over-voltage relay的用法和樣例：
例句
- And also, it has many other functions include islanding detection and avoiding, over voltage protection, over current protection and so on.
此逆變器還具有其他功能，包括孤島效應，過(guò)電壓欠電壓保護，過(guò)流保護等等。 - Capacitor bus voltage is distorted due to harmonics, so both the r.m.s and crest values of the waveform should be measured in the over-voltage protection.
電容器母線(xiàn)電壓因含有諧波而發(fā)生畸變，因此在過(guò)電壓保護時(shí)要分別計算實(shí)際的電壓有效值和峰值。
