I have been having good luck in helping my commercial and industrial customers reduce energy consumption by conducting portable energy audits to track down energy draining devices. As a first step I connect the clamps and leads of my Fluke 434 power quality analyzer and select energy from the menu to measure measure the average watts of the equipment that I am suspicious of. Then I convert the average watts reading to watt-hours by multiplying by the amount of time over which the average was measured. This technique for measuring real power consumption (kWh) can also be applied to apparent power (kVA) and reactive power (kVAR) by setting the power meter to measure the running average kVA and kVAR and multiplying by the recording time.
