By David Clark, CMS Wind About 50% of drivetrain failures are in the generator, and they are predictable by months with the right detection. The failures are grouped into three specific categories: bearing-related, electrical-related and misalignments. Here we’ll discuss electrical fluting caused by an “ELF.” Stray electrical current is not a problem unique to wind.…
