Project Overview
The client operates a 22 MVA transformer that is critical to plant continuity. Ageing
insulation, oil level inconsistencies and missing test records were raising the risk of
unplanned outages. ElectroCore Arabia was engaged to restore reliability through a
single, coordinated maintenance programme.
The Challenge
- Degraded oil quality and rising moisture content
- Gasket and valve leakages at multiple points
- No recent electrical test baseline for decisions
- Tight shutdown window to limit production loss
Our Solution
Our engineers planned the shutdown, filtered and dried the oil on site, arrested every
leak and ran a full suite of electrical tests before re-energising.
- Hot oil filtration and dehydration
- Leakage arrest and gasket replacement
- Insulation resistance, ratio and winding resistance tests
- Final report with recommendations
Our Process
Inspection
Site survey and condition assessment of the unit.
Oil Filtration
On-site purification to restore dielectric strength.
Leak Repair
Sealing and gasket replacement at all leak points.
Testing
Full electrical tests and handover report.
