60s); extreme slow rising. After rising the voltage to 75％ of your target voltage, we should boost by 2％ per second until to the target one. At the same time monitor the measured equipment and instrument. In the process of boosting, if there is any abnormal phenomenon, we should cut off the power or step down the voltage at once. 

5. After testing, we should step down the voltage in several seconds to the zero and power off. 

6. This production cannot be used in the other parameter which in not allowed. Except necessity of testing, get on the power or cut off is not allowed. 

7. In the high voltage testing, not only get the operation manual familiar but also obey to the national standard.
