Hi
I would like the experts to help me understand the phenomenon of resistance and capacitance in an insulator. I asked the question in another forum but no body replied to my satisfaction.I found some other threads asking same question but no reply.
There are some insulators which are connected to a bus bar to ground.This bus bar is fed through a transformer with delta winding on the secodnary side. When the IR value of the bus bar is check with megger , it shows very high resistance( showing that the insulators are healthy).
When we check the open circuit voltage of the transformer each phase with respect to ground , the voltage shows unbalance ( as floating). As people say it depends on the ground capacitance.
what is the relation between resistance and ground capacitace of the insulators?
