Physics · Alternators
To connect two alternators in parallel, they must be synchronized to ensure that the voltage across the circuit breaker phases is close to zero at the moment of closing. Which condition is required to achieve this?
- 1The generated voltage must be significantly smaller than the grid voltage
- 2The generated voltage must be significantly larger than the grid voltage
- 3The frequency of the generated voltage must be significantly greater than the grid frequency
- 4The generated voltage must be approximately equal to the grid voltage✓
Correct answer
The generated voltage must be approximately equal to the grid voltage
