Definitions:

Three-Phase Connection

A method of electrical power distribution that uses three alternating currents of the same frequency and amplitude, which are offset in time to provide a more constant and efficient power supply.

Inductive Loads

Electrical components or devices, such as motors or transformers, that primarily use magnetic fields to function, causing a phase shift between the voltage and current.

Delta

A method of electrical connection in which each side of a load is connected to a vertex of a triangle-like configuration, with power supplied at each vertex.

Wye

An electrical configuration where three components are connected at a single common point, forming a Y shape.
