Diesel generator set of fault and treatment method ---(1)

Diesel generator (electric) excitation-loss is how to return a responsibility, how should handle?
Generator (electric) long time need not, cause before delivery contains the remanent magnetization in core loss and excitation coil can't afford to build its magnetic field, engine functioning but not sent out the electricity at this moment, this kind of phenomenon, new or unused units more long time.
Processing method:
1. There are field excitation button button.
2. No excitation button, using battery for its magnetization.
3. Take a light bulb, overdrive for a few seconds.
