摘要： The present invention is directed to locating electrical faults (61) in an electrical circuit (50), in particular electrical faults (61) in transmission wires (60) of an electrical circuit (50). Examples of the present invention provide a method and apparatus for opening a switch (90) in the electrical circuit (50 9 to cause an open circuit or discontinuity at the fault (61); transmitting (100) a signal to be reflected from the open circuit or discontinuity and receiving (100) the signal reflected from the open circuit or discontinuity to determine the location of the fault. Examples of our invention are particularly suitable for high voltage systems, for example over 100V.

摘要： An electrical power distribution system can distribute electricity from a source to a load, and can comprise at least one solid state power controller (SSPC) having an input coupled to the source and an output coupled to the load. The SSPC can include an open shunt switch connecting the input to ground. A control circuit can couple to the shunt switch and can be configured to detect a failure in the SSPC. A fuse can be connected between the source and the input. A failure can be detected in the SSPC and the control circuit can close the shunt switch to cause a short circuit that will blow the fuse and isolate the SSPC from the source.

摘要： A method for detecting electrical faults in an electrical circuit having transmission wires for power transmission includes determining whether a potential electrical fault condition exists along the transmission wires and confirming the potential electrical fault is an actual electrical fault. If the potential electrical fault is confirmed as an actual electrical fault, the method may disable the electrical circuit.

摘要： Multi-semiconductor SSPCs (300) that solve bus level problems affecting systems as well as controller level problems affecting individual multi-semiconductor SSPCs (300) are disclosed. Bus level and controller level problems adversely affect multi-semiconductor SSPCs (300) and their associated systems. The disclosed multi-semiconductor SSPCs (300) solve both bus level and controller level problems by implementing controlled rate-change of voltage (dv/dt) ramp-on rate, to ensure that the voltage on the input bus does not collapse when a multi-semiconductor SSPC is commanded closed and that a minimum amount of power is being dissipated evenly across the switching semiconductors (390).
