Apr 12, 2013 · Building distribution transformers in turn step the distribution voltage down to a utilization voltage of 120/208 volts, three phase 4 wire and/or 480/277 volts three phase four wire. Brown University facilities located in the downtown area (Jewelry District) are typically directly served by National Grid, the local utility company.

In most cases, the control transformer is used to reduce the main or line voltage of 240 VAC or 480 VAC to a control voltage of 120 VAC. Notice that the primary windings are crossed. This is done so that metal links can be used to connect the primaries for either 240 or 480 VAC operation, as shown in Figure 1.10.

Application 3PH Service - PPL Electric
PPL EU’s service wires, transformers, meters and other equipment will be installed to meet the load requirements as provided to us on the submitted application and will have a limited excess capacity. For a typical secondary service it takes approximately 6 months to provide service and approximately 8 months for 12 kV Primary services.
