Abstract: Aircraft ground power cable management and monitoring systems and methods including arc fault protection. Disclosed systems are especially well-suited for high power systems such as 400 Hz aircraft ground power supply systems and cable assemblies.

Abstract: The present disclosure describes various alternative embodiments of plug force testers, in particular devices well-suited for testing aircraft ground power connection plugs. The disclosed plug force testers provide a fixed, well-supported position for test pins on which a plug is inserted, which can be positioned to correspond to a height or orientation of the pins in an actual aircraft. Embodiments described also may include means for preventing excessive force application during testing.

Abstract: A portable power distribution unit for safely distributing high wattage power supplied from mobile generators to lower power test adapter units and systems. Embodiments disclosed include a structurally rigid housing shaped to facilitate secure holding by an operator's foot, a 400 Hz power connector adapted for connection to a mobile power generator, a circuit breaker matched to the rating of the system to be powered and connections for conversion of the six-pin output from the mobile generator to a three or four-pin input for the system to be powered.

Abstract: A modular, repairable aircraft ground power receptacle includes a base containing pin bases with outwardly opening sockets. Removable pins are secured in the sockets and a pin cover plate is placed there over with prong ends of pins extending through the pin cover plate for connection with a ground power plug. Damage pins may be removed and replaced without disconnecting aircraft power cables from the receptacle. Repair kits may include replacement pins and, optionally, replacement cover plates and related fasteners and tooling.
