GOEK SF6 Bushing Failure vs online monitoring system

[Ysaac]

Does anybody know something about NOT TO BE RECOMMENDED to use bushing monitoring system through capacitive tap in transformer connected to an GIS? The restriction I'm talking about would be due the relationship between VFTO and the impedance add to the bushing tap.

Thanks

I am not aware of VFTO getting affected by any impedance connected to bushing test tap.

@prc
What I mind is the bushing been more aggressive affected by VFTO than it would be without the impedance connected on the capacitive tap.

To my knowledge, no.
