The authors present a novel on-line partial discharge (OLPD) high voltage (HV) insulation condition monitoring (CM) solution for complete HV network monitoring of petrochemical refining facilities. Continuous, (24/7) OLPD insulation monitoring of the HV insulation condition of cables, switchgear, transformers and rotating machines (operating at 3000 V and above) provides operators with an early warning...
The majority of the larger (> 7.5 MW) high voltage (> 3.3 kV) motors in the oil and gas industry are operated through variable speed drives (VSDs). In order to maintain the availability of these critical machines, on-line condition monitoring (CM) technology is required. This paper describes a novel solution for reliable, on-line partial discharge (OLPD) CM of the HV stator winding insulation...
