Fully electronic transformer calibration device
Suzhou Huadian conducts close technical cooperation with the State Grid Electric Power Research Institute, specializing in the production of various standard transformers and transformer calibration devices
In the electric energy measurement device, the electron source has a very large technical advantage over the electrician source. It can be seen from the elimination of the electric meter calibration station. However, because the transformer testing station requires much more capacity than the electric meter calibration, it is electronic The process has been slow. With the development of power electronics technology, the cost of high-power devices has fallen, making transformer detection all-electronics a reality.
