Abstract

1508793 Cores for dynamo-electric machines REYROLLE PARSONS Ltd 1 April 1975 [2 April 1974] 14663/74 Heading H2A An electromagnetic machine laminated core comprises laminations 1 insulated from each other, at least a majority of the laminations also being insulated from earth, and a plurality of conducting plates 2 inserted into the core at intervals along its length, the plates being connectible to earth to minimize the rise in potential of the laminations above earth. The plates may be connected to earth directly or through impedances such as resistors 4. A supervisory or protective device 9 may be used to sense the voltages across the impedances to give an indication of a fault in the machine.
