The ZCHG-12 fully automatic current transformer calibration system is a new generation of transformer fully automatic accuracy testing system developed by our company to adapt to the fast and accurate characteristics of modern current transformer calibration. The device consists of a transformer calibrator, a programmable current transformer load box, a variable frequency power supply, and a high-speed transformer test bench. The operator can set the main parameters of the tested transformer, such as type, range, accuracy level, secondary load, power factor, and transformer station position, through the computer error verification management software. By transmitting and controlling through RS485, the measurement work of 12 current transformers with the same ratio can be completed at once, greatly improving work efficiency.
