The transient response of two, three, and four series L-C loop systems is examined. The results of a case study of voltage magnification on an actual system with shunt capacitors at four different voltage levels are presented. On this system, equipment damage occurred within an industrial plant in the same time frame of the energization of a capacitor bank in a utility substation. Curves which illustrate the theoretical maximum components of the transient overvoltages and their interaction with the 60 Hz fundamental voltage in actual systems are presented.
