Arc Flash Analysis

A study investigating a worker ’s potential exposure conducted for the purpose of injury prevention and the determination of safe work practices and appropriate levels of PPE.
Arc flash

An electrical arc is formed any time there is an insulation breakdown between phases or ground. It could happen when no one is around, someone walking in proximity, or someone working on the equipment. The most hazardous situation is when someone is working on or near energized equipment. They probably have the equipment doors open and are in close proximity to the equipment. When an electrical worker, while working inside an energized electrical panel, makes contact between phases or phase and ground with a conductive object like a screwdriver, or body parts, an electrical arc can form.

Electrical Hazards

The electrical arc creates a pressure wave. The incident energy is the energy of this arc-flash coming into contact with a surface. Essentially an electric arc creates a radiation burn which accounts for the internal burns a person can receive when exposed to an electrical arc flash.

Arc Flash Hazard

An Arc-Flash Hazard Analysis starts with gathering up-to-date equipment information, then performing a detailed analysis comprised of a load-flow study, short circuit study, and protective device coordination study as well as an equipment evaluation to determine that the current withstand rating is acceptable. Most up-to-dateWhen the arc-flash hazard label is put on the equipment, you can sleep better at night if you know the arc-flash study was performed with the information and methods.

Arc Flash Analysis Services

NFPA

Incident energy and arc-flash boundaries are calculated following the NFPA 70E or IEEE 1584 Standards.

Fire safety

Fire safety measures can be taken by NFPA standards. NFPA 70E provides the formulas and tables needed to solve for the incident energy. IEEE 1584 provides techniques for SEOers & operators in determining the arc flash Hazard distance and incident energy.

Arc flash for Industries

SVT completely studies the system Design and undergo the ArcFlash Hazard Analysis and gives necessary different boundary points like Flash Protection Boundary, Limited Approach Boundary, Restricted Approach Boundary.
