The instrument is easy to operate, and the measurement process is controlled by a microprocessor. As long as the appropriate measurement method is selected, the data measurement can be automatically completed under the control of the microprocessor.
Ø Integrated model, equipped with standard capacitors and high-voltage power supply for easy on-site testing and reducing on-site wiring.
Ø The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, only a standard oil cup and a dedicated testing line are needed to achieve oil dielectric loss measurement.
Equipped with CVT testing function, it can achieve self-excited testing of CVT without the need for external accessories. Only one measurement is required to measure the capacitance and dielectric loss of C1 and C2. Can achieve CVT ratio testing.
The reverse wiring test adopts IVDDV technology, eliminating the previous phenomenon of unstable reverse wiring data.
Ø Equipped with reverse wiring low-voltage shielding function, C11 can perform 10kV reverse wiring dielectric loss measurement without disconnecting the wire when the 220kV CVT bus is grounded
Ø It has the function of measuring high voltage dielectric loss and can use high-voltage transformers or series resonance to conduct dielectric loss tests exceeding 10kV voltage.
Ø Grounding protection function: When the instrument is not grounded or poorly grounded, it will not enter the normal program and will not output high voltage. The overcurrent protection function ensures that the instrument is not damaged in the event of a short circuit or breakdown of the test sample.
Ø Electric shock protection function: When the instrument operator accidentally gets an electric shock, the instrument will immediately cut off the high voltage to ensure the safety of the test personnel.
