what is the difference between delta and y electrical
A wye connection is generally a four-wire system, comprising three line conductors and a neutral conductor, whereas a delta connection is a three-wire system, comprising three line conductors. For a perfectly-balanced load (e.g. a three-phase motor), a wye-connected system can dispense with the neutral conductor.he delta connection provides three line conductors, whereas the star connection provides three line conductors plus a neutral conductor. To obtain a single-phase supply, the load is connected either between any two line conductors, or between a line conductor and a neutral conductor.
