Partial Discharge testing
Partial Discharge testing
(OP)
Hi,
What is the minimum network voltage where partial discharge may occur? I am led to believe it is approx. 5kV but cannot find documentation to support this. We have had a query raised regarding PD testing on 3.3kV switchgear but at the moment don't think this is required. Any advice would be appreciated.

RE: Partial Discharge testing
Having said that, 3.3kV would be pretty close to the inception voltage and PD testing probably isn't warranted. Anyway, IEC 62271-200 (2003) Annex B1 talks about how PD testing is only really appropriate for metal-enclosed switchgear / controlgear with organic insulating materials or fluid-filled compartments.
