Intelligent transformer as an important part of intelligent substation, can be flexible and controllable and can real-time monitoring, protection, control transformer normally. online monitoring is the guarantee of realization of intelligent transformer, Partial discharge on-line monitoring optical fiber temperature measurement, casing medium on-line monitoring, winding on-line monitoring are the most important three aspects. The commonly used methods of Partial discharge on-line monitoring, a pulse current method, UFH method, gas chromatography, and ultrasound. The analysis of necessity of the main transformer partial discharge on-line monitoring configuration, and the fiber winding temperature online monitoring configuration. |
