We explain how

  • Wye configuration provides 120/208V or 277V/480V

  • How delta provides just 480V

  • How high leg delta provides 240V/120V/208V

  • How open delta provides 240V/120V/208V and how the capacity is reduced for the rated kVA as well as compared to full delta bank kVA

Worked examples for:

  • How to calculate wye line to line voltage using trigonometry,

  • How to calculate the line wye line voltage from the sine waves between phases,

  • How to calculate the line current for a delta configuration using trigonometry

  • How to calculate the high leg voltage using trigonometry

Formulas provided with worked examples for:

  • Wye - phase voltage, line voltage, phase current and line current

  • Delta - phase voltage, line voltage, phase current and line current.

  • High leg delta - phase voltage, line voltage, high leg voltage, low leg voltage, phase current, line current,

  • Open delta - phase voltage, line voltage, high leg voltage, low leg voltage, phase current, line current
