Feeder Resonance

Read about the feeder resonance approximation formula and how to apply it.Feeder Resonance_04


The feeder resonance approximation formula (4) is easily calculated from readily available system information.


The derivation of this formula is presented here.


A resonance frequency check should be performed any time there’s a change in PFC values, or if oscillatory transients are creating problems for customers or switching equipment...
