3 Arc flash The threat is real Complying to European safety standards does not automatically prevent arc flash incidents. Despite intrinsically safe equipment designs and the preference of working on deenergized equipment, arc flash accidents do actually happen all across Europe. Arc flash is the result of an electric current that is passed through air when insulation or isolation between energized conductors is no longer sufficient to withstand the applied voltage. The majority of arc flash events take place during or immediately after work on an electrical installation. An arc flash is often the result of human actions, such as a circuit breaker racking failure, misplacement of a test probe, or dropping a tool on live parts of the installation. Some work activities such as voltage testing, fault finding, and commissioning take place with energized conductors in close proximity. Arc flash is often an unexpected event, due to the fact that human error is difficult to predict. The result is commonly destruction of equipment involved, fire, and injury to the workers. A common misconception is the delusion that high voltage systems are more dangerous than low voltage systems with regard to arc flash hazard. Low voltage installations can have very high potential arc energy levels while they are operated and worked on much more frequently. An electric arc fault may be rare, but the damage caused and its effects are extremely serious. 3

4 Why is Arc a hazard? The electrical arc flash is associated with release of large amount of heat energy that causes copper and steel of the electrical equipment to melt and evaporate almost instantly. The result is a fiery explosion that has the capacity to produce extremely serious and fatal injuries. Professional analysis is required in order to quantify such potential and properly protect staff from this risk. 4

5 Arc Flash Safety Solutions Common practice Throughout the world, arc flash threatens personnel safety, companies face lost time, lawsuits, fines, equipment damage, facility downtime, and lost production. Arc flash hazards impact all business areas, namely: Safety Legal Financial But there is a solution. Regulations European codes and standards do not specifically require a risk assessment for arc flash hazard, despite the fact that arc flash is a recognized risk. Many electrical workers will be able to tell you about real accidents or near misses that they have seen or heard about. According to the EN Standard, which is applicable to operation of electrical installations, work is divided into three categories: live working, dead working and working in the vicinity of live parts. Because most work is carried out under the dead working condition it is often assumed that arc flash hazard is not a concern. Some work activities such as voltage testing, fault finding, and commissioning take place with energized conductors in close proximity, either because there are allowed exceptions or because the activity requires it. Even the act of making the equipment safe to work on can expose the worker to this hazard. Eaton has the capability of performing an Arc Flash Hazard Assessment of your electrical installation. Based on this assessment, we can provide specific recommendations to make working on the electrical equipment safer. Safety Means Knowing Your Potential Hazards. Ensuring that your facility has the best possible arc flash safety plan in place is vital to the safety of your employees and the continued success of your business. While adoption of international arc flash safety standards is increasing, they may not provide the specific attention to detail required for safe work environment with respect to arc flash, even under worst case conditions. Eaton has the experience and expertise to help you understand the level of arc flash hazard in your facility and optimize your safety program accordingly. Energy transfer mechanisms of an arc flash. Distances are important. The Eaton Approach Eaton s Arc Flash Analysis helps to deal with Arc Flash hazard. The starting point is to prevent dangerous situations. Through a comprehensive analysis of every part of your electrical network, we provide insight into the arc flash hazard at any location. We quantify the risk. In addition we look into any concerns relating to short circuit capacity and selectivity. For any locations that have dangerously high arc flash incident energy we investigate solutions to significantly lowering the probability of an arc flash incident and ways to limit the workers exposure by system design, equipment modifications, alternate protection settings and work methods. Optimized settings of protection devices, use of override switches, equipment modifications, remote switching are only a few of many methods used to effectively improve electrical safety. The costs of the solutions vary, but even higher cost solutions are small investments compared to the costs of dealing with the consequences of arc flash accidents. A top-notch safety plan incorporates not only arc flash hazard analysis recommendations, but also practical training for personnel who operate and maintain electrical equipment. Eaton offers both. Eaton s trainers are the electrical engineers who perform arc flash hazard analyses and often also work in the field install. When you train with us, you re assured of getting the most current information, techniques, and procedures available to keep your personnel safe and your processes running. Implementation starts with awareness. 5

6 Arc flash hazard analysis is critical to working safely on or near energized electrical equipment A comprehensive arc flash hazard analysis An arc flash hazard analysis is critical to the safety of plant personnel working on or near energized electrical equipment. Based on extensive empirical testing and research, the analysis allows accurate assessment of the arc flash hazard by quantification of the release of thermal energy from the arc. At the conclusion of the assessment Eaton will provide recommendations to both prevent and to mitigate the hazard. Eaton s highly-qualified power systems engineers performed many arc flash assessments in all types of industrial plants in Europe. Every engineer has access to a variety of analysis tools to best address the safety risks of your unique system. With the use of proprietary software and models based on IEC and IEEE standards, complex models are executed including fault current calculations and protective device coordination. For each system node, multiple scenarios are run to evaluate protective device duties, devices clearing time, arcing fault currents, duration of arc and resulting incident energy. Eaton s engineers draw on past experience, rigorous training and expertise in providing recommendations which are compiled in a written report. Engineers are available to present the findings at the customer site at which time the basic personnel training can also be conducted. A comprehensive arc flash hazard analysis includes the following services: Creation or verification of one-line electrical drawings Arc flash system studies include: - Short circuit and Protection coordination studies - Arc Flash calculations and Consulting The Study Report includes: - Input Data - Short Circuit Analysis Results - Time-Current Coordination Curves (TCC) - Worst Case Incident Energy - Arc Flash boundaries - Safe working distances - Practical methods for reducing arc flash hazards - Personal protection equipment (PPE)- Safe work practices Arc Flash labeling and training Eaton s extensive experience in arc flash hazard analysis will provide the best solutions to protect what you value most. 6

7 Standards for Arc Flash The Arc Flash calculations as performed by Eaton, are based on the following standards: IEEE NFPA 70E, 2012 Arc Flash hazard analysis complies with the following European standards: EN IEC IEC TR (Low Voltage) IEC (Medium Voltage) IEC Total Arc Flash Solutions from The Industry Experts Eaton s engineering solutions stress prevention, protection and preparation.
