Abstract:
1. A computerized electricity system for connecting loads to at least one power source, the computerized electricity system comprising: (a) an arc fault detecting sub-system for detecting arc faults, said sub-system having at least one module, each said module including: (b) a processing unit electrically connected to each said module of said arc fault detecting sub-system, so as to receive data corresponding to said analog signal, and said data from said digital circuit, said processing unit for identifying of said arc faults, and wherein said processing unit is configured to command said relay unit to disconnect said current in response to said identifying of said arc faults, and wherein said processing unit is configured to provide said command only if several pre-determined conditions are met, said conditions including: (I) after a detection of said potential arc fault event by said arc fault detecting sub-system, said current measurement remains substantially unchanged, and (II) after a detection of at least one additional potential arc fault event by said arc fault detecting sub-system, said arc fault events are found to occur in an acyclic fashion.
