Wye/wye primary neutral |
With balanced load still has 3rd harmonic. 60hz × 3 =180hz. Must be identical trans without PN |
|
Wye/wye voltage |
Primary line ex. 208= primary phase 208÷R3 Secondary phase ex 120 Secondary line=120 × R3 |
|
Wye/wye current |
Primary phase current=transformer VA ÷ primary phase V Same for secondary |
