The Transient Network Analyzer is used to determine the maximum magnitude and duration of transient and sustained overvoltages which can occur on a system during any change of state. Where a change of state may be the energization or deenergization of a line by operating a circuit breaker, the occurrence of a fault condition or a sudden loss of load. These overvoltages are then used to establish equipment needs and duties, design alternatives which meet these requirements and establish acceptable operating procedures. With these established, the transient voltage magnitudes are then used to establish the transmission line Basic Insulation Level and the minimum lightning arrester requirements, which in turn establish the station Basic Insulation Level (B. I. L. ).
