This device is a testing equipment independently developed by our company. It integrates the merits of similar products both at home and abroad and is primarily used for testing projects such as primary busbar protection and the transformation ratios of various current transformers. Owing to the adoption of a low-power-consumption, high-capacity autotransformer and a current transformer made with high-permeability iron cores, it boasts advantages including large output power, small size, and light weight. As a result, it is widely applied in scientific research, production, and electrical testing sites of enterprises in the power, railway, petrochemical, metallurgical, mining, and other industries.
