369-HI-R-0-0-0 GE gas turbine control I/O module

Simply put, phase voltage is the voltage between each phase of three-phase AC and ground, while line voltage is the voltage between each two phases of three-phase AC; For example, Low voltage for civil use is generally 380V, the line voltage between each two phases is 380V, and the phase voltage is 380=220V. 220V Single-phase electric power is generally used in households, and low-voltage power electricity for enterprises and institutions is generally 380V Three-phase electric power. Why is the formula Ie=Se/(1.732 * U2e) for the secondary side current of a transformer divided by the capacity Se of a 1.732 three-phase transformer=3 * capacity per phase=3 * phase voltage * phase current.
Three-phase transformer: When connected in a star shape, the phase voltage is 1/√ 3-wire voltage, and the phase current is equal to the line current
When connected in a triangle, phase voltage=line voltage, phase current=1/√ 3-line current
So regardless of the connection method, the capacity of the three-phase transformer Se=√ 3 * line voltage * line current
