Thorough Arc Flash Risk Assessment Available Nationwide

An arc flash study or risk assessment is an engineering study that identifies and analyzes the specific arc flash hazard for 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 that must be used when working on this device.

The electrical protection coordination study is a study or analysis to determine the settings of protection relays and circuit breakers. 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 part of the electric power systems study. Protection coordination analysis studies are carried out after a load flow study and short circuit study is carried out.

The 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 and short circuit protection devices. 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 protection fault study holds crucial importance in power systems. Without performing a short circuit study, we cannot go for protection coordination and the arc flash study and it is a recommended practice for any power system facilities.

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 changes and additions to existing electrical system, a load flow study is necessary to ensure system voltages and current remain within safe limits and whether additional equipment or services will be required. The flow of electric power in any electrical system is referred to as “Load Flow”.

The definition of electric motor starting study and analysis is an activity to determine and analyze the behavior of a motor during its starting stage. This study is usually applied to large motors. Motor starting analysis includes evaluation of the starting current, voltage drop, voltage dip, and required start time. Motor starting studies are carried out in large commercial and industrial systems where a large capacity motor can have undesirable consequences on the performance of the motor, system and surrounding equipment.

We collect any available One-Line diagrams and panel schedules that are available. This is used as a starting point for the data collection. This is typically done prior to the site visit. While on-site, specific information is collected regarding conductor sizes and lengths, distribution equipment ratings and types, overcurrent protection device models and settings, transformer ratings and impedances, as well as incoming energy levels to the plant from the Utility.

We provide full service drafting for electrical diagrams in AutoCad format.

We maintain active licensing with SKM, ETAP, and EasyPower. If your facility is in need of an arc flash study update, we can fill your needs regardless of the software used previously. We would only need access to the electronic project files used most recently. This will save us time and save you money.
