IEEE Draft Standard for Grounding Practices for dc Electrification Overhead Contact Systems, Including Application of Lightning Arresters, for Transit Systems
This standard is a basis for the design and application of dc surge protection devices to assist in protecting Overhead Contact System (OCS) from transient overvoltages associated with lightning and switching surges. Switching surges are inherent characteristics of electrification system and are generally considered low energy transient overvoltages. Lightning surges are natural, caused by electri...
