What Are The Protection Measures For Generators

1. Overload protection When the generator is overloaded, the system will automatically send a signal and stop power supply.
2. When the lack of phase protection When any phase of the three -phase AC power supply is disconnected or short circuit, the system will automatically cut off the output current of the phase.
3. When the lack of voltage protection is lower than a certain value of the rated voltage (such as 15%), the system will automatically cut off the output current of the phase.
4. Excessive temperature Protective device can prevent the impact of excessive environmental temperature or too low on the unit;
5. The speed control system has the characteristics of the speed closed -loop adjustment. When the speed exceeds the set value, it can be performed until the stop;
6. The grounding detection system determines whether the ground failure has occurred and a corresponding treatment instruction is made by the insulation resistance between the monitoring case and the stator winding;
7. Frequency loss and blocking protection device can prevent the occurrence of units caused by frequency fluctuations;
8. The inverse power control device can limit the size of the excitation surge to reduce the degree of damage to the crew.
