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.
