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，過電壓欠電壓保護，過流保護等等。 - 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.
電容器母線電壓因含有諧波而發生畸變，因此在過電壓保護時要分別計算實際的電壓有效值和峰值。
