On-line Partial Discharge Condition Monitoring - A Smart Solution to Falling Oil Prices

In response to the reduction in global demand, investment in oil exploration has been drastically reduced, with the industry now focusing on maximising profitability from existing assets and minimising costs by increasing efficiency. Maximising uptime while minimising investment in equipment is now at the forefront of operator strategy. Reducing outages and overall downtime requires a more pragmatic approach to maintenance.
