High Voltage Distribution Wiring Diagram. It carries electricity from the transmission system to individual consumers. In a transformer with two high voltage bushings two protective links are used.
Low voltage one line. Wye delta delta wiring diagram 2. Electrical power supply of hvmv2 distribution substations.
A typical primary electrical power distribution system is shown in the figure.

Distribution voltages are typically medium voltage between 24 and 33 kv depending on the size of the area served and the practices of the local. A typical csp transformer schematic diagram is shown in figure 1. Crossed wires without a black dot at resistor an electrical component with a fixed resistance placed in a circuit to reduce voltage to a specific value.
