Product Introduction
The NRJC-H insulating oil dielectric strength tester verification device is developed and produced according to the requirements of the calibration regulations of the insulating oil dielectric strength tester: Part 7: “General Technical Conditions for High Voltage Testing Equipment of the latest regulation DL_T 846.7-2016. This verification device adopts our company's patented technology of voltage divider only consumes 0.45mA AC current when the voltage accuracy reaches 0.2% and does not produce a load effect on the insulating oil dielectric strength tester.
The device consists of two voltage dividers the accuracy of the two voltage dividers is the same the A voltage divider (left) and the B voltage divider (right) can be used separately or in combination. When A+B is used in combination The displayed voltage is the sum of the output voltages of the two high-voltage transformers of the insulating oil dielectric strength tester. When used separately measure the unilateral voltage separately. Generally when doing metering calibration the method of separate calibration is used and one voltage divider is calibrated at a time. After calibrating the two sets the data of A+B is the sum.
