Definitions:

Delta

In electrical engineering, it often refers to a triangular connection in a three-phase system where the end of one winding is connected to the start of the next.

Three-Phase Power Systems

Electrical power systems that use three alternating currents or phases, each phase being out of phase with the other by one-third of a complete cycle, widely used for power transmission and large electric motors.

Delivered Power

The amount of electrical power supplied to a load or system by its source.

Cycle

In an alternating current (AC) circuit, one complete waveform, including a positive and a negative swing, usually measured in hertz (Hz).
