The continuous supply of electrical energy is an inherent requirement of today‘s society. The power outages in North America and Europe have shown how dependent we are on this. Everything came to a standstill. Arc faults represent some of the risks to a reliable supply of electrical energy. Even today, they still occur in electrical power distribution systems, despite all the precautionary measures that are given due consideration and implemented in advance. They are caused by human error when work is carried out on the switchboard, as well as by contamination or condensation, overvoltages...

Herbert Schmolke, VdS Loss Prevention, Cologne The arc fault protection system offered by Eaton is based on the principle of "prevention instead of limitation" Due to the proven effectiveness of ARCON, the GDV Gesamtverband der Deutschen Versicherungswirtschaft (German Insurance Association) and the VdS Schaden-verhutung (VdS Loss Prevention), in their guidelines for fire insurances - known as VdS 2344:2012-07 "Procedures for testing, approving and certifying products and systems for fire prevention and safety technology" - have defined an effectively functioning arc fault protection...

Preventing Damage, Ensuring Service Continuity. • Arc fault was initiated by means of a glow wire according to IEC/TR 61641. • Arcon quenched after 2 ms. • Only combustion traces. • Immediate restoration of service. The effects of an arc fault are very similar to those of an explosion. This ranges from the risk of death and injury to persons, extensive damage to switchboard systems, to several weeks of downtime or even the exchange of the damaged switchboard system. In the worst case, the production downtime can even lead to bankruptcy as customers have found other suppliers during this...

Personnel protection Failure to observe the five safety rules When a shielded control current cable was being drawn in, the shield that was earthed at one end touched the live main busbar and initiated an arc fault that caused considerable damage to the system. Contamination and condensation In an animal feed plant, an arc fault occurred in a switchboard that had been in operation for several years. The cause was considerable contamination and condensation that reduced the insulation gap. Errors when working on live switchboard installations can be fatal. All reputable manufacturers of...

Chemical industry Continuous manufacturing processes require the provision of an uninterruptible power supply. Whether this is in the refinery, in granulate production or other manufacturing processes that chose MCC technology years beforehand in order to optimise the electrical power supply. What is better than preventing the risk of damage from arc faults directly? IT centres Whether this be for payroll accounting, cash debits at the cash dispenser or other services in this sector. The supply of electric power must be ensured in all circumstances – even in the event of an arc fault. Glass...

Nuclear power stations Faults occur in nuclear power stations from time to time. Since the Chernobyl disaster public sensitivity to this has been particularly heightened. The operators are required to deal with operational safety with the highest priority, particularly in the context of the planned lifetime extension. A suitable arc fault protection system is therefore indispensable. Shipping applications A considerable proportion of containers on container ships are refrigerated. The power supply required for this must be available during the entire passage without any interruption. Modern...

Controlling Arc Faults Safely. 1. Detection The arc fault is reliably detected by means of two separate detection variables. The arc fault produces an overcurrent which is detected by means of measuring transducers. The second detection variable is the extremely intense light emitted from an arc fault. This light is detected with fibre optic sensors. Some of this intense light emission enters the core of the fibre optic cable radially. This signal can then be evaluated at the end of the fibre optic cable. Any incorrect releases due to flashes or welding arcs are prevented by evaluating both...
