Abstract
A power distribution system can include a power source, a power distribution unit, and at least one electrical load supplied by the power distribution unit. A detection circuit can be utilized in the power distribution system to sense or detect the occurrence of an electrical failure within the power or electrical unit.
Claims20
A power distribution system, comprising:
- a chassis defining an inner surface and an interior, and wherein at least a portion of the inner surface includes a conductive detection layer;
- at least one power distribution component received within the interior and configured to supply power from a power source to an electrical load and disposed within the interior;
- and
- a fault detection circuit comprising:
- a voltage sensor configured to sense a voltage at the conductive detection layer;
- a controller module communicatively connected with the voltage sensor and configured to receive the sensed voltage at the conductive detection layer, to compare the sensed voltage to a threshold value, and upon satisfaction of the comparison, to indicate an arcing event between the at least one power distribution component and the conductive detection layer of the chassis has occurred.

A method of operating a power distribution system, the method comprising:
- sensing, by a voltage sensor, a voltage at a conductive detection layer disposed on an inner surface of a chassis housing at least one power distribution component;
- receiving, by a controller module, the sensed voltage from the voltage sensor;
- comparing, by the controller module, the sensed voltage to a threshold voltage value;
- and
- upon satisfaction of the comparing, disable a supplying of power from a power source to the at least one power distribution component.
