Three phase four wire system: phase voltage: phase line voltage between neutral and; Line voltage, phase ac electric motor and phase line voltage between two wire. Every relative phase voltage is the three-phase alternating current voltage and line voltage is three-phase alternating current (ac) and every two voltage; Like civil low-voltage electrical is 380 v, and every electric motor price two line voltage is 380 v, 3 phase voltage is present 380) = 220 v, people are generally single-phase 220 v electric, enterprises and use the low voltage power generally is 380 v three-phase electricity. Phase voltage: Ren Yixiang line and zero line in the Three phase motor three phase line voltage. Line of line voltage, three phase line to line voltage. Relationship: U = U line / 1.732. Two phase current: phase line and zero line load current. Line current, three-phase load between line and line current. Relationship: I = P/U/power factor, phase I line = P / 1.732 / U/power factor.
