From the single-line diagram, at the point of interconnection, either a step-up or step-down transformer is installed as per the voltage level.
Rotary converters were indeed used in railway electrification systems. A rotary converter is a type of electrical machine that can convert alternating current (AC) to direct current (DC) or vice versa. In the context of railway electrification, these converters were often used to convert AC power from the grid into DC power for the operation of electric trains.
In electrical systems, domestic consumers typically connect to the distribution network rather than the main transmission network. The main transmission network, also known as the high-voltage transmission grid, is responsible for transporting bulk electricity over long distances from power plants to various regions. The distribution network, on the other hand, operates at lower voltages and is designed to deliver electricity directly to homes, businesses, and other end-users.
Hence, the correct answer is option 4.
