電壓過高,斷路開關裝置可感應而關閉電源,遇電壓過低,可否用斷路開關裝置?我所知道有某些牌子可用於遇電壓過低時,可感應而關閉電源,請問:
(1) 有否其他方法可行?
(2)如有斷路開關裝置可幫助遇電壓過低時關閉電源,可否介紹某些牌子及功能?
謝謝

✔ 最佳答案
試下以下產品，我用過，唔錯，過電壓 / 欠電壓 繼電器 80V ~ 277V 可調式

For 380V supply system..
the GEC, MVTU is under-volt protection relay between 2-phase.
MWTU for power phase reverse protection..
for over-volt protection, same MVTU..
All GEC product is very common in Gen-set supply control panel.
For supply main switchboard. Power failure relay.. GEC, 3-phase input electronic relay is very common..the accurate lower than MVTU..relay.
Gen-set supply & switchboard supplier is to be choice the different model/ type of relay..
