Do you provide on-site maintenance and repair services?
Yes. Our lifecycle services division offers installation supervision, commissioning, preventive maintenance, oil analysis, repairs (on-site and factory), retrofilling (mineral oil to ester conversion), and 24/7 emergency response. We service transformers of any make or model.
ETS's Lifecycle Services division provides comprehensive support from installation through to end-of-life, regardless of transformer manufacturer. Our field service teams are deployed across the GCC, East Africa, and have project-based capabilities in North America and South Asia.
Installation & Commissioning
- Receiving inspection and damage assessment
- Oil filling, processing, and degassing
- Electrical testing (ratio, IR, PI, winding resistance)
- Energisation supervision and load acceptance
- Commissioning report with baseline measurements
Preventive Maintenance
- Annual inspection and maintenance per IEEE C57.12.00 / IEC 60076
- Oil sampling and DGA (Dissolved Gas Analysis) interpretation
- Thermal imaging of bushings, connections, and radiators
- Partial discharge screening
- Tap changer maintenance and contact inspection
- Gasket inspection and tightening
Corrective Services
- On-site oil treatment (degassing, dehydration, filtration)
- Bushing replacement
- Gasket replacement and leak repair
- Tap changer overhaul
- Winding repair and replacement (factory-based)
- Complete transformer overhaul and refurbishment
Retrofilling: Conversion from mineral oil to ester fluid — improving fire safety and environmental performance of existing assets without replacement.
24/7 Emergency Response: Our emergency hotline provides rapid mobilisation for transformer failures, with field engineers available across the region.
