| Abstract: | The following three factors have great influence in the safe operating system: Whether the generator commutator can work normally, Whether both high and low tension stand-by power can be used properly and safely, Whether the resistance of the electric grounded net can meet the standard and requirement. Based on this , this paper is mainly focused on the causes which make the machine out of the normal working system and also some major solutions to these problems are discussed and introduced clearly for the protection and repair. |
