HZZJ-H Current Transformer CT Calibrator Verification Device

I. Overview

HZZJ-H type current transformer CT calibrator verification device is our company to suitable for all levels of metrology institutes, electric power institutes to verify the transformer calibrator. The new product developed by the rapid and convenient verification of the instrument is suitable for the calibration of the transformer calibrator at all levels of measurement institutes and electric power institutes. With digital composite power supply, the output is stable and the distortion is small. The instrument adopts self-calibration technology, which can correct the output in real time, and the test range is large. The current and voltage can reach 200% working point, which is very suitable for the power metering department.
The device is equipped with a wealth of software operation functions. The calibration and calibration of all calibrators can be directly controlled by the computer. For the open-end transformer calibrator, the data can be collected automatically, for automatic functions and ranges. The switched calibrator can perform continuous automatic calibration and verification, directly forming the verification report and calibration certificate, in line with the latest JJG169-2010 regulations and new uncertainty requirements.
