Abstract: An electrical supply system for an aircraft includes a generator having a neutral point, an AC network, a bipolar DC network, and a neutral point clamped converter. The neutral point is connected to ground, in at least one operating mode. The converter has an AC side with AC connectors couplable with at least one phase of the generator. The converter also has a DC side with a first DC connector, a second DC connector and a neutral DC connector. The AC side of the converter is coupled with the generator, the DC side is coupled with the bipolar DC network, and the neutral DC connector is connected to ground. The convertor provides a DC voltage on the DC side upon receiving an AC voltage on the AC side, and provides an AC voltage on the AC side upon receiving a DC voltage on the DC side.

Abstract: A high voltage conductor for transmitting high voltage is provided. The high voltage conductor includes a power wire, a fault detection unit, and a monitoring unit. The power wire is configured for transmission of electrical energy. The fault detection unit is configured for detecting an electromagnetic field emanated by the power wire, and the monitoring unit is configured for detection of degradation in an isolation of the high voltage conductor. The monitoring unit is connected to the fault detection unit and is configured to receive an electrical signal induced in the fault detection unit, which electrical signal is induced as a result of a degradation of the isolation of the high voltage conductor. Thus, degradation of the isolation of the high voltage conductor may be recognized at an early stage.
