A symbol used to express inductance. The unit of measure is a “Henry”.

KVAR is the measure of additional reactive current flow which occurs when the voltage and current flow are not perfectly in phase.

1) Apparent Power expressed in Thousand Volt-Amps. 2) Kilovolt Ampere rating designates the output which a transformer can deliver at rated voltage and frequency without exceeding a specified temperature rise.

Result of when a sinusoidal e.m.f. is applied to the secondary terminals of a current transformer is increased by 10% causes the exciting current to increase by 50%.

The use of one thousand watts for one hour.
