Abstract

The paper is based on closed form analytical solution for switching overvoltages obtained bys-domain techniques. The sequential closing of the switch poles energizing a transmission line is reflected in expressions of the open-end voltagesin terms of time and three parameters related to the moments of switchingThese functions are then maximized by constrained optimization techniques.
