مهندس تصميم كهربائي

Main responsibilities.

Depending on your area of ​​expertise, your responsibilities may include:

• Carry out the conceptual, preliminary and detailed electrical design of electrical substations, transmission networks and electrical infrastructure.
• Develop and revise single-line diagrams, protection diagrams, control diagrams, layout plans and electrical drawings.
• Define the system architecture and electrical design principles.
• Perform network studies: power flow, short circuits, stability, harmonics, reactive power and network connection.
• Size the electrical equipment and perform the technical calculations.
• Design of HV/EHV substations with air insulation (AIS) or gas insulation (GIS), including the placement of primary equipment and their interfaces.
• Specify transformers, circuit breakers, disconnectors, instrument transformers, busbars and other HV equipment.
• Conduct studies on grounding, insulation coordination and electrical clearances.
• Designing protection and control systems, defining protection philosophies, relay settings and coordination studies.
• Develop SCADA and workstation automation architectures, including RTU/IED integration and IEC 61850 interfaces.
• Conduct engineering studies related to HVDC, SVC, STATCOM and FACTS technologies.
• Designing overhead HV/EHV lines: choice of conductors, insulation, electrical clearances, grounding and electrical parameters.
• Prepare technical specifications and procurement requirements, evaluate submissions and review supplier documentation.
• Perform network modeling and simulations using specialized tools.
• Participate in design reviews and coordinate interfaces with civil, structural, mechanical, telecommunications and control engineering teams.
• Resolve technical issues and ensure compliance with utility standards, network codes and customer requirements.
• Provide technical support to the procurement, construction and commissioning teams.

Areas of specialization

Candidates must possess solid expertise in at least one of the following areas:

1. Protection and control
