【正文】 ring the investigation, the winding is excited with different impulse waves and the potential to ground along with time of occurrence for the coils and potential across the coils with time of occurrence is observed at different parts of the winding for the Simulink based model. The response of the Simulink based model is studied with low resistance with special reference to the tap windings during open end condition (0% tappings) and when the tap windings are in series with the actual winding (10% tappings) against impulse voltage waves. The characteristic curve showing the variation of maximum voltage to ground and their time of occurrence along the winding and variation of maximum voltage across the coils and their time of occurrence along the winding with applied full voltage, chopped impulses at 3 181。s and 15 181。s, 8 181。s, pulsed wave and two impulse waveforms varying in time to chop with damping oscillations for 0% tapping.A parative study has been done on the surge response of the coils and the observations are tabulated in Table I.In Fig. 2, (A) and (B), the characteristic curve shows the variation of maximum voltage to ground and their time of occurrence along the winding with applied full voltage,chopped impulses at 3 181。s and 15 181。s, 8 181。s, pulsed wave and two impulse waveforms varying in time to chop with damping oscillations for maximum potential to ground with time of occurrence and 10% tapping. The observations are tabulated in Table II.In Fig. 3, (A) and (B), the characteristic curve shows the variation of maximum voltage across the coils and their time of occurrence along the winding with applied full voltage, chopped impulses at 3 181。s and 15 181。s, 8 181。s, pulsed wave and two impulse waveforms varying in time to chop with damping oscillations for maximum potential across the coils with time of occurrence and 0% tapping. The observations are tabulated in Table III.In Fig. 4 (A), (B) and (C), the characteristic curve shows the variation of maximum voltage across the coils and their time of occurrence along the winding with applied full voltage, chopped impulses at 3 181。s and 15 181。s, 8 181。s, pulsed wave and two impulse waveforms varying in time to chop with damping oscillations for maximum potential across the coils with time of occurrence and 10% tapping. The observations are tabulated in Table IV.III. INFERENCES1. The maximum potential to ground is observed along the mid winding coi
