  • A Closer Look at Air Gap Eccentricity - Reliabilityweb: A

    Eccentricity peaks cannot be harmonics of line frequency. As a result of slip being involved, the calculation of eccentricity prevents it mathematically from being a multiple of the line frequency. Therefore, running the harmonics marker, which places a small green x at each of the line frequency harmonic peaks, allows you to quickly remove the
