/ Content
Theory:
• The 225 and HV 1983 protection plans and the 400kV plan,
• The LV functions of line units, couplers and transformers,
• Communication links between equipment on substations,
• Functional links between equipment in these units,
• Inter-unit circuits in substations,
• Functional links from the substations to the busbar protections.
Practical exercises :
• Electrical safety,
• System safety (isolation of equipment, of a unit, specific LV features),
• Preparing the procedure for carrying out the operation,
• Understanding the functions of the units,
• Analysis of functional interactions (links between equipment and units, initialisation of PLCs, differential protection, remote reactions, differential busbar protection, disconnection, substation PLCs, inter-unit, etc.),
• Drawing up a test methodology,
• The test conditions,
• The role and responsibilities of the Works, Test or Intervention Manager will also be detailed.
/ Objective
• Identify the role and responsibilities of an ASI Works, Test or Intervention Manager,
• Apply a methodology to explain the functions of CC units,
• Prepare, carry out, evaluate and report on an LV operation.
