Description

technical field [0001] The invention relates to the technical field of electrical testing, in particular to an electrical testing device used for transformer state simulation. Background technique [0002] In recent years, with the development of smart grid technology and information technology, a large number of substations have been put into operation. In order to ensure the safe, economical and stable operation of electrical equipment in the power system, it is necessary to conduct various electrical tests on power equipment at any time according to operating conditions. , to grasp the health status of the equipment through the test results, which requires the test technicians not only to be familiar with the test procedures, but also to adopt scientific test methods and means, and to have correct analysis and judgment capabilities. However, the general high-voltage electrical test requires the test personnel to perform on-site operations, which is dangerous, and the high...
