The Pressure of the transformer winding has an important influence on the short circuit ability of the transformer. Keeping a constant pressure is helpful to improve the short circuit withstanding ability of the transformer. We provided a fiber Bragg grating pressure sensor that can monitor the pressure on line, which has not been realized before.
The fiber Bragg grating force sensor can monitor the winding compacting force during the transformer oil injection and the operation of the transformer with security, stability and high precision, and provide support for transformer manufacturing design and process improvement.
