If in transmission line amount of current flow is less then the transmission line will not be heated so that the copper loss will be less and it will reduce the line to line voltage drop. A step-down transformer has fewer turns of wire. Distribution Transformers Are An Electrical Device Which Helps In Converting High Voltage Electricity Into L Electrical Transformers Transformers Manufacturing Transformers are devices used in electrical circuits to change the voltage of electricity flowing in the circuit. Why transformers are used to lower voltages . This makes the connection economical for low voltages transformers. B The main reasons are to keep resistive I squared R losses to a. These are used when voltages need to be lowered for use in homes and factories. A low-voltage transformer taps into a homes high-voltage power supply and produces a safe low-voltage electrical feed. Power is sent long distances at high voltages because less current is required for a given amount...
