Product Description

GDYD-55A 50kV Automatic AC DC Hipot Test Set 

I. General information

GDYD-55A Automatic AC/DC Hipot Test Set is composed of automatic control unit and AC/DC oil testing transformer (HV unit) which output AC and DC voltage smoothly. Meanwhile, it has many monitoring and protection functions.


II. Features
 

1. 7inch color LCD screen, with PLC automation control.
2. HV Voltage, LV voltage, LV current measured at the same time, with high precision sensor and high-performance collection chip

1. Automatic mode and manual mode for option.
2. Display HV voltage, LV voltage, LV current, time and withstanding result.
3. Over-voltage and over-current protection. Output voltage, HV current upper limit, LV current upper limit and timing can be set.
4. Zero-starting function. Test can be proceeded after the voltage is back to zero.
5. Store up to 8000pcs data in 3months. It has USB port to upload data to USB disk.
6. When setting voltage is arrived, it will be timing automatically. After timing, voltage will be back to zero.
7. When the LV current is over setting value, the voltage will be cut off automatically and it will be back to zero. When the HV current is over setting value, the test object will be cut off and test can be proceeded continuously.
8. With anti-interference ability, suitable for electromagnetic environment.
9. With wheels for both control unit and HV unit, easy to move.
