You should know that there are the most thunderstorms in summer, but it cannot be ruled out that lightning at other times can cause faults to the generator set. How to prevent lightning and reduce losses? The generator set company will give you a detailed discussion.
The specific lightning protection method for generator sets should be based on the size of the generator set capacity, the strength of local lightning activities, and the requirements for power supply reliability. Theoretical and practical evidence has shown that for generator sets connected to overhead transmission lines through transformers, as long as the transformer is reliably protected, there is usually no need to adopt lightning protection methods for the generator set. In areas with high lightning, especially important generator sets without overhead direct wiring, to prevent lightning waves on the high-voltage side of the transformer from passing through the transformer and endangering the insulation of the generator set, it is advisable to install a set of magnetic blowing lightning arresters on the output line of the generator set. The generator set directly connected to the overhead distribution line must undergo lightning protection, and different lightning protection measures should be taken for the insulation of the generator set according to the national standard design specifications and different situations. The lightning arrester used to protect high-voltage rotating motors is usually a magnetic blowing lightning arrester, which should be installed near the generator set. In general, lightning arresters can be installed at the outlet of the motor. If there are no more than two generator sets connected to each group of busbars, or if the single unit capacity does not exceed 500kw and the distance from the lightning arrester does not exceed 50m, the lightning arrester can also be installed on each group of busbars. When the neutral point of the direct distribution motor can be led out and is not directly grounded, magnetic blowers or ordinary valve type lightning arresters should be installed on the neutral point. The rated voltage of the lightning arrester should not be lower than the maximum operating phase voltage of the generator set. For line kV generator sets, FCD-4 or FZ-4 4kV lightning arresters should be selected. A 10.5kV generator set should use FCD-6 or Fz-6 6kV lightning arresters.
