Let us compare crosslinked polyethylene (XLPE) and ethylene propylene rubber (EPR) as insulating materials for high voltage (HV) cables. Both XLPE and EPR have their merits, and the choice depends …
There are different protection techniques and principles. Fuses are the simplest and cheapest technology. After operation, however, fuses are required to be manually replaced to restore protection features. Protection relays …
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 …
Heat dissipation in sealed electrical enclosures is a critical consideration in the design and operation of electrical or electronic systems. Effective heat management ensures the reliability, performance, and longevity of …
Protection coordination is the heart of all power systems. To ensure a quality and reliable operation of the power systems, an electrical fault must be cleared within a short time. …
