Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a transformer load box calibration device. Background technique [0002] The transformer load box is a multi-value measuring instrument that provides an analog load for the calibrated transformer when calibrating the current or voltage transformer. The rapid development of the national economy has made the demand for electric power more and more large. The stability and reliability of the electrical measurement transformer are very important in the control of the electrical measurement process. As a transformer load box calibration equipment, the traditional transformer load box detection equipment is bulky, complicated, inconvenient to operate, and cannot meet the requirements of industrial sites. [0003] With the extensive use of transformer load boxes, the calibration work of transformer load boxes is also increasingly intensified. The traditional method uses a ...
