In the first , the paper study the short duration variations of rms and discuss the voltage sag emphatically . this thesis put up a new definition of voltage sag , which confirm the duration precisely
本文首先研究了短时电压变动现象，对电压凹陷标准进行了较深入的讨论，提出了一种新的电压凹陷定义。
Voltage regulation : voltage regulation is maintained to within the limits of 1 % at any fixed load , and 2 . 5 % from no load to full load ( 0 . 8pf ) . ( special request is available option )
电压变动率：采用固态自动电压调整器，在任何固定负载下，其变动率保持在1 %以内。由无载至满载（ 0 . 8pf ）其电压变动率保持在2 . 5 %以内（可依要求做更精密设计）。
