Why should the generator house be clean and the floor free of sand?
RE:If the diesel engine inhales dirty air, the power will drop; if the generator inhales impurities such as sand, it will cause insulation damage between the stator and rotor gaps, causing heavy burning.

Why do we ask our customers to do a fastening of all electrical contacts after every 200 hours of operation?
RE:The diesel generator set is a vibration worker. Moreover, many domestically produced or assembled units should be useless with double nuts. The use of the spring washer is useless. Once the electrical fastener is loose, a large contact resistance is generated, which causes the unit to operate abnormally.

What is the power factor of a three-phase generator? Can I add a power compensator to improve the power factor?
RE:The power factor is 0.8. No, because the charging and discharging of the capacitor will cause fluctuations in the small power supply. And the unit oscillated.

What are the conditions for the parallel use of two generator sets? What device is used to complete the parallel operation?
RE:The condition for parallel use is that the voltage, frequency and phase of the two machines are the same. Commonly known as "three simultaneous." Use a dedicated parallel device to complete the parallel operation. It is generally recommended to use fully automatic and cabinets. Try not to manually parallel. Because the success or failure of manual parallelism depends on human experience. The author has been vocal about more than 20 years of experience in electric power work. The reliable success rate of manual paralleling of diesel generators is equal to zero. It is never possible to apply a small power system with the concept of manual parallel power supply for the mains power system, because the protection levels of the two are completely different.
