ElectroCore Arabia conducted a comprehensive internal inspection of a power transformer at our Dammam workshop to identify and resolve the root cause of elevated partial discharge (PD) levels detected during routine testing. The project involved complete disassembly, detailed visual and dimensional inspection of all windings and insulation systems, and root cause determination with corrective recommendations.
Scope of Work
- Transformer transportation to ElectroCore workshop
- Complete oil draining and safe disposal
- Core and windings removal from transformer tank
- Detailed visual inspection of all winding insulation
- Dimensional check of winding geometry and clearances
- Insulation barrier and shield inspection
- Tap changer contact and mechanism inspection
- Bushing connection and lead inspection
- Partial discharge source identification and documentation
- Corrective repair plan and reassembly
- Post-repair testing (TTR, IR, SFRA, PD, BDV)
- Final commissioning and energization support
