Mitigate the dangers of arc flash incidents and prioritize electrical safety with our Arc Flash Risk Assessment solutions. At Wire Consultancy, we have a deep understanding of the complexities involved in electrical systems and the potential risks they pose. Our skilled team conducts detailed assessments to evaluate your equipment, analyze fault currents, and determine incident energy levels.
We Strive to Drive
An Arc flash risk assessment is a type of electrical explosion or discharge that results from a low-impedance connection through the air to the ground or another voltage phase in an electrical system.
Arc flash temperatures can reach or exceed 35,000 °F (19,400 °C) at the arc terminals. The massive energy released in the fault rapidly vaporizes the metal conductors involved, blasting molten metal and expanding plasma outward with extraordinary force. A typical arc flash incident can be inconsequential but could conceivably easily produce a more severe explosion.
The result of the violent event can cause destruction of equipment involved, fire, and injury not only to an electrical worker but also to bystanders. During the arc flash risk assessment, electrical energy vaporizes the metal, which changes from solid state to gas vapor, expanding it with explosive force.
We at Wire, use the tested and proven software ETAP and DIGSILENT to perform short circuit studies and arc flash risk assessments. These assessments meet the new regulations noted on NFPA 70E, IEEE 1584, NESC (National Electric Safety Codes), and OSHA.
The objective is to perform power flow analysis and voltage drop calculations with accuracy and reliability. In this step, we calculate bus voltages, branch power factors, currents, and power losses. Load Flow Analysis allows the user to compare numerous study cases at a glance in detail to perform AC, DC, single-phase, and three-phase load flow studies on your network concurrently.
An electrical power system consists of various equipment such as a generator, transformer, motor, switchgear, capacitors, harmonic filters, cables, etc. The complexity of a power system and its components/ equipment can cause failure, no matter how carefully the system/ equipment is designed. These system/ equipment failures manifest themselves as insulation breakdowns, which can result in faults/ short circuits.
The Arc Flash Risk Assessment is used to determine worst-case arc flash energy levels. Arc Flash Risk Assessment identifies and analyzes high-risk arc flash areas in your electrical power system.
