NFPA 70E Section 130.4 mandates that a shock risk assessment be conducted prior to starting any energized work, while Section 130.5 requires an arc flash risk study to determine if an arc flash hazard exists. If a hazard is identified, the assessment must also establish the appropriate safety-related work practices, define the arc flash boundary, and specify the correct personal protective equipment (PPE) to be worn.
Arc flash analysis involves several steps: Data Collection, Power System Modeling, Short Circuit Study, Protective Device Coordination, Arc Flash Calculations, Reporting, and Label Installation.
NERC, or the North American Electric Reliability Corporation, requires every entity to register with its regional entity. As grids become more complex and new technologies emerge, NERC is actively enforcing existing and new requirements, adjusting compliance reporting frequency. By federal law, NERC monitors compliance status and can impose sanctions or fines for non-compliance.
A short circuit study determines the magnitude of current flowing through the power system at critical points during various time intervals after a fault occurs.
NERC Compliance standards MOD-025-2, MOD-026-1, and MOD-027-1 ensure an accurate representation of the steady-state and dynamic response of generating units for power system simulations. This process can be complex, and ArcFlash Guru is here to assist you throughout.
An arc flash occurs when electric current travels through the air instead of its intended path, resulting in extremely high heat that can cause severe burns, blinding light, and explosions that may lead to hearing damage or fatal injuries.
ArcFlash Guru offers exceptional testing and commissioning services to ensure the long-term, efficient operation of electrical power equipment. Regardless of your power system's size or age, proper maintenance is crucial for maximizing reliability. A comprehensive maintenance program includes inspection, maintenance, testing, and periodic equipment rating evaluation.
Relay testing services include: Electromechanical & Solid State, Microprocessor, End-to-End Testing, Fault Simulations, Protection System Evaluation, IEC 61850 Compliant Testing, and NERC Compliance Testing. Proper maintenance involves more than just testing; it requires a thorough inspection and maintenance program.
Power systems engineering software is a valuable tool for studying power systems but should not replace knowledge and experience. ArcFlash Guru utilizes various commercially available software packages, supported by some of the most experienced professionals in the industry across multiple applications. We welcome the opportunity to demonstrate our analysis capabilities on your next project.
