What equipment is each SG section equipped with?

Each SG section is equipped with a synchroscope and synchronizing lights because these tools are essential for the synchronization of generators to the power grid or to other generators. The synchroscope provides real-time information on the phase angle between the generator and the grid frequency, allowing operators to determine when to connect the generator to the grid to ensure that they are in phase. Synchronizing lights act as visual indicators that show whether the generator is ready to be synchronized with the grid. This is crucial for maintaining stability and reliability in the electrical system, preventing operational issues and potential damage to equipment.

The other options, while important in their contexts, do not specifically pertain to the primary equipment used for synchronization tasks within an SG section. Power relays and circuit breakers, voltage regulators, and transformers and inverters serve different functions within the system and do not directly relate to the synchronization process as effectively as synchroscopes and synchronizing lights do.
