GIS vibration principal analysis and modeling

Based on the most basic electromagnetic theorem, this paper analyses the most basic principle of GIS vibration formation. The characteristic formulas of magnetostriction and Ampere force vibration are deduced, and the characteristic frequencies of them are both 100Hz. Combined with the structural characteristics of GIS, this paper analyzes the two common vibration models of induced eddy current and induced circulation, and calculates their analytical formulas, which can easily calculate the induced current, and provides a reference for GIS vibration research.
