Design Principles for Pole-Mounted Distribution Transformers(1) Location and Layout PrinciplesPole-mounted transformer platforms should be located near the load center or close to critical loads, following the principle of “small capacity, multiple locations” to facilitate equipment replacement and maintenance. For residential power supply, three-phase transformers may be installed nearby based on current demand and future growth projections.(2) Capacity Selection for Three-Phase Pole-Mounted Tr

1. OverviewDue to global warming, reducing greenhouse gas emissions is a critical issue. A significant portion of losses in power transmission systems comes from power transformers. To reduce greenhouse gas emissions in power systems, more efficient transformers must be installed. However, more efficient transformers often require more manufacturing materials. To determine the optimal loss ratio and manufacturing price of transformers, the Total Cost of Ownership (TCO) method is the industry sta

1. Specific Design1.1 Design ConceptState Grid Corporation of China actively promotes grid energy conservation and low-carbon development to achieve national carbon peak (2030) and neutrality (2060) goals. Environmentally friendly gas-insulated ring main units represent this trend. A new 12kV integrated environmentally friendly gas-insulated ring main unit was designed combining vacuum interrupter technology with three-position disconnectors and vacuum circuit breakers. The design utilized Solid
