Figure 7. Surge voltage at motor terminal.

Thus, it should be clear that a transient associated with a

cabtyre cable can be simulated well by proposed method

in co-operation with Semlyen’s line model of the EMTP.

4. Conclusion

In this paper, based on natural theory of modes meas-

urements are carried out on induction motor in steady

state condition. Based on modal measurements induction

motor model is developed for it’s used in Electro Mag-

netic Transient Program. The validity of model is invest-

tigated by practical inverter surge measurements. It is

observed using developed model the surge voltages at

motor terminals can be represented accurately. This model

can be used for different switching surge simulations.
