  • Grid of the future
    For most other customers, the primary voltage is stepped down with distribution transformers to the “secondary” or low-voltage level, 480Y/ 277 volts or 208Y/ 120 volts for the three-phase voltages serving most commercial buildings and 240/120 volts for single-phase…
  • Lineman's and Cableman's Handbook, Twelfth Edition > Electric System
    The distribution transformers reduce the voltage to utilization level, usually 120/240 volts single-phase for residential service and 208Y/ 120 or 480Y/ 277 volts three-phase for commercial or industrial service.
  • Lineman's and Cableman's Handbook, Twelfth Edition > Distribution Transformers
    Figure 15.16 illustrates the proper connections for three single-phase distribution transformers connected to a three-phase four-wire grounded neutral wye primary-voltage system to obtain 208Y/ 120 - or 480Y/ 277 - volt secondary service.
