Bonding requirements for conductive poles

摘要

Increasing load density at electric utilities has driven the trend toward larger distribution conductors and higher settings on overcurrent protective equipment. Not only are pickup values of feeder breakers and reclosers increasing, the protective curves are often slower to achieve coordination with downstream devices. Where there are larger conductors and slower protective settings you will often find more application of conductive distribution poles to carry the structural loads imposed by larger conductors.
