124. In figure «2» of the diagram shown in the illustration, the three-phase step-down power transformer has a turns ratio of four to one. If a three-phase 480 volt supply is connected to terminals «A1-B1- C1», what voltage should develop across terminals «A2-B2-C2»
The transformer's 4:1 turns ratio reduces the 480-volt three-phase supply voltage to 120 volts across the secondary terminals.
