A substation control panel is the centralized interface for monitoring, controlling, and protecting electrical equipment and circuits within the substation.

Panel Components

• •HMI displays: Touch screens or graphical displays for system visualization
• •Control switches: For manual operation of circuit breakers and isolators
• •Indicator lamps: Status indication for equipment states
• •Meters: Voltage, current, power, and energy measurements
• •Relays: Protection and automation relays
• •Annunciators: Alarm indication and acknowledgment

Panel Types

• •Local control panels (LCP): Equipment-specific control
• •Marshalling panels: Signal consolidation and distribution
• •Relay panels: Protection relay housing
