摘要：

The paper presents several topics regarding the atmospheric over-voltages that stress the transformer windings. In order to analyze the propagation of the over- voltage waves (lightning surges) along the transformer windings, both in space and time, the integration of equations is performed using a numerical approach by means of analog circuit simulation such as SPICE (Simulation Program with Integrated Circuit Emphasis) type. There are implemented equivalent electric circuits for both the over-voltage impulse generator and electric transformer. The parameters of the generator are determined such that the generated waveform is as close as possible to the standard waveform defined in IEC 60060-1 and -2 standards.
