Star and delta phase voltages

[Lee Gold]

I came across a question today in my paper asking me to draw out star connection and a delta connection and draw out phase voltages on star from phase to phase and write in the voltage and I don't understand it at all can somebody help please. Star carrying 240/400v delta 400v Sorry I'm not very good at explaining things to cut a long story short how do I know what the voltages are from phase to phases

Three-phase Y and Delta Configurations : Polyphase AC Circuits - Electronics Textbook does this help?

to simplify it, in delta your phase voltage and line voltage are the same. in star, your phase voltage is LINE VOLTS/ √3

Cheers mate I will read it now
