Abstract
An electrical installation includes a high voltage power source having a first ground reference, and a low voltage power source having a second ground reference (21). A power unit of the electrical installation receives power from the high voltage power source and is conductively connected to the first ground reference. The installation also includes one or more peripheral units. At least one of the peripheral units receives power from the high voltage source and is conductively connected to the first ground reference. The first ground reference is galvanically isolated from the second ground reference. The power unit may include a motor drive for driving an electrical motor and may be installed in a vehicle.
