Project details
This project involves the modernization and maintenance of high-voltage equipment at LYDEC source substations. It includes specific technical actions carried out at various sites, to guarantee operational reliability, service continuity and compliance with current standards.
- Layout of power transformers in the lydec source substation
- Layout of power transformers in the lydec source substation
- Renewal of protective relays on HV switchboards at Dar Bouazza, Ain Harrouda and ADE source substations
- Overhaul of 72KV and 225KV circuit breakers in lydec source substations
Challenges
Obsolete protection relays, calibration difficulties and incompatibility with current standards.
Thermally stressed transformers, need for oil treatment to prevent insulation losses.
Restricted access to equipment, longer response times and multi-site logistics management.
Solutions
Moderate protection relays, readjustment for optimum compliance.
Transformer oil treatment, vacuum dehydration to prevent loss of insulation.
Verification of HV equipment, analysis and preventive replacement of critical components.
