TAB technicians routinely measure electrical voltage and amperage on HVAC equipment as part of our regular testing activities. However they should also understand the source of that electrical energy, how it is distributed throughout the facilities, and how to use the standard data collected to estimate the work performed by the motors in the equipment. This webinar will address a basic description of electrical power distribution in commercial facilities, how an induction motor operates, data that should be collected or measured, and how this data can be used to estimate brake horsepower for the purposes of comparing electrical measurements with air and water system performance measurements (i.e. flow and pressures).
