Three Phase Transformer - 500 Va To 200 Kva | Delta And Wye/star Configurations For Enhanced Voltage Management

Three phase transformers are used throughout industry to change values of three phase voltage and current. Since three phase power is the most common way in which power is produced, transmitted,three-phase transformers are used to step voltages up or down. A three-phase transformer is made of three sets of primary and secondary windings, each set wound around one leg of aniron core assembly. Essentially it looks like three single-phase transformers sharing a joined core. These transformer range is available from 500 VA TO 200 KVA

WYE/Star Connetion
In a wye system the voltage between any two wires will always give the same amount of voltage on a three phase system. However, the voltage between any one of the phase conductors (X1, X2, X3) and the neutral (X0) will be less than the power conductors. For example, if the voltage between the power conductors of any two phases of a three wire system is 208v, then the voltage from any phase conductor to ground will be 120v. This is due to the square root of three phase power. In a wye system, the voltage between any two power conductors will always be 1.732 (which is the square root of 3) times the voltage between the neutral and any one of the power phase conductors. The phase-to-ground voltage can be found by dividing the phase-to-phase voltage by 1.732
