The arc-flash protection is critical for the safety of personnel and the integrity of the facilities. The arc-flash study assists facilities to conform to the workplace electrical safety standard. The best approach to electrical safety is to work only on de-energized equipment that has been appropriately locked out and placed in a safe condition. However, this is not always possible due to the equipment design and operating constraints. For this reason, Canadian and American safety standards established requirements for achieving arc-flash analysis and the use of personal protective equipment (PPE) for personnel working near energized lines or equipment.
Our experts will assist you to identify the fault currents that are the source of arcing – they may be ac or dc. They have extensive knowledge of electrical networks and power systems, adjustment and coordination of protective devices, the evolution of electric arcs and mitigation resources. The arc-flash study includes the following elements – applied to electrical rooms and substations: the arc-flash boundary, the incident energy (cal / cm2), the hazard / risk categories, personal protection equipment (PPE), modifications in the protection, hazard reduction methods, etc. ETAP, SKM, CYME (CYMDIST) and EasyPower are the software used for the analysis. The standards used are CSA Z462, NFPA 70E or your most restrictive standards.
