正确说法

• 施工现场的临时供电完全依赖一台租借来的移动发电机，承包商每天都需要检查其燃油储量以防断电。(The temporary power supply at the construction site relied entirely on a rented mobile generator; the contractor needed to check its fuel level every day to prevent outages.)
• 作为城市备用电力系统的核心，这批新型发电机能够在主电网发生故障后的三秒内自动启动，为医院和数据中心等关键设施提供不间断供电。(As the core of the city's backup power system, these new generators can start automatically within three seconds of a main grid failure, providing uninterrupted power to critical facilities such as hospitals and data centres.)

错误说法

• 发电机坏了电没了 — too colloquial and imprecise for formal contexts; say 发电机发生故障导致供电中断 for technical or official communication
