The Jiangsu sunel large generator transformer, modular generator transformer, generator overvoltage, overcurrent, frequency, oil level and oil pressure, start the battery voltage protection.
Transformer speed off, over current, overload, zero sequence current, over temperature, differential, (oil-cooled transformers there are gas protection) protection. Generator transformer unit
differential protection phenomenon is short-circuit fault exists within the scope of protection, the instant action in the trip, shut down, de-excitation, alarm.
