A Delta connected load has a phase voltage of 400V. What is the line voltage?
230V
400V
200V
133V
What is the formula for calculating current in a Star configuration?
IL = √3 x IP
IL = √3 ÷ IP
IP = UP
IP = IL
When connecting an ammeter across a Star or Delta configuration, you must connect it in series.
When connecting a voltmeter across a Star or Delta configuration, you must connect it in series.
A star configuration allows you to connect a 230V supply only.
The neutral conductor at the transformer is also called the star point.
