設(she)(she)置功(gong)(gong)(gong)(gong)能(neng)(neng)：CT變比、保護定值、延時(shi)時(shi)間、功(gong)(gong)(gong)(gong)率因數(shu)等設(she)(she)置 控(kong)制(zhi)(zhi)功(gong)(gong)(gong)(gong)能(neng)(neng)：自動、手動控(kong)制(zhi)(zhi)，根(gen)據(ju)受控(kong)物理量（無(wu)(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率、無(wu)(wu)功(gong)(gong)(gong)(gong)電(dian)流、功(gong)(gong)(gong)(gong)率因數(shu)、時(shi)段）自動投、切控(kong)制(zhi)(zhi)。容量相(xiang)同的電(dian)容器循環投切，容量不同的按無(wu)(wu)功(gong)(gong)(gong)(gong)缺額選擇投切；投切前，對(dui)投切產生(sheng)的無(wu)(wu)功(gong)(gong)(gong)(gong)和電(dian)壓變化進行預(yu)(yu)測(ce)，如預(yu)(yu)期投切后需要(yao)逆向操作則不再投切。 測(ce)量功(gong)(gong)(gong)(gong)能(neng)(neng)：配電(dian)電(dian)壓、電(dian)流、功(gong)(gong)(gong)(gong)率因數(shu)、有(you)功(gong)(gong)(gong)(gong)/無(wu)(wu)功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率、諧波含(han)量測(ce)量。 信(xin)號功(gong)(gong)(gong)(gong)能(neng)(neng)：電(dian)容器投運(yun)、退運(yun)信(xin)號、產品本身或外
功能特點:
設(she)置功(gong)能：CT變比、保護(hu)定值、延時(shi)時(shi)間、功(gong)率因數(shu)等設(she)置
控(kong)(kong)制功能：自動(dong)(dong)、手(shou)動(dong)(dong)控(kong)(kong)制，根(gen)據受控(kong)(kong)物理量（無(wu)功功率(lv)、無(wu)功電(dian)流、功率(lv)因數、時段）自動(dong)(dong)投(tou)(tou)(tou)(tou)、切(qie)(qie)控(kong)(kong)制。容量相同的電(dian)容器循環投(tou)(tou)(tou)(tou)切(qie)(qie)，容量不同的按無(wu)功缺額選(xuan)擇投(tou)(tou)(tou)(tou)切(qie)(qie)；投(tou)(tou)(tou)(tou)切(qie)(qie)前(qian)，對投(tou)(tou)(tou)(tou)切(qie)(qie)產生(sheng)的無(wu)功和電(dian)壓變化進行(xing)預測，如預期投(tou)(tou)(tou)(tou)切(qie)(qie)后需(xu)要逆向操作則不再投(tou)(tou)(tou)(tou)切(qie)(qie)。
測(ce)量(liang)功(gong)能：配電電壓、電流(liu)、功(gong)率(lv)因數、有功(gong)/無(wu)功(gong)功(gong)率(lv)、諧波含(han)量(liang)測(ce)量(liang)。
信號功能(neng)：電容器投(tou)運(yun)、退(tui)運(yun)信號、產品本(ben)身或外設故(gu)障信號
