WebAnswer (1 of 9): What happens to frequency if the load on the generator decreases? As the load falls off, the frequency will rise if the governor driving the prime mover has been set up for “droop”. Droop is an essential characteristic for any machine that has to work in parallel with other alte... Synchronous generator is also known as: 1. Degenerator 2. Alternator 3. Decoupler 4.
