Arc-flash analysis is required by the Philippine Electrical Code (PEC) to enhance safety for workers who may be exposed to electrical hazards. PEC mandates arc-flash analysis requirements under Section 1.3.2.1(F) …
Current transformer (CT) accuracy class refers to how precisely a current transformer can replicate the primary current in its secondary winding, within certain tolerances, under defined conditions. CT accuracy is …
Part 1 of this article, which was the cover story in the previous issue of NETA World, explored the need for high-voltage arc flash (HVAF) assessment to protect utility workers …
Arc flash assessment based on IEEE 1584 has limitations with respect to the voltage. The voltage range applicable to IEEE 1584-2018 remains unchanged at 208V through 15kV. Low voltage range …
