Modern society heavily depends on an uninterrupted supply of electric power. Prolonged power outages cause loss of business to the power supplier and loss of production to the power consumer. Regardless how safe a power system is, faults do occur. This being the case the damage caused by power system faults must be kept to a minimum level. The ultimate solution is to selectively isolate the fault as fast as possible, while maintaining the operation of the healthy network parts. A VAMP arc protection system can principally be implemented in three different ways, as a autonomous master unit system, as a part of the Schneider Electric protection relay system or as an integration between a master unit system and the Schneider Electric protection relay system.
