Can transmission circuit breakers operate due to low voltage conditions?

Transmission circuit breakers are designed to protect electrical circuits by interrupting the flow of current during abnormal conditions, which can include low voltage situations. When voltage levels drop below predefined thresholds, this can indicate a possible issue in the electrical system, such as an overload or other fault conditions.

In specific scenarios, low voltage conditions can prompt circuit breakers to operate, assuming they are designed with protective features that monitor such parameters. This function is critical in preventing damage to electrical equipment and ensuring the stability of the power system. For instance, if a circuit breaker detects a sustained low voltage condition that could lead to equipment damage or operational inefficiencies, it may trip to protect the overall system.

The other options imply restrictions on the circuit breaker's operation that do not align with its protective purpose. Circuit breakers have the capacity to act not just during faults but also under various anomalies including low voltage, making the assertion that they can operate due to low voltage conditions accurate.
