Best Answer

To calculate the power consumption of an electrical or electronic device you have to multiply the voltage applied to the device times the current consumed. This is a little trickier than it would first appear; the voltage applied is usually 120 volts(117 to 125 but who's counting?) the current consumed is a bit more complicated. To measure this requires an ammeter ( an AC ammeter) and a little time. The current consumption will not be constant, so it must be averaged over time. The longer your time measurement the more accurate your power measurement will be.

House Load of a Power Plant is also known as Auxiliary Power Consumption or Units Used on Works.It is the electrical power needed to drive the pumps and fans that support the operation of the power plant.Typically the power plant metering is set up to measure the electricity produced by the generator at the terminals. A seperate meter will measure the electricity used by the auxiliaries, at the unit transformer.Auxiliary Power Consumption is often expressed as a percentage of Units Generated, so:Aux Power = ( Units Used on Works / Units Generated ) x 100 %% MWh MWhTypical Auxiliary Power Consumption depends on the type of plant:Plant Type%Coal-fired Thermal6.5 - 8.0Open Cycle Gas Turbine2.5 - 3.5Combined Cycle Gas Turbine1.0 - 1.5
