Partial Discharges in Electrical Insulationsite.ieee.org/sas-pesias/files/2016/...Insulation.pdf· PDF fileOil Filled Transformer PD Testing •On-line PD (usually measured by acoustic sensors, by RFCTs on HV bushing tap or UHF antenna within the transformer) rarely used so far – false indications are common, thus credibility is low •PD can only occur in gas bubbles. Once PD occurs bubble usually disintegrates preventing further PD
List of HVDC projects - Wikipedia is a list of notable high-voltage direct-current power transmission projects. HVDC projects for long-distance transmission have two (or rarely, more) converter stations and a transmission line interconnecting them. Generally overhead lines are used for interconnection, but an important class of HVDC projects use submarine power cables. A ...
