Arc Flash Study and Analysis

We offer arc flash analysis program and provide arc flash analysis report  for safety and efficiency of power systems. Arc Flash Study and Analysis was first introduced by IEEE about a decade ago.

An arc flash is the light and heat produced during an arc fault. It happens when current flows through air gap in between conductors. Arc flash causes ionization of air and expels large amount of energy. The arc flash temperatures can reach upto 35,000 degrees farenheit and that is hotter than the surface of the sun.

Objective 
The Purpose of Arc Flash Hazard Study and Analysis 

The purpose of the arc flash study is to determine the protective clothing requirements for persons working on live or electrically energized equipment (whenever feasible and possible).

• Determine the risk of personnel injury as a result of exposure to incident energy (IE) released during an arc-flash event
• Provide reduced incident energy exposure if possible by using alternate protective device settings
• Provide recommendations for appropriate arc-flash hazard protection
• Comply with OSHA, NEC, and NFPA 70E requirements

WHO NEEDS ARC FLASH HAZARD STUDY AND ANALYSIS?

Most commercial, institutional, and industrial electrical systems are prone to arc flash hazards. OSHA requires that those systems be individually analyZed and, if hazards exist, labelled to identify the arc flash boundary. This will increase personnel safety, reduce shock hazards and reduce arc flash injuries. We provide arc flash studies using the Arc Flash Analysis software ETAP.

Working within NFPA and IEEE guidelines, our experienced power systems engineers will perform accurate systematic Arc Flash Hazard Analysis to:

• Protect electrical workers from injuries due to arc flash.
• Determine the Flash Hazard Boundary.
• Determine the PPE needed to minimize the possibility of injury due to arc flash.

CERTIFICATION & REPORT 

ARC FLASH STUDY AND ANALYSIS REPORT

Upon completion of the arc flash analysis program calculations, we will prepare your Arc Flash study Report. This will be provided to you for a short review period, during which your team can evaluate modifications. At this point, we can hold meeting to deduce the report results. Upon approval, we will provide a final report and full sized one-line diagrams, stamped by our Registered Professional Engineer. The drawings and report will also be supplied to you in a digital format.

BENEFITS

BENEFITS OF ARC FLASH HAZARD STUDY & ANALYSIS

The Arc Flash Analysis program offers following benefits:

• Design safer power systems while applying the NEC 110.16, OSHA, NFPA 70E, IEEE 1584 and NESC standards or requirements.
• Save time with the fully integrated Short Circuit, Over-Current Coordination, Equipment Evaluation and Arc Flash Evaluation modules working together with libraries of clothing levels, protective devices and bus ratings.
• Provide a safer working environment by specifying the proper level of clothing. Wearing inadequate clothing is dangerous for obvious reasons, but wearing too much clothing is dangerous due to limited mobility and visibility.
• Evaluate alternatives quickly and easily to establish an optimal design.
• Improve safety margins with user-definable arcing fault tolerances.
• Save time by automatically generating arc flash labels and work permits.
• Avoid potential fines, lost productivity, and increased insurance and litigation costs.
