Abstract
Electrical fuse indicators, systems and methods for detecting when fuses enter an open state involve a wireless identification element, which alerts a communication unit that the fuse has entered an open state. The wireless identification device may include an antenna. The antenna may be in contact with a fuse element, such that opening of the fuse element renders the antenna inoperable. Alternatively the antenna may be connected to the fuse element in such a manner that opening of the fuse element alters the frequency on which the antenna transmits. A logic port may also be used to detect the operational state of a fuse. Use of such indicators is compatible with existing infrastructure.
