HMF-MAK Training Secondary (MCP)

Objectives
• Understand the purpose and structure of a Protection & Control (MCP) diagram.
• Identify the key components and symbols used in P&C block diagrams.
• Learn to interpret the signal flow between the primary plant, IEDs, and control systems.

Key Topics
• Overview of the “Métier de Contrôle-Protection” (MCP) concept.
• Functional breakdown of protection functions (e.g., 50/51, 87T, 64REF) on the diagram.
• Control functions (circuit breaker control, isolator switching) and interlocks.
• Interface with CTs, VTs, and circuit breaker auxiliary contacts.
• Communication paths (Station Bus, Process Bus) versus hard-wired signals.
