Oil dielectric test set is used to measure dielectric strength (breakdown voltage) of transformer oil and other insulating oils. Testing voltage is up to 80kV or 100kV at user's option. Generally, it is recommended to calibrate the test set once a year according to actual situation. Our voltage divider is specially designed and made for this purpose of calibration. Easy installation and operation. Calibration value is shown in digits, which is much more intuitive (direct-view) than pointer type calibration equipment. Meanwhile, its price is economical. It is widely used by electric power department and measure department.
