本文分析表明,同步电动机的稳定界限是反时限特性。
The analysis of this paper shows that margin of stability of synchronous motor is of inverse time -lag.
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;
The inverse time delay characteristic is adopted by the basic zero-sequence over-voltage protection.
因此,作为失步保护后备的低电压保护也应具有反时限特性。
Thus, low voltage protection devices, served as lock-out protection reserve will also have characters uf inverse time-lag.
