Abstract
Surge arresters form a critical component in the safe and reliable operation of electrical zone substations. Overvoltages resulting from a lightning strike pose the greatest risk of damage to substation equipment reaching peak values of over 100 times the nominal line voltage within microseconds. During such overvoltage events, the surge arrester limits the level of voltage that the equipment is subjected to, thus providing protection to very expensive, and specialised electrical infrastructure.
Correct arrester specification is the first step in determining the type of surge arrester required for each installation. A second, but no less important step is determination of its physical location and connection method. The distance a surge arrester is located from equipment is a significant factor in its ability in protecting equipment.
Through the undertaking of this detailed research project, optimum arrester location, connection methods and insulation co-ordination derived from software simulation will be compared to standard design principles utilised by Essential Energy (EE) and verified using equivalent circuit analysis.
