Abstract: Surface vibration of power transformer tank was closely related with transformer windings and core. Tank surface vibration signal analysis method was one of the effective ways to monitor the power transformer windings and core condition. Combined with 500 kV substation in North China, based on the analysis of the measurement object, power transformer monitoring system principle and function was introduced based on the vibration method, the substation monitoring system were designed and constituted by controlled management, communication layer, online monitoring layer, the formation of the transformer vibration measurement system for vibration signal analysis with the practical application have certain Guiding significance.

 

Keywords: Transformer, Vibration, Sensor, Measuring system, On-line monitoring.
