Arc Flash Analysis with EA-PSM software :
Explosive energy released during arcing faults is the cause of injuries to workers from burn.There have been deaths reported at workplace due to accidents caused by electrical faults, roughly 50% were related to arc flash. Most of these workers were not properly warned of the magnitude of arc flash. Although injuries are not as frequent as other job-related injuries, their severity makes the cost to human life and industry much greater. The monetary cost is very large for medical expenses, equipment replacement, downtime, and insurance costs.

The potential for arc flash has existed as long as plants have been powered by electricity.

There are two factors that have made arc flash a focus:

1. A greater understanding of arc flash hazards, and the risks they pose to personnel. Research into arc flash and arc blasts has begun to quantify the powerful forces they unleash.
2. Increased vigilance on the part of OSHA. OSHA is using the requirements of NFPA 70E, the industry’s consensus standard for electrical safety, to judge whether the employer “acted reasonably” in protecting its workers from arc flash hazards. Noncompliance can result in substantial fines to employers.

Harmonic Studies Analysis Service is performed to determine harmonic distortion levels and filtering requirements within a facility and to determine if harmonic voltages and currents are at acceptable levels. Field measurements and computer simulations are used to characterize adjustable-speed drives (ASDs) and other nonlinear loads and simulations are then performed to determine the filter specifications and effectiveness. The application of harmonic filters will significantly alter the frequency response of the power system. An evaluation of the harmonic voltage and current limits (e.g., IEEE Std. 519) is completed to determine the effectiveness of the proposed filter installation.


Why are Harmonic Studies important?

• Avoids damage due to excessive harmonic currents in transformers and capacitor banks.
• Ensures sensitive electronic equipment will not malfunction due to excessive harmonic voltage distortion.
• Satisfies the utility's voltage and current harmonic distortion requirements.

 

Harmonic studies should be considered whenever there are solid state drivers or electric furnaces and capacitor banks in the power system.
