Best Practice in Lightning Protection for Distribution Systems
Best Practice 1: Tank Mounted ArresterBest Practice 2: Wildlife ProtectionBest Practice 3: Polymer-Housed ArrestersBest Practice 4: Virtual Shield with ArrestersBest Practice 5: Preventing Backflash on Underbuilt LinesBest Practice 6: Surge Capacitors & Arresters on Generator TerminalsBest Practice 7: Riser Pole ArrestersBest Practice 8: Open Point ProtectionBest Practice 9: Suspension Mounted ArrestersBest Practice 10: Double Protection from BreakersIn distribution switchgear circuits, breakers are often close to other equipment. They are also known to produce very fast rising surges that can damage more sensitive equipment. To mitigate this risk, arresters must be applied on both sides of switchgear breakers.See more on inmr techwinspd
