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

The condition where the current is delayed in time with respect to the voltage in an ac circuit (for example, an inductive load).

Information about the chosen lamp and its lumen depreciation and mortality are available from lamp manufacturers’ literature. Rated average life should be determined for the specific hours per start; it should be known when burnouts occur in the lamp lif

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.

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