Reference Answer
### (a) Definition of Synchronizing an Alternator
Synchronizing, also known as paralleling, is the process of connecting an AC alternator (the 'incoming' machine) to a live electrical system, typically the main switchboard bus-bars, which may already be energized by other running alternators. The primary objective is to ensure a smooth, disturbance-free connection to enable load sharing or to increase the available power capacity of the ship's electrical plant.
Key objectives and concepts include:
* **Load Sharing:** To connect an additional generator to meet an increasing electrical load demand on the vessel.
