What is the purpose of the Synchroscope and Synchronizing Lights?

The purpose of the Synchroscope and Synchronizing Lights is to ensure that two or more generators can be connected in parallel without any issues. When generators operate in parallel, they must be synchronized in terms of voltage, frequency, and phase. The Synchroscope provides a visual indication of the phase relationship between the incoming generator and the ones already connected to the bus. When the generators are properly synchronized, the synchronizing lights will indicate this by showing that the generators are in phase.

This functionality is crucial when the switchboard is in local control because it allows the operator to carefully manage the synchronization process. If the generators are not synchronized correctly, it can lead to equipment damage or system instability upon connection. Thus, utilizing the Synchroscope and Synchronizing Lights enables safe and efficient operation of generators in parallel configurations.
