Hi,
I need some help. i cant find the correct information for this. maybe i am not looking in the right place!!
A three phase system is utilised on a street where a single phase goes to houses with a value of 230V
how would i draw the waveform for the single phase supply
thanks

Simply draw a sine wave with a frequency of 60 Hz. and amplitude (peaks) of the RMS voltage (230V) multiplied by the square root of 2.

The power going into the house is single phase (more precisely split phase).

The connection between the 3-phase and single phase is described here

Since an image is worth 1000 words look here for image of a single phase waveform and a full treatment of the math are given here

This link has a great color picture of a 3-phase system, if you want a single phase picture, just use one of the waves...
