What is the function of a Synchroscope on an HV switchboard during generator paralleling?
Direct Answer
Option C: Indicate phase angle alignment and frequency difference between incoming generator and live busbar
The synchroscope is essential for safe generator synchronization. It displays the phase angle difference and frequency relationship between the incoming generator and the live busbar. By ensuring these parameters match, the engineer prevents severe mechanical stress and electrical transients that could occur if the breaker were closed out of phase.
