Secondary P&C Interface Drawings

We have extensive experience in interfacing and coordinating a wide range of engineering drawings and documentation associated with secondary protection and control systems for electrical substations and power plants. Our work covers both greenfield (new) installations and brownfield (replacement or upgrade) projects.

​

The scope of our expertise includes the integration and interpretation of the following drawing types:

• Wiring Diagrams (AC & DC): Detailed point-to-point connections for control and protection circuits.

• Termination Diagrams: Mapping of cable cores to terminal blocks and devices.

• Cable Schedules: Documentation of cable types, routes, terminations, and quantities.

• Cable Block Diagrams: High-level overviews of cable connections between equipment, panels, and buildings.

• SCADA and RTU Interface Diagrams: Communication and I/O mapping for remote monitoring and control systems.

• Panel Layouts and GA Drawings: Layout of protection and control equipment within panels.

​

Our role often involves ensuring the consistency and accuracy of these drawings across multiple disciplines and systems, identifying potential conflicts, and supporting site implementation with clearly documented and coordinated designs.
