Abstract :
The proposed 345-kV transmission system interconnecting three Texas utility companies was studied for overvoltages due to switching surges-and resonance. The results of the study are presented and evaluation is made of the effects of nontransposition of the lines, close coupling of parallel lineson the same tower right- of-way, and the presence of compensating reactors under particular circuital configurations. The means for carrying out the study was provided by a general purpose analog computer equipped with peripheral transport time-delay components allowing the simulation of traveling wave phenomena.
