柴油发电机组油雾保护系统的优缺点：
该保护装置的快速性、灵敏性无可厚非，但经过几年的运行检修发现，由于外界或装置自身的原因，使得其选择性和可靠性大大降低。比如由于润滑油冷却器的泄漏（水进入并污染了润滑油），油雾探测器将会感受到由于水份的增加而引起的不透明度的增加，继而发生跳机。油雾探测器的电子元件属于高精度元件，但因其安装在柴油机本体上，温度高、振动大，工作环境极为恶劣，由此使得电子元件的老化加剧，产生温度漂移，跳机的灵敏度增加，误动率也增加。而且该保护有时出现指示灯全无指示，使得保护经常处于脱离状态等。频繁的保护误动及保护的无法就绪，不仅会造成因甩负荷而引起的材质疲劳，寿命缩短，而且会使生产人员产生麻痹心理，认为该装置不可靠，是误动，这样大大限制并误导了生产人员的思维，而在真正出现“高油雾”时就会发生事故。
Advantages and disadvantages of oil mist protection system for diesel generator set:
The speed and sensitivity of this protective device are understandable, but after several years of operation and maintenance, it has been found that due to external factors or the device itself, its selectivity and reliability have been greatly reduced. For example, due to leakage of the lubricating oil cooler (water entering and contaminating the lubricating oil), the oil mist detector will feel an increase in opacity caused by the increase in moisture, leading to machine trip. The electronic components of the oil mist detector belong to high-precision components, but due to its installation on the diesel engine body, the temperature is high, the vibration is large, and the working environment is extremely harsh, which exacerbates the aging of the electronic components, generates temperature drift, increases the sensitivity of engine tripping, and increases the false alarm rate. And sometimes the indicator light of the protection is completely off, causing the protection to frequently be in a disengaged state. Frequent protection misoperation and inability to prepare protection not only cause material fatigue and shortened lifespan due to load shedding, but also create a paralyzing mentality among production personnel, thinking that the device is unreliable and is misoperated. This greatly limits and misleads the thinking of production personnel, and accidents can occur when "high oil mist" actually occurs.
