Diesel generator oscillation loses synchronization characteristics
1) When the stator current exceeds the normal value, the ammeter pointer will violently bump.
2) The pointer of the stator voltmeter will swing quickly.
3) The active power meter pointer swings on the entire dial of the dial.
4) The rotor ammeter pointer oscillates rapidly around the normal value.
5) The generator emits a chirping sound, and the change of the calling sound corresponds to the swinging frequency of the meter hand.
6) The instruments of other generators running in parallel also have corresponding swings.
