How is a breaker trip typically indicated?

The indication of a breaker trip is typically done through local indicators and Electrical Power Management Systems (EPMS). Local indicators provide immediate visual feedback on the status of the circuit breaker, such as lights or displays that show whether the breaker is in the "tripped" or "closed" position. EPMS can also integrate data from various components of the power system to present a comprehensive view of breaker status, including any trips that occur. This makes it easier for operators to monitor and manage the electrical system effectively.

Considering the other options, remote control signals may facilitate operation of circuit breakers but are not usually the means of indicating a trip status. Visible smoke can indicate various electrical issues but is not a reliable or standard method of indicating a tripped breaker. Audible alarms are useful for alerting personnel to issues, but they do not provide the precise and immediate feedback that local indicators and EPMS do.
