Abstract:
1. A hydrogenerator plant for connection to a high voltage transmission or distribution network comprising: at least one rotating electric machine for high voltage coupled to a turbine via shaft means, said electric machine comprising at least one winding formed of a conductor including a plurality of insulated conductive elements, and at least one uninsulated conductive element; a covering surrounding the conductor including an inner layer having semiconducting properties, a solid insulating layer surrounding the inner layer and an outer layer having semiconducting properties surrounding the insulating layer, said inner layer being in contact with the uninsulated element such that the inner layer has the same potential as the conductor, and said at least one winding being directly connectable to the transmission or distribution network, the voltages being across a range of transmission or distribution voltages.
