Abstract :
In the paper a generator protection As described which is capable of detecting earth leak-- ages in any point of the stator winding and deterioration of insulation over parts of the winding adjacent to the neutral point. The theoretical considerations in conjunction with the application or the protection have been dealt with in Paper 34-O1 of the 1972 session of CIGRE. In the present paper, after giving a description of the operating principle, an account of some recent results of development and experiments will be given.
