Abstract
In 2007, 9,128 fires are attributed to electrical equipments. These fires resulted in 29 deaths and 262 injuries. Arc-faults were one of the major causes of these fires. When an unintended arc-fault occurs, it generates intense heat that can easily ignite surrounding combustibles. Conventional circuit breakers only respond to overloads, short circuits, and leakage currents. Therefore, the breakers do not protect against arcing conditions. This paper presents results obtained in experiments on ignition behavior of wire by series arc fault currents and techniques developed to detect the arc-faults. The developed technique was tested after installation to make sure they are working properly and protecting the circuit. If the developed arc detecting technique is applied, the electrical fires caused by an arc-fault can be reduced.
