Remote electronic carrier equipment is sometimes placed next to or in close proximity to commercial power substations. These types of installations include digital loop carrier, DSL and fiber mux equipment. During a line to ground fault produced ground potential rise, electronic carrier systems in close proximity of the substation, may suffer damage to their DC rectifiers from fault currents that “rise” through the grounding systems of the remote electronic carrier cabinet.
This session will discuss protecting remote electronic carrier equipment using AC isolation technology for any location that is placed next to or in close proximity to commercial power substations.
Discussion will also be held on: Remote Electronics (RE) cabinets (DSL, Fiber, and DLC) placed in close proximity to power substations and the resulting damage to their power supplies; Ground Potential Rise (GPR) as it relates to these (R E) cabinets; the basics of AC Isolation technology: and the results of AC isolation on these (RE) cabinets during a power line fault caused GPR.
