2010年5月17日 · Three-phase electric power requires less conductor mass for the same voltage and overall amount of power, compared with a two-phase four-wire circuit of the same carrying …

2024年10月5日 · Only came across three wire two phase once. We had 2,300 volt two phase three wire feed a 3 story building where they had boning rooms for cutting expensive pieces of …

2013年7月29日 · I am wondering if what the OP describes as "two phase" is just our single phase. Single phase = Two wires 120 volt only Two phase = Three wires 208/240 between two hots, …

2019年11月14日 · When you draw the vector diagram, the third line is the same length, indicating the voltage of the open phase is the same as the other two. With two phase, the phase angle …

2017年3月19日 · If we take the range of magnitude of phase-to-neutral voltage to be between 230 V and 240 V, the range of phase-to-phase voltage would be 398 V to 415 V. Usually, we …

2009年6月29日 · Setting semantics aside ("neutral" vs "grounded conductor"), to date, I don't recall ever seeing two phase conductors (of the same phase) share a common neutral, even if …

2008年11月30日 · I ran into two-phase several years ago. An old time motor winder told me that two-phase is actually two different circuits, like two coils. One set of leads will have a different …

2010年2月15日 · Each 120-volt line runs 180 degrees out of phase with the other. With the neutral as common to both, if a multimeter was used to measure across the neutral line and any one …

2019年7月3日 · Your 230VAC 3 phase motor is actually using 208V, 3 phase but most motors will happily run at a wide range of voltages. Your 230VAC single phase brake will likely run at …

2009年6月25日 · All single phase is derived from one leg and a neutral, or two legs, of a three phase network. Even if the three phase sine waves are 120 degrees apart, the current in just …
