Abstract:
In this thesis an attempt has been made to calculate switching surge overvoltage using Laplace transform technique.
The merits and demerits of various methods for the calcu-lation of switching surge overvoltage, namely, field tests, analog and digital techniques, have been discussed in Chapter-I.
A comparative study of different digital techniques has been made in Chapter-II. subsequently an indepth study of the Laplace transform technique and its application towards
(i) unloaded line energization~
(ii) energization of resistance loaded line,
(iii) energization of inductance loaded line, om. Case study of a system for various line conditions has
been done and simulated on DEC-2050 Computer System in FORTRAN-IV
(a listing of program is given in Appendix-II).The results obtained have been plotted on CALCOM plotter, and are given in Chapter-V. The concluding chapter, namely Chapter-VI, discusses the future scope of work in the related field.
