ABSTRACT:
A high voltage substation level surge suppression system is disclosed comprising three primary elements. Two surge arrestors are used, separated by a surge interceptor. The first surge arrestor encountered is a high energy dissipater. It conducts most of the energy from a lightning induced or other fast rising high voltage surge to ground. The surge interceptor, comprises an inductor formed by wrapping insulated wire around a tube through which is inserted a parallel high energy resistor. The inductor element in the Surge Interceptor operates to delay the fast rise surge or transient long enough that the high energy dissipater can operate. The resistor element operates to dampen ringing or oscillations caused by the interaction between the inductor and a high voltage lightning strike and to dissipate some of that energy. Finally, the second arrestor, the voltage controller, operates to clamp the voltage after the Surge Interceptor to a set level. Additionally, right angle turns are introduced into the circuit that exploit lightning induced surges' reluctance to negotiate the right angle turns due to the surges' high inertia.
