The objective of this project is to develop an improved surge protector to limit the transient voltages on cable sheath circuits, using the superior non-linear resistance characteristics of metal-oxide ceramics. To assess the transient voltages and the requirements of a metal-oxide protective device, a detailed analysis was carried out using digital simulation techniques. Field measurements, before and after the installation of surge protectors, were then carried out to verify the analytical results.
