Monitor medium-voltage switchgear in refineries

Scope of The ProblemRefinery Power ConcernsMVS IssuesManual InspectionsThermal MonitoringPartial Discharge MonitoringUHF Partial Discharge DetectionContinuous MonitoringTakeawayRefinery power outages have been in the news over the last few years. In January, a sitewide power outage at ExxonMobil’s refinery in Beaumont, Texas required operators to empty systems by burning product, wasting 365 Mbpd of crude oil. The burning created large flames and plumes of black smoke that drifted over nearby neighborhoods.1 According to the Billings Gazette, the city of Billings, Montana has been pulled into an ongoing lawsuit between ExxonMobil and NorthWestern Energy that was filed by the oil corporation after two power outages disrupted its Billings refinery.2In January, ExxonMobil sued NorthWestern for refinery outages in 2014 and 2016 that led to excess flaring. ExxonMobil claims the outages cost the company millions of dollars, and it is seeking undisclosed damages in the lawsuit. In February, a California federal jury found Pacific Gas and Electric (PG&E) negligent and partially to blame for a power outage at Tesoro’s Martinez, California refinery, and ordered PG&E...Get price
