Equipment for dielectric loss measurement of transformers, transformers, bushings, capacitors, arresters, etc.
● Use complex current method to measure capacitance, dielectric
loss and other parameters.
● Integrated model with standard capacitor and high voltage power
supply for on-site testing and field wiring reduction.
● With reverse wiring low voltage shielding function.
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.
