Dalian Northern Transformer Group Co., Ltd. Distribution Network Primary and Secondary Integrated Electronic Transformer Calibration

On June 12, 2017, our company's engineering technicians used the XL-809 electronic transformer calibrator (small signal input), independently developed by our company and purchased by Dalian Northern Transformer Group Co., Ltd., to test the ratio error and phase error of the Rogowski coil (600A/1V, 0.5S class) and LPCT low power coil (20A/0.2V, 10P10 class) of the primary and secondary integrated electronic transformer for distribution networks, providing a reliable basis for their product's factory debugging. During this process, our equipment's high precision, ease of operation, and excellent after-sales service were recognized and praised by the on-site testing personnel.
