【Dv Power】頻率響應特性曲線的基本認識
The frequency response analysis is a powerful tool used to check the mechanical and electrical integrity of power transformers. Short-circuit faults in the power system or potentially high acceleration created during transportation can cause severe deformations of the transformer windings and mechanical construction, due to strong electrodynamic force.
