Physics · Three-Phase Systems
In a balanced Star (Y) connection of a three-phase system, which of the following relations is correct for line voltage (VL), phase voltage (VP), line current (IL), and phase current (IP)?
- 1VL = VP and IL = √3IP
- 2√3VL = VP and IL = 3IP
- 3VL = √3VP and IL = IP✓
- 4VL = √3VP and IL = 3IP
Correct answer
VL = √3VP and IL = IP
