Electrical Safety Regulations are drafted by regulatory bodies like OSHA, IEEE 1584, NEC, NFPA 70E such that the companies and industries comply to the regulations specified and provide a safe working environment to its operating personnel.
These regulations were formulated by extensive research on Arc Flashes and other Electrical Hazards.
Arc Flash Study Requirements OSHA specify a certain operating standard to be complied without any relaxation. These regulations are modified based on the new researches complying to various practical scenarios.
IEEE 1584 2018 is one such recent amendment made on extensive research DONE on various electrode configurations, fault currents, bolted fault currents. With VB Engineering you can rest assured as we implement the Arc Flash Study Requirements OSHA in the Arc Flash Study, Arc Flash Analysis, determination of Arc Flash Hazard Analysis and complying to NEC 110 in the Short Circuit Coordination Study.
• Inherently flame retardant in nature of fabric and sewing thread
• Corrosion of the contact points, Dust accumulation leading to unwanted paths for the Arc Current. This situation arises mainly due to the reason that many of the Arc Flash protective devices are designed to operate for a specific current ratings usually the Arc ratings. This is incorporated so as to avoid their tripping for faults other than Arc Flash currents which may range about 6KA and thus avoid lines being interrupted for other electrical faults.
• Failure of Protective devices to operate. This may be due to the lack of periodical analysis carried out at the firm. NFPA 70E clearly specifies that an Arc Flash Study be evaluated for a period of every 3 years .
• Failure of the circuit breakers and other protective devices due to an absence in the upgradation of the protective equipment. NFPA 70E AND OSHA regulations specify that an Arc Flash Hazard Analysis and a Short Circuit Coordination Study be carried out when there is a change 30 % of load in the firm.
• Dielectric breakdown
• Faulty operational practices like operating the switches, covers of the devices owing to untrained professionals.

Arc Flash Analysis procedure involves some of the steps indivated here after:
1.Calculation of arcing current with the inputs of fault currents, bolted fault
currents, gap in conductors.
2. Calculate Incident Energy. Incident energy is the amount of energy received per unit area on a surface. The distance from the worker is the working distance.
3. Determine Flash Protection Boundary as determined through NFPA 70 E.
4. Determine Protection Boundaries with PPE and without PPE depending on the operating conditions.
5. Calculation of Hazard Risk.
6. Short Circuit current Calculations.
Arc Flash Calculation and Arc Flash Hazard Analysis at VBE implements the following
• Develop a one line diagram.
This helps in identifying the location of each equipment, the period of operation of the said
equipment and possibility of repair or upgradation or replacement or removal of the equipment so as
to rendezvous the ongoing operating conditions of the firm.
• Data Acquisition This enables to develop the mathematical model complying with IEEE 1584 2018. The range of operating voltages, transformers, transformer connections viz., wye-wye, delta-delta, loading conditions of the firm, conductor configurations like VCB,VCBB, HOA,VOA etc. Range of operating voltages, size of the equipment, the operating voltages and MVA ratings.
• Identify alternate measures in case of interruption so as to prevent a downtime in production.
• Tabulate previous Arc Flash Study Reports, change in loads.
• Short Circuit Coordination Study , Fault current Calculation, Calculation of incident energy, circuit breaker ratings, tripping values, clearing time calculations and formulation of mathematical models proposed by IEEE 1584 2018.
• Arc Flash Hazard Analysis
• Identify high risk equipment, operating conditions depending on the peak load.
• Recommend the required labelling , Arc Flash PPE complying to NFPA 70E, NFPA 70B, OSHA 29 CFR 1910.
• Provide required training to the operating personnel in handling the Hazardous equipment, know the Safety measures in an incident of an Arc Flash , knowledge over Arc Flash Hazard labels, Selection of required PPE , operating distances for various conditions.
• Prepare a Report with the necessary guidelines in a pliable Arc Flash Study Cost.

The vast clientele at VBE qualifies us to keep up with the safety practices inn a global approach.
Arc Flash Study companies aid in mitigating these adverse effects prevention and significant mitigation of such hazardous occurrences. Businesses are rendering options to provide the requisite safety measures to the operating personnel. Arc Flash also is associated with financial concerns to the company due to the shut down of the facility, stalling of production, Medical expenses to be met, Insurance , damage to the equipment, fines levied by the government, Legal expenses to be met up as much as $30M or more. These adverse effects multiply when an Arc Flash occurs in a highly flammable environment as in the case of Gas plants, Chemical industries, Petroleum and Oil firms and other explosive causing industries. These statistics incline the industries and businesses to emphasize on the proper addressing of the Electrical Hazards that occur in a firm. The problems associated with it viz., Short circuits, Failure of Insulation, Circuit Breaker failures, Lightening Arrestors malfunction, Failure of Protective Devices, Harmonics, Arc Flash. Arc Flash is thus found to be one of the grave concerns of any business.
