Project details
This project covers several maintenance operations: testing of 225 kV circuit breakers at Dakhla substation, maintenance of TP/TS ventilation motors, and in-depth diagnostics on a transformer at Afourar substation. The aim of these operations is to guarantee the reliability of protection systems, ensure correct thermal operation, and anticipate any equipment failures.
- Testing of 225kv circuit breakers at DAKHLA substation
- TP/TS fan motor maintenance.
- Afourar transformer diagnostics.
Challenges
- Restricted access to the Dakhla substation during the test window.
- Severe fouling of fan motors affecting cooling.
- No recent history of the Afourar transformer.
Solutions
- Advance planning with network shutdown validated by local operator.
- Complete cleaning, filter replacement and thermal performance tests.
- On-site surveys and reconstruction of critical operating data.
