Arc fault circuit interrupter, systems, apparatus and methods of detecting and interrupting electrical faults
Abstract:
In all electrical circuits, various arcing conditions can arise, however, the primary ones are series arcing (low current arcing), and, parallel arcing (high current arcing). An arc fault circuit interrupter (“AFCI”) that protects for both series and parallel arcing is called a combination type. An AFCI is a device that controls the effects of electrical arcing by opening a circuit through a tripping mechanism that isolates the load from the supply line upon detection of an arcing condition. In this invention, this arc fault is detected by a circuit employing a Hall-Effect sensor (“HES”) integrated circuit, and a microprocessor among other components.
