What is Protection Coordination Study? The electrical protection coordination study is a study or analysis to determine the setting of protection relay and circuit breaker. Its main purpose is to obtain an optimal compromise between protection and selectivity. The study includes determining fault clearing time and coordination of upstream electrical protective equipment. Proper coordination and disruption clearing times can help reduce damage to electrical equipment and protect workers from harm. Study and analysis of coordination of protection equipment is one

What is Power Quality Study? Electric power quality study is a systematic analysis to identify power qualities issues, look for the root causes and recommendations for improvement in an electrical system. Those issues are such as surges, harmonics, high frequency noise, transient voltages, wave distortion, interruptions, frequency variations, etc. Power quality studies are also meant a focused and systematic approach to solve complex problems in a power system. Power qualities analysis is for new builds and for existing plants. All

What is Short Circuit Study? Definition of short circuit study is an examination or analysis or evaluation of an electrical system to determine the magnitude of currents that can flow during an electrical fault and compare those values to the ratings of installed equipment. It is activities related to short-circuit analysis, including design considerations for new systems, analytical studies for existing systems, as well as operational and model validation considerations for industrial and commercial power systems are addressed. A Short-circuit

What is Load Flow Study? The definition of a load flow study, or power flow studies, is a numerical analysis of the flow of electric power in any electrical system. A load flow study is also an assessment of the steady-state conditions of the electrical system. Its goal is to determine the flow of power, current, voltage, real power and reactive power in a system under any load conditions. During the design phase of a new project or when evaluating

What is Power System Study & Analysis? – General Overview The power system study is made up of several electrical engineering analysis and investigations. Electric power system study is also a group of studies used to analyze a power systems response to events over different time periods. An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. The ultimate goals of power system studies are to have a safe, efficient and reliable

What is Arc Flash Study? An arc flash study or risk assessment is engineering studies that identifies and analysis the specific arc flash hazard for an electrical equipment within a facility. The study or assessment of the arc flash hazard risk is an engineering study. This is with certain procedures to determine the amount of incident energy at an electrical facility or device. From the amount of incident energy, the arc flash hazard level will be determined, personal protective equipment

Introduction to Arc Flash Boundary In this article we will briefly discuss the distance limit and the safe and unsafe area of an electrical equipment and equipment from the risk of electric arc flash. The distance limit or area is often referred to as arc flash boundary. There are several terms related to arc flash boundaries called approach boundary. Approach boundaries will also be discussed briefly in this article. In each boundary and area requirements will be discussed in the

Arc Flash Hazard Calculations In the previous article we have discussed the definition, hazards, level of risk (read: Arc Flash: Definition, Hazards and Risks) and the causes of arc flash (read: Arc Flash Causes Analysis). This article will discuss in more detail the standards and methods of calculation or how to calculate the value of the arc flash hazards or incident energy and boundary with a mathematical calculating formula developed by IEEE 1584. ——————————————— IEEE 1584 – Guide for Performing

Arc Flash Causes In the previous article entitled Arc Flash: Definition, Hazards and Risks have been briefly reviewed understanding, danger and the level of risk associated with arc flash. This article will discuss more in depth the analysis of some common root causes of the arc flash phenomenon. In brief, the causes of arc flash and common electrical work accidents are: Carelessness Isolation failure Bad or loose connections Poor maintenance of circuit breakers Failure when disconnecting short-circuit (short-circuit) Water or

What is Arc Flash Definition? Arc flash definition according to NFPA 70E is the sudden release of unexpected heat and light energy produced by electricity passing through the air like a lightning. Arc flash is also a phenomenon that is usually caused by accidental connection between live conductors, or between live conductors and the ground. Temperature at the arc point can reach or even more than 35000 Fahrenheit. It is four times the surface temperature of the sun. The air
