transformer testing machine

 

This tester adopts modern technology to achieve automatic frequency conversion, analog-digital conversion and calculation, features strong anti-interference ability, fast test speed, high precision, automation, easy operation. Its high-power switch supply can output 45Hz and 55Hz pure sine wave, boost automatically with voltage up to 10kV. As the power frequency disturbing can be eliminated, it is suitable for field test in power plants or other places with strong electromagnetic interference, now widely used for dielectric Loss factor (tgδ) measurement of transformer, bushing, capacitor, arrester and other equipment.

 

Features

1. Complex number current method to measure capacitance, tgδ, and other parameters. Auto, High accuracy

2. Reliable measuring data in heavy electromagnetic interference environment

3. Large screen LCD display, menu prompts, easy reading and easy operation
4. Microprocessor control, auto measurement ( after choose measuring methods)

5. Compact structure with standard capacitor and high voltage power supply inside, easy wiring.
6. High accuracy, oil dielectric loss measurement to be done by matching with oil cup and test lines

7. CVT self-excited test function, one time measurement to get C1, C2 capacitance and dielectric loss
8. Grounded specimen test adopts ivddv technology to get stable measurement data
9. Low-voltage shielding function, when 220kV CVT bus is grounded, C11 can be disconnected for 10kV GST

10. HV (+10kV) dielectric loss factor test function ( after match with HV transformer or resonance devices)
11. Grounding protection function, over current protection function

12. Electric shock protection function, auto cut off power when operator accidentally get an electric shock.
