- 3. Periodic portable thermal imaging camera Covering Your Substation Assets 3 • Analog Gauges: analog outputs, log readings • Visual Indicators and sight glasses • Shifty log readings looking for physical wear and broken parts • Assets over 40 years old, overdesigned and heavily loaded to 100% nameplate or higher • Aged workforce, in general less experienced • Manual samples, manual analysis, manual interpretation. OLD SUBSTATION Portable Partial Discharge Monitoring Manual oil samples
- 4. Covering Your Substation Assets 4 • Solid state sensors with intelligence • Data concentrator to pull data together from multiple sensors • 10-fold increase in sensors, 1,000-fold increase in data • Assets designed to nameplate and loaded 75-100% NEW SUBSTATION Continuous Online Thermal Imaging • More remote, less local • Most assets under 20 years old • Aged workforce, in general less experienced
- 5. Thermography Inspections 5 General Comments Motivation and “Trends in Asset Management” How do utilities balance maintaining “security of supply” while reducing costs and increasing value Early detection of failing assets? Initiatives in CBM? Provide “remote” access to substations? Data collection and analysis initiatives? “Expert” systems? Protect critical assets or grid points?
- 6. Thermography Inspections 6 Thermography Inspections Infrared thermography has been proven as an effective way of detecting and diagnosing electrical equipment faults. However… manual & periodic inspections have limits: Costly Requires trained staff and time Inconsistent Results can be highly variable depending on weather and loading conditions Data Analysis Limited in methods and qualified experts to analyze measurements Errors Manual inspections are error-prone
- 7. Thermography Inspections 7 Benefits and Goals of Asset Management Operating benefits • Reduce unanticipated failures • Better manage contingencies, improve reliability • Optimize grid utilization Planning – Prioritize and justify replacement Maintenance benefits • Focus effort where needed and extend resources • Inform crew of condition & prepare material before truck rolls • Reduce number of trips to substation Safety benefit – know conditions & risk prior to site visit Environmental benefit – prevent discharges and clean-up Save capital ($$) • Reduce unexpected failures and associated collateral damage • Extend life of old but healthy assets Reduce O&M costs for unnecessary maintenance & inspections
- 9. — Automated Substation Thermal Imaging • Enables continuous infrared thermography & visual monitoring 24/7 • Early and remote fault detection • Continuous monitoring without manpower constraints • Remotely monitor multiple, distant substations from central location • Automated data analysis • Integrates into existing communications network
