As a Power System Protection Engineer in the Maintenance and Operation (MO) section, you will be responsible for the management of the overall lifecycle of protection relays, part of CERN's electrical transmission and distribution network, from design and procurement to commissioning and maintenance.

You will:

• Update and maintain the whole protection plan for CERN transmission and distribution network.
• Draw up technical specifications and all tendering documents for the implementation of the protection plan, in particular the purchase of protection relays, and manage related contract(s).
• Program and test protection relays configurations (logics).
• Assist the design office in preparing installation plans and calculating protection settings, through fault simulations in the network model.
• Lead the commissioning of protection relays on site (functional testing, current injections, troubleshooting) by preparing dedicated procedures and supervising commissioning operator(s).
• Elaborate a comprehensive preventive and corrective maintenance plan, including spare parts management and lead its implementation.
• Define the methodology to integrate the protection relays and the associated maintenance activities, in CERN Computerized Maintenance Management System.

Experience:

• Very good knowledge of modern equipment associated with complex high voltage electrical networks (400 kV, 66 kV, 18 kV).
• Proven experience in the field of protection relays, in particular commissioning and maintenance.
• Proven experience in fault simulations and settings calculations.
• Proven experience in post-mortem fault analysis.
• Experience using a Computerized Maintenance Management System (CMMS).
• Extensive knowledge of power systems, such as sequence components, symmetrical and asymmetrical faults, and power flow analysis.
• Proven experience in the operation and maintenance of a high voltage electrical system, including troubleshooting and repairs.

Qualifications
