This article concerns reliability assessment of an electricity distribution substation surge protection system, composed of surge arresters. For this purpose a reliability analysis is performed and also a surge protection system reliability mathematical model is suggested. Based on it mathematical formulae are worked out intended for practical calculation of proper reliability indices values. The...
The operating voltages of low-voltage control circuits in power stations and substations have become lower with the installation of digital control equipment. This significantly increases the risk of faults and malfunctions of the circuits resulting from overvoltages in the control circuits due to lightning and switching surges. Therefore, the characterization of such overvoltages is required to protect...
Grounding practices that have generally been accepted by the electric utility industry as contributing to effective grounding systems for personnel safety and equipment protection in generating stations are identified. A guide for the design of generating station grounding systems and for grounding practices applied to generating station indoor and outdoor structures and equipment, including the interconnection...
