True or False: A three-phase symmetrical power supply is connected in a three-phase four-wire system in order to provide two different voltages to the load. In low-voltage distribution systems, the standard voltage values are 380 V for the line voltage and 220 V for the phase voltage. （）
Correct,√~~~~~~~~~~
A three-phase symmetrical power supply is connected in a three-phase four-wire system in order to provide two different voltages to the load. In low-voltage distribution systems, the standard voltage specifies a line voltage of 380V and a phase voltage of 220V. (Yes)
