Abstract: An apparatus and method for detecting current imbalance between two or more electrical energy distribution elements of an electrical energy distribution network are disclosed. Each of a plurality of temperature sensors are implemented by a temperature sensing section of an optical fiber arranged to produce, in response to an optical input signal, an optical output signal indicative of the temperature of the temperature sensing section. First and second temperature sensors of the plurality are in thermal contact with first and second electrical energy distribution elements, respectively, to determine first and second temperature characteristics thereof based on the respective output signals. A current imbalance between the first and second elements is detected based on a comparison of the first temperature characteristic with the second temperature characteristic.

Abstract: An aircraft including: a wing having a leading edge; an electric motor mounted on the wing; and an electric power cable in the wing for providing power to the electric motor, wherein the electric power cable runs through a duct in the wing; the duct comprises an air inlet and an air outlet; and the electric power cable is cooled by air passing through the duct between the air inlet and the air outlet.

Abstract: An aircraft is disclosed include wiring configured to carry electrical power; and an electromagnetic shielding arrangement which provides an enclosure around the wiring and is configured to block electromagnetic emissions from the wiring. The electromagnetic shielding arrangement includes a first shield; a second shield which can move relative to the first shield; and a gap between overlapping portions of the shields. The gap is configured to enable air to flow into or out of the enclosure via the gap.

Abstract: A vehicle, including a high voltage energy consumer; an electrical energy source; an electrical energy distribution network having an electrical energy distribution element configured to carry electrical power from the electrical energy source to the high voltage energy consumer; and a cooling system for cooling the high voltage energy consumer, the cooling system having: coolant, and a coolant distribution network having a coolant distribution element for delivering the coolant to the high voltage energy consumer to remove heat generated by the high voltage energy consumer; wherein the coolant distribution element provides mechanical support to the electrical energy distribution element, and the coolant within in the coolant distribution element removes heat generated in the electrical energy distribution element as it carries electrical power from the electrical energy source to the high voltage energy consumer
