Over current protection, negative current protection, zerosequence current protection, over time of start protection and low voltage protection is configured in the device.
本装置配有过流保护、负序电流保护、零序电路保护、起动时间过长保护、低电压保护。
2
The inverse time delay characteristic is adopted by the basic zero-sequence over-voltageprotection.
其基本保护采用零序过电压保护，动作时间采用反时限特性；
3
A novel principle of negative-sequence current compensation based adaptive zero-sequence over-voltageprotection is therefore proposed.
