Why are the two lamps of a synchronizing switch connected in series?
Tuesday, March 10th, 2009Mike asked:
When an incoming alternator needs to be synchronized with the bus-bar, we use a synchronizing switch (let it be 3 dark lamp method). when the lamps go dark we close the switch (provided the voltage and phase are matched and also the rate of flickering is minimum). But why are the two lamps in each phase connected in series? can’t it be one? or in parallel?
Has it got something to do with inductance n voltage division??
