It must be usable. There are two star connection methods: three-phase three-wire system and three-phase four-wire system, that is, the center line is not. released! If both phases are used directly, the line voltage is 380 V. The voltage between one of the three phases and the center line is 220 V. If you output one phase directly, it will be 220 V!
Generator Usage Problems
Introduction The generator must be usable. There are two star connection methods: three-phase three-wire system and three-phase four-wire system. Yours is a three-phase, three-wire system, meaning the center line is not out. ! It is a direct two-phase phase
