Possibilities of program EMTP - ATP to analyze the starting current of induction motor in frequent switching

Program EMTP ATP is a very effective tool for solving and analysis of transients of various electrical circuits. We used this program for analysis energy stored in inductance of induction motor and the influence to starting current. Paper deals with the situation repeating the induction motor starting, that occurs immediately follow each other. During such repeating induction motor starting the influence of already existing magnetic field in the motor is applied. Is is caused by energy stored in main inductance of induction motor. We performed a simulation in EMTP ATP and after that we made measurement.
