1. Reasonable setting combining a model parameters, low voltage protection and clamping force.

2. Introduces the constitutes of low voltage protection system of distributing transformer, analyzes the failure reason, puts forward concrete measures of improving low voltage protective reliability.

3. Thus, low voltage protection devices, served as lock-out protection reserve will also have characters uf inverse time-lag.Sentence dictionary

4. Protective circuits with multilevel, low voltage protection level and excellent capability of safety.

5. The electronic unit has a low voltage protection system built in.

6. Low voltage protection devices in China have characters of fixed time-lag.

7. In the process of running, the governor has the function of over-current protect, low voltage protection, output short-voltage protection and soft start.

8. Over current protection, negative current protection, zero sequence current protection, over time of start protection and low voltage protection is configured in the device.

9. When voltage is very low or power supply has been broken off, it will result in action of low voltage protection device so as to remove load.

10. The controller will detect the battery voltage and gradually reduce the maximum current limit according to the different voltage levels until the low voltage protection potion.
