UFES solutions - switchgear upgrades for rapid arc faultInnovative arc flash mitigation in less than ms: the highest possible level of arc flash protection for personnel and equipment, maintenance of secure power supply and the reduction of production stoppages. The occurrence of an arc fault, the most serious fault within a switchgear system, is mostly associated with extremely high thermal and

“Arc Flash” vs. “Internal Arc Resistance” – A tale of two terms-- &#; An internal arc fault is one that occurs inside switchgear. The internal arc resistance of switchgear denotes its ability to withstand arc faults. And, should an arc fault occur, to contain it within a single compartment in the cubicle and divert the hot gases away from personnel. To that end we put switchgear through arc-fault tests.

Rules / PPE Requirements > Arc Flash - Power Tech Workers may also be exposed to arc flash hazards when performing day to day switching operations on high energy devices. The effects of these hazards range from mild sensations, to injury, to death, and property damage. An arc flash (also known as arc blast) is a sudden, explosive electrical arc that results from a short circuit through air.
