Nowadays, hazard that associated with arc flash incident is increasing every year by year. The increasing of the incident has been brought to our attention. This study proposed so that it can help the industries to eliminate or at least reduce those hazards. Through the analysis of this project, the limitation for the arc flash occurs will be proved through the stimulation of the short circuit calculation and the boundary calculation by using the ETAP software. There are few steps that will be included, which is data collection process, develop single line diagram, arcing short circuit calculations and also flash protection boundary calculations. The workers in industries should take the harm of arc flash as a serious matter and be aware of arc flash. The expected result from this project will be the limitation that will be gain in the end of this project. The limitations of the protective boundary to control the arc flash in industries. The limitations of the protective boundary from the result are also to control the usage of Personal Protective Equipment (PPE). For each distance form a system or work place there will be a certain suitable level of PPE. The result will help to reduce harm and accident that happens in industries. The analysis of this project basically will be based on industrial field, where the data that used to do the analysis will be involving the industry site.

This book is essential reading for anyone responsible for designing or putting workers to task on, or near, large power electrical systems. This is especially relevant where local health and safety law uses a risk-based approach to electrical safety such as in Europe. It is based upon a bedrock of risk management methodology using the 4Ps of Predict, Prevent, Process and Protect to ensure that arc flash hazards are systematically identified, analysed, and prevented from causing harm. Each of the 4Ps are described in detail starting with a quantitative prediction of harm from the arc flash hazard and then a separate chapter on prevention based upon practical measures avoid or minimise harm set against a hierarchy of risk control measures. The chapter on process, policy and procedures gives advice on a methodical approach to creating rules and ensuring competence. Finally, the chapter on protection describes, as a last resort, how personal protective equipment can be selected, used, and maintained. This book is packed with the fruits of the author’s vast experience and there is a chapter dedicated to myths and mysteries as well as separate chapters for electrical utilities, duty holders, service providers, contractors, legislation, and data collection.

Electrical workers are exposed to arc flash hazards that require equipment be de-energized during maintenance periods. This contributes to a significant loss of system functionality resulting in costly outages. Industry standards and health and safety regulations require the implementation of arc flash analyses on electrical equipment; however, the standards are often equivocal in terminology and difficult to determine when to appropriately apply. Arc flash analyses require the use of various parameters combined in complex calculations. These exhaustive procedures make it nearly impossible to perform an accurate arc flash assessment in the field. Qualified field personnel need to understand the contributing factors of an arc flash and available retrofit methods for reducing the associated incident energy. This thesis investigates the underlying concepts of an arc flash and presents a concise method for performing the analysis on a desired system using the Cooper Bussmann Short-Circuit Point-to-Point method, as well as the IEEE 1584 standard. An electrical system representative of a small industrial plant is modeled and simulated using Operation Technology Incorporated's ETAP® (Electrical Transient Analysis Program) software. To aid in the reduction of an arc flash's total incident energy, several sensitive arc flash parameters are defined, and with the use of Matlab, modeled and examined with the intention of allowing field personnel to quickly and safely recognize methods for arc flash mitigation. This thesis can inform field personnel, entry level engineers and engineering students, of the concepts and sensitive parameters associated with arc flash analyses.
