ARC Flash Study Analysis

Arc Flash labels are clear and easy to understand specifying the need of PPE, operating distance, incident energy, arc fault current available, HRC, Appropriate PPE in accordance to the local and international standards. The Arc flash labels are computer modelled and provide you with right labelling for the required operation. Arc Flash study cost with VB Engineering proves to be very effective with the RIGHT suggestions suiting your business needs and to meet your quest in providing safer work place conditions for the working personnel. The Arc Flash Study cost is justified with the advantages Arc Flash Hazard analysis has to offer. The periodical Arc Flash Study at the facility and the records of the Arc Flash Study reports turns away the event of being fined by the local laws and international standards, hospital expenses to be met are averted, loss in production due to an outage caused by an Arc Flash, need of new equipment that are expensive and have been damaged during Arc Fault can be totally avoided and thus saving millions of Dollars. And as such the Arc Flash Study Cost is an investment benefitting the business.

Most recent Arc Flash incidents observed in Western Australia, Perth and other locations indicate that an Arc Flash Incident can occur at any facility like commercial, residential, industrial points. Some of the causes that are observed to be causing Arc Flash Hazard are listed below:

Human error: This is the case of an error in majority Arc Flash hazards like in the cases of the operating personnel dropping tools, being non vigilant while opening or closing contacts, negligence in following the Arc Flash Hazard analysis guidelines, ignorance of the high risk working environment, non-compliance of the standards provided by safety organizations.

Low maintenance: Periodic check on the equipment helps in identifying any damage, making sure that the circuit breakers, fuses are in working conditions and are not prone to wear and tear. Damage in circuit breakers, other protective devices. Moisture

Dust and debris accumulation
Rodent infestation, cob webs and other small animals making it a conductive path for the Arc current. Poor design. Inadequate Ratings of fuses and other circuit breakers, digital meters connected in the circuit, employing poor quality equipment.

Erroneous connections and installations

Arc Flash study helps to identify these causes of Arc Flash, Analyse which type of equipment is at risk of an Arc Flash, methods to mitigate the arc, suggest required PPE for the Arc Flash calculation performed at the facility. Arc Flash Study cost with VB Engineering is in accordance with the company's expectations and the size of the facility. Arc Flash Analysis with VB Engineering includes a detailed load flow study, short circuit coordination study, harmonics, contingency analysis meeting the arc flash study requirements.

Arc Flash Hazard Solutions and Report

Data Acquisition: All the data of the system up-to-date from the company records and a field survey by our team of experts is collected and analysed, formulate the causes that may result in an Arc Flash.

Modelling the data : At VB Engineering we employ standard tools like ETAP(Electrical Transient Analysis Program), SKM, Easy Power, TANTRA that are helpful in analysing thousands of buses at a go. Single Line Diagrams showing all the connections, ratings, transformer, tap changers, fuses, circuit breakers, MCC (Motor Control Centre) s, X/R ratios, power angle, Transformer sizes, types of phases, grounding types are depicted and modelled to determine possibilities of arc flash , methods to reduce the effects of Arc Flash Hazard.

Arc Flash Hazard Analysis: Our skilled Engineers propose operating practices that act in alternative practices to create awareness in the working personnel about the Arc Flash through our systematic and elaborate Arc Flash Hazard Analysis. At VB Engineering in accordance with the IEEE 1584-2018, and Australian standards for the Arc Flash calculation are employed. Arc Flash Calculation is MAINLY the determination of the Arc Fault current, Bolted Fault Current (3- phase symmetrical fault current), IE (Incident energy) Amount of Incident energy the working personnel is exposed and methods of reducing the amount of incident energy with short circuit coordination study.

Short circuit coordination study: Based on the mathematical models developed, the normalized incident energy for the different modes of operation of the electrical system and the different configurations of the conductors, air gaps between the conductors, cable sizes, types of phases in the system HRC categorized. The time taken for the interruption of short circuit. The TCC (Time Current Curves) provide the necessary data for the short circuit coordination study and the protective device coordination. The main avidity of the flash hazard analysis is to prevent the Arc Flash occurrence at a very early stage. This is made possible with devices called as Arc Fault Circuit Interrupters. Unlike circuit breakers that are most widely employed for protection, Arc Fault Circuit Interrupters identify the electric arc current that may flow in unintended path and opening the circuit before it continues to be further energised causing an Arc Flash and fire. With short circuit coordination study reports our team of experts suggest modifying or employing new settings for a coordinated operation of protective devices based on the overlapping of the TCC of the protective devices and switch gear assemblies.

Arc Flash Study Report: Based on the Arc Flash Survey at the facility, VB Engineering formulates a detailed Arc Flash Study Report. The objective of the Arc Flash Survey is to perform flash hazard analysis meeting with the arc flash requirements and to provide a safe working environment for the employees. Arc Flash Study Report further provides with arc flash labelling in compliance with OSHA, NFPA 70 E, NEC, AEC, ENA standards. We provide the necessary Arc Flash Hazard training to the employees in identifying the Arc Flash Hazard environment, read and understand Arc Flash Hazard labels and there by choose right working practices and appropriate PPE and Arc Flash Approach boundaries. With regards to Electrical safety at your workplace Arc Flash study helps you to avert the adverse effects caused during an Arc Flash. Consult our Arc Flash Study consultant for a cost effective and expert advice.

Arc Flash is seen from the statistics to be more prone to causing fatal injuries, injuries with severe burns, damage to eyesight, ears and hearing ability, breathing problems. Safe work practices are always the best protection. When a fault current flows in a low resistance path it leads to an arc flash. The fault current when attains a sufficient energy, results in ionizing the air surrounding the conductors leading to a blast called as Arc blast or Arc Flash.
