Why 415 volts

The maximum voltage that one can get from any two phases is when one is at the top of its positive cycle i. AHA is correct This article needs to be fixed. Recommended Articles. Please check it.

The phase-phase voltage is V. Although the 'nominal' value has been changed from V to V, no 'actual' change has actually taken place. To convert volts to volts, you use a stepdown transformer of an appropriate rating. Since this is a three phase circuit, you need a three phase transformer, or three one phase transformers.

This can not be done. A single phase supply of volts can be used from a volt three phase wye system but not the other way around. The voltage of volts is a 50 hertz country voltage. The three phase wye connection of this voltage is to ground. This is a three phase four wire system. The three phase voltage is volts. To find the star point voltage divide x 1. You can not use the B phase with a neutral you would have Volts! So, if you have a volt, three phase four wire service grounded service , you can pull one phase off and reference to the neutral for volt service.

Note this may not allow volt service, unless there is also a center tap for each phase. How much current equipments are drawing from three phases combined or individual is called three phase load and how much supply we are getting from source is called three phase supply.

So in three phase supply all RYB phases should be volts ac with neutral individually. If we calculate with phase to phase than it shoulb be volts ac. If they are in different rooms or side by side in the same room, and not connected together mechanically, there should not be a problem. No, the voltage difference is too much. A volt motor falls in the volt range which is separate from the volt range of three phase systems.

Darkwood Mod. It implies that your section is just in your 2 phases, one section is usually yours. I justify it to you in otherwise. In India, we've got a V single-phase system and a V 1. Now if you connect any 2 of the three lines it'll behave rather like the 1-phase offer solely.
