Definitions:

Phase Current

The amount of current flowing in the phase of a three-phase load or power supply.

Line Current

The current flow in the line supplying a three-phase load.

Apparent Power

A measure of the total power in an AC circuit, expressed in volt-amperes (VA), that combines both real power (measured in watts) and reactive power (measured in volt-amperes reactive, or VARs).

Three-Phase Circuit

An electrical circuit design that uses three alternating currents, each of which reaches its peak value at one third of a cycle from the other, to efficiently supply power.
