Abstract
A distribution transformer for use in a providing electrical power to sites, includes a ferromagnetic core; a primary winding configured to be connected to a source grid at source grid voltage; and a secondary winding configured to be coupled to service cables to supply electrical energy to at least one of the sites at a first line voltage and at least another of the sites at a second line voltage, wherein the second line voltage is higher than the first line voltage.
Claims19
A distribution transformer for use in a providing electrical power to sites, the distribution transformer comprising:
- a ferromagnetic core;
- a primary winding configured to be connected to a source grid at source grid voltage;
- a secondary winding configured to be coupled to service cables to supply electrical energy to at least one of the sites at a first line voltage and at least another of the sites at a second line voltage, wherein the second line voltage is higher than the first line voltage.
A system for connecting a source grid to residential sites including a first residential site and second residential site, the system comprising:
- a distribution transformer for use in a providing electrical power, the distribution transformer having at least one primary voltage connection to the source grid at source grid voltage, and secondary voltage connections providing electrical energy to the first residential site and to the second residential site;
- a first set of service cables connecting the secondary voltage connections to a first residential site at residential line voltages for residential service at the first residential site;
- a second set of service cables connecting the secondary voltage connections to the second residential site, at a higher line voltage than the residential line voltages for stepping down at the residential site.
A method of delivering electrical energy from a source grid to residential sites including a first residential site and second residential site, the method comprising:
- utilizing a distribution transformer, stepping down from a grid voltage to line voltages of 120V along a first set of service cables and providing 120V/240V service to the first residential site;
- utilizing the distribution transformer, stepping down from the grid voltage to 480V along a second set of service cables to provide 480V and 100 A for stepping down at the second residential site.
