Integrative test device of electric test of transformer

An integrative test device of an electric test of a transformer adopts a set of power supplies. A foreground processor including a central processing unit (CPU) system is used for data acquisition of three data acquisition systems and controls working of a relay switching system. A background computer finishes human-machine interaction work, manages data, and outputs test reports. The test device is light in weight, occupies less space, reduces troubles of climbing up and down from the transformers of operators, and enhances personal safety. The test device has the advantages of increasing work efficiency, shortening power failure time of the device, saving energy, reducing exhaust emission and protecting the environment.
