Overview
McTech was contracted to perform a full assessment and preventative maintenance program for high-voltage substations and associated transformer assets at a copper mining and processing facility.
Challenge
The client needed to minimize unplanned downtime while extending asset life and ensuring compliance with mine safety and electrical standards. Access and scheduling had to align with production windows.
Solution
- Detailed condition assessment and thermal imaging of all critical assets.
- Scheduled maintenance windows with pre-staged materials and specialist crews.
- Transformer oil testing, tap changer inspection, and relay calibration.
- Documentation of findings and recommended lifecycle replacements.
Results
- All planned maintenance completed within agreed windows with no safety incidents.
- Identified and remediated potential failure points before they impacted production.
- Clear roadmap for future capital replacement and ongoing maintenance.
Scope
HV substations, power transformers, switchgear, protection relays, and associated HV/LV cabling and earthing.
