Short Circuit and Coordination Studies & Arc Flash Analysis
Electrical Engineering Services
RWB Consulting Engineers provides quality electrical engineering services to commercial, educational institutional, and industrial buildings. One of our many areas of MEP expertise includes electrical engineering studies. Specifically, RWB offers short circuit and coordination studies & arc flash studies to our customers in the Dallas Fort Worth area.
As electrical engineering consultants, we understand the importance of an electrical system that operates correctly and safely. Especially on mission-critical projects like telecom facilities, data centers, and corporate campuses, the constant flow of electricity is critical. That’s where our 30+ years of experience comes into play. We’ve been on both sides of the equation; designing projects and evaluating others. As a result, we’re able to provide short circuit and coordination studies and arc flash analyses that meet our client’s needs.
The purpose of a short circuit and protective device coordination study is two-fold. A short circuit study ensures that the electrical equipment design for the facility is braced to handle the amount of potential short circuit energy in the system. A coordination study ensures that the facilities overcurrent protection devices are properly set to ensure proper sequence of tripping in the event of an electrical overcurrent or fault.
Without this study, buildings can experience unnecessary interruptions in power service due to miscoordination and nuisance tripping. Also, this study models the worst-case-scenario condition for electrical power. That can minimize damage to any electrical system components.
This study addresses questions such as:
The RWB team utilizes a combination of the provided electrical drawings and information from the electrical contractor to model the electrical system. With a short circuit and coordination study, owners can rest assured that their electrical building systems are correctly set up for smooth operation.
An arc flash analysis is primarily a safety study that is required by OSHA and NFPA 70-E.
The reason an arc flash analysis is so important is because an arc fault can cause a dangerous explosion of electrical energy. An arc flash analysis improves technician safety when working on live electrical equipment.
Arc flash studies are performed to determine:
As a result of the study, each piece of electrical equipment on a project is given an Arc Flash Hazard Rating. Labels are applied to the equipment with this information so that anyone working on the equipment is aware of the rating.
Every commercial project should have a short circuit and coordination study, as well as an arc flash hazard analysis completed. These electrical studies not only support a smooth startup but also ensure the safety of those working on the equipment. When possible, these two studies should be completed simultaneously to maximize the benefit to the building owner. Contact us to learn more about our electrical study services.
