French to English Tech/Engineering Mechanics / Mech Engineering

A generator installed on a power plant. Unfortunately, I can't provide any more context as the document I'm translating is in fact a legal document concerning an insurance issue, i.e. who should pay out due to the fact that cracks appeared in the generators. I will shortly post a second question for a very similar term if you wouldn't mind looking out for that too in case you're able to help on both terms. Thanks in advance!
