A 120V, 60Hz air conditioner is to be operated in a remote area where the voltage drop in the long transmission line results in a utilization voltage of 102V. Determine (a) the required step up voltage ratio for satisfactory performance; (b) the voltage ratio of a standard buck-boost transformer that most closely meets the requirements of the load with the buck-boost transformer installed. (d) Sketch the appropriate connection diagram, and show the NEMA standard terminal markings.
