A patented compensator automatically adjusts the valve position to holdconstant outlet pressures at all flow rates.
专利补偿器自动调整阀的位置来保持任何流速下的出口压力。

Varies the generator terminal voltage in accordance with its load to holdconstant voltage at some point electrically remote from the generator, such as the station high voltage bus.
按发电机的负荷改变发电机的端电压使远离发电机的某一电气点如变电站高压母线的电压稳定不变。
