Key Activities:

1. HT MT Transformer Testing:
   We are ensuring the optimal performance of the HT MT transformers by conducting various tests to verify energy transfer efficiency, including:

   • Transformation Ratio Measurement: To verify the voltage transformation capabilities.
   • Winding Resistance Tests: To assess primary and secondary winding resistance.
   • Short-Circuit Impedance and FRSL: Ensuring safe operational limits and effective fault response.
   • Capacitance and Dissipation Factors: Testing of bushings and windings to ensure reliability.
   • Insulation Resistance: Checking the integrity of windings and protection systems.
   • Functional Tests of Protection Devices and Cooling Systems: Ensuring that all internal systems work as expected under load conditions.

2. HT Circuit Breaker Testing:
   We’re reinforcing the circuit breaker systems that protect the infrastructure by conducting the following critical tests:

   • Opening and Closing Time Measurements: Ensuring timely operations of each pole.
   • Peak Current Measurements: For the opening/closing coils to confirm accurate performance.
   • Contact Resistance: Checking each pole for optimal conductivity and protection.
   • Circuit Breaker Insulation: Ensuring the insulation meets safety standards.
   • Inrush Current and Spring Mechanism Charging Time: Verifying that the spring mechanisms charge within the expected time frame.

3. Relay Protection Testing:
   To ensure the safety and reliability of the system, our team is performing:

   • Relay Settings and Functionality Checks: Verifying the calibration and operation of relays.
   • Primary and Secondary Injection Tests: Confirming the proper functioning of relay systems.
   • Coordination and Time Delay Assessments: Ensuring proper coordination between protection devices.
   • Tripping and Alarm Circuit Tests: Ensuring that alarms and trip mechanisms function during fault conditions.

Outcomes:

Through these rigorous tests and commissioning processes, SSE MENA is contributing to the overall reliability, safety, and efficiency of the power systems in Agadir. Our work ensures that Aman El Baraka (Grupo Cox) can depend on a robust power infrastructure that meets the highest standards of operational safety and performance.
