Based on the method of moment (MOM) and marching on-in-time method (MOT), a new method to solve the time domain integral equation (TDIE) was put forward, which can be used to investigate the transient response of the complex electrical networks and those with lumped parameters electrical element effectively. With the axial currents on the metal conductors taken as unknown variables, and the piecewise...
A simulation model of a 180 turns continuous disc type transformer winding was used to study the propagation characteristics of partial discharge (PD) based on multiconductor transmission line (MTL) theory. In order to obtain distribution parameters of unit length of windings, two 2D axial symmetric finite element(FE) models are set up under ANSYS environment. The electromagnetic FE model is used...
In order to investigate the propagation of partial discharge pulses in transformer winding, the simulation model of a 180 turns continuous disc type transformer winding based on multi-conductor transmission line (MTL) theory is constructed. According to the symmetry of windings, a 2D equivalent finite element model is set up under ANSYS environment. A modified method is proposed to calculate the K...
