Brush a good sign generator brushes should be a good marker for the use of performance: a commutator or collector ring surface can quickly form a layer of uniform, moderate and stable oxide film. b brushless long life, do not wear commutator or collector ring. c carbon brush commutation with good flow properties and set the spark inhibition within the allowable range diesel diesel generator set, and the energy loss is small. d Brush runtime, but the thermal generators, low noise, reliable assembly, is not damaged. Drying Cummins generator sets new synchronous generator installed in the trailer before running silent generators, generally should be dried. If the insulation resistance to meet the requirements, can not be dried, but the load operation start 24h preferably does not exceed 50% of the rated capacity. When all the running Cummins diesel generator set shut down for maintenance or downtime exceeds the limit, the insulation resistance below the specified value must be dried. Such as determining the surface damp, you can use with a load-drying method for drying. All because of flooding or wet steam generator pipes leak and must be dried.
