1. Introduction This document outlines acceptable practices for earthing and bonding electrical apparatus in hazardous areas. While the topic is straightforward, it spans multiple areas of electrical expertise, making a …
Insulation Level General Categories Selection of the appropriate insulation level for power cables depends on the phase-to-phase voltage and two general categories shown below: 100% Voltage Level. Cables in this …
Power cable shielding is crucial for ensuring safety,electromagnetic interference (EMI), and overall performance, especially at higher voltage levels. Key considerations in power cable shielding (1) Safety. Shielding helps ensure that …
What are Static Charges? Static electricity refers to the accumulation of electric charge on the surface of objects. It occurs when two materials come into contact and then separate, transferring …
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 …
