Abstract:
The present theaia describes the behaviour of transient currents,, voltages and torques in Induction motor at switching.
The work has been daaided in to two parts,
i) Switching transients in single-phase Induction motor (Capacitor start) .
ii) Switching transients in three phase Induction motor started on single-phase supply,
To predict the transient behaviour of particular motor the transients currents of motor at starting have been calcul. ated and the result vatified by actual records of transient currents.
All the values have been normalized so that the results can be utilized for the class of motors which is represented by the motors on which the present study has been marls,
The difference between the calculated and experia -ntal results is found to be with in reasonable limits ni eYx iri-
omental error.
