What is an industrial semaphore?
An industrial semaphore, or position indicator, is a visual device that communicates the state of electrical and mechanical equipment to an operator. Installed on protection and control panels, it provides a clear indication of open, closed, intermediate or fault conditions.
How does a semaphore display equipment status?
Status commands are received from circuit breakers, disconnectors or control circuits. According to the configured logic, the semaphore displays the corresponding illuminated symbol. High visibility, rapid recognition from a distance and dependable operation in industrial environments are important selection criteria.
Applications in power systems
Semaphores are widely used in transmission and sub-transmission substations, power-plant control panels, dispatching centres and industrial monitoring systems. They enable operators to verify equipment states without ambiguity and react more effectively to a state change or fault.
