alternator pitch

rizvi110

hi all,

please provide me the info that what is the maximum allowable pitch difference for synchronizing of DG Sets having different pitch?

jim hardy

since pitch affects the waveform not the frequency, why would pitch matter for synchronizing?

They might circulate some harmonic currents but you'll be hard pressed to detect that from the panel meters. And the amount will depend on the excitation and the impedance connecting them, and probably the external load too.

Perhaps i dont understand the issue prompting your question.
