- This article presents a mathematical model by which the transient behaviour of an induction motor with a winding fault can be successfully analyzed. Traditional models of electrical machines are based on electrical circuit equations and equations of motion (so called mechanical circuit model). Mathematical model of induction motor described in this way is composed of differential and algebraic equations. Generally, it is an arrangement of high order set of equations containing nonlinear functions. Motor's parameters that occur in the mentioned case are hard to identify, which is the reason that the model is extremely hard to use directly. The squirrel cage motor was chosen for further investigation. The model was prepared in the ATP - EMTP simulation program. Included simulation results show its fundamental properties. It can be seen that it is a tool handy to use, enabling an easy way to obtain the simulation results by any given conditions. In the following stages the ground fault model is presented and described in detail. Included examples demonstrate basic characteristics of the proposed model and its application for internal fault analysis in the complex system included motor, load and a supplying network.
