What does the Synchronizing Monitor receive input voltages from?

The Synchronizing Monitor receives input voltages from generator or bus tie circuit breakers (CBs) because these components are crucial for managing the synchronization process of multiple generators or sources of power. In the context of electrical systems, the Synchronizing Monitor's primary role is to ensure that generators or other sources are properly synchronized with the electrical grid or with each other before they are connected.

When the generator or bus tie circuit breakers are operational, they provide the necessary voltage readings that the monitor analyzes. This enables the Synchronizing Monitor to compare frequency, phase, and voltage levels, determining if the conditions are right for a safe connection to occur. The other options, while related to power systems, do not specifically serve as the direct input sources for synchronization monitoring in the same way that circuit breakers do.
