Features
The use of frequency conversion technology can ensure accurate measurement under strong electric field interference.
This instrument can be used to measure high-voltage electrical equipment that is not grounded or directly grounded using forward and reverse wiring methods.
Can measure the tg δ of capacitive voltage transformers and the capacitance of main capacitors C1 and C2.
The instrument is equipped with a high-voltage boosting transformer inside, and safety protection measures such as zero crossing closing and lightning protection are taken. The operation is simple and safe.
