- Conducted Emissions Feedback from VSD-Operated ProductsThe ubiquitous increase in the use of mains power switching devices has been paralleled by the increase in nuisance tripping of GFCIs and other protection devices. Nuisance tripping can be identified to contain such high frequency signals and these must be properly taken into account when designing proper GFCI operation in this environment.
