OLPD Condition Monitoring of Complete Networks for Oil and Gas: Challenges and Solutions Explained through Case Studies

This paper provides an overview of the development and case studies from installations of On-line Partial Discharge (OLPD) Condition Monitoring (CM) systems for complete MV and HV networks in the Oil and Gas industry.

On-line Partial Discharge (OLPD) Testing and Monitoring Strategies for Oil and Gas HV Assets

On-line Partial Discharge (OLPD) condition monitoring (CM) refers to the diagnostics of the high voltage (HV) insulation of in-service HV cables and plant in the voltage range of 3.3kV and above.

On-Line Partial Discharge Condition Monitoring of Complete HV Networks in the Oil & Gas Industry

A technique is presented for the on-line partial discharge (OLPD) insulation condition monitoring (CM) of complete high voltage (HV) networks in the oil & gas industry.

A Holistic Combined Electrical and Mechanical Condition Monitoring Technique for Oil and Gas High Voltage Rotating Machines

A new holistic technique for the combined electrical and mechanical condition monitoring (CM) of high voltage (HV) rotating machines has been developed.

On-line Partial Discharge (OLPD) Insulation Condition Monitoring Solutions for Rotating High Voltage (HV) Machines

This paper presents a review of the sensor and monitoring options available to oil & gas operators for the on-line partial discharge (OLPD) insulation condition monitoring (CM) of in-service rotating high voltage (HV) machines.

On-Line Partial Discharge (OLPD) Insulation Condition Monitoring of Complete High Voltage (HV) Networks in the Oil & Gas Industry

The authors describe a new approach to on-line partial discharge (OLPD) insulation condition monitoring (CM) of complete high voltage (HV) networks (voltage range: 3.3 kV to 132 kV) in the oil & gas industry. The technique described is suitable for the condition monitoring of HV generators, switchgear, cables, motors and transformers. Comprehensive HV network OLPD condition monitoring coverage is achieved through the use of wideband, OLPD sensors and continuous monitors located at the central switchboards of the facility.

Continuous, Remote On-Line Partial Discharge (OLPD) Monitoring Of HV Ex/Atex Motors In The Oil And Gas Industry

The work described in this paper is a continuation of that carried out by the same authors, as reported at the IEEE-PCIC 2012 conference, presenting results from the continued application of a new technique for the remote, on-line partial discharge (OLPD) testing and monitoring of in-service, high voltage (HV) Ex/Atex motors operating in hazardous gas zones.

A New Technique for The Remote Partial Discharge Monitoring of The Stator Insulation of High-Voltage Motors Located In “Ex” (Hazardous) Locations

The authors present a paper on the application of a new technique for the remote on-line PD monitoring of the stator insulation condition of in-service, high voltage rotating machines. A case study from a recent pilot project (August 2011) where the new remote PD monitoring measurement techniques were successfully trialed to measure PD activity of in-service 10 kV motors in an oil processing facility is also presented.

Remote Monitoring of Partial Discharge Activity within High-Voltage Rotating Machines in Hazardous Locations

The authors report on preliminary results from PD testing carried out on in-service 10 kV motors which show how different areas of PD activity occurring within the stator windings of the motors can be reliably measured by placing wideband High Frequency Current Transformer (HFCT) sensors at the switchgear end of the supply cable.

On-Line Partial Discharge Testing of In-Service Rotating Machines in Ex Hazardous Environments by Employment of Central Monitoring Solutions

The new PD measurement and monitoring techniques outlined in this paper are carried out at the switchgear-end of the machine's feeder cable, at distances of up to 2 km from the machine under test. The authors present case studies from two oil & gas companies showing how the techniques have been used for monitoring PD of in-service motors located in Ex zones.
