Simulation of Current Transformer under Two Conditions

This paper deals with simulation of current transformer under two conditions .they are transient conditions and steady state. At first an equivalent circuit of current transformer is displayed and explained then the nonlinear mathematical model of current transformer in accordance with transformer equivalent circuit is described. The mathematical model is simulated under Matlab/ Simulink program. It is true that a current transformer with the specified parameters of measurements is simulated. The steady state and transient conditions simulation is done that transient conditions due to a sudden short circuit in the network is assumed. The results of the simulation is certified that mathematical model is too close to the real behavior of the current transformer and therefore it can be used in larger model of the power network ۲۲kv and a new method of analysis for identification and errors positioning and confirming of the theory findings.
