Why transmit electricity at high voltage

Password recovery. By Ratna. Now, to be more specific, let us understand it in detail. Why High Voltage Transmission is Required The network of Power Transmission must have effectiveness and safety compliance with cost efficiency. In order to comply with above requirements, Electric power transmission is carried out at high voltage to achieve following: Minimize the Power Losses.

Minimize the cost in power transmission. Let us understand it better with some examples. Power Loss at Volts Transmission As we know, Current through the conductor is: Therefore, Copper Loss in the transmission will be: Power Loss at Volts Transmission Current through the conductor is: Therefore, Copper Loss in the transmission will be: Comparison of Power Loss at v and v Transmission When the Power transmission is carried out at a lower voltage v , the power loss is 40 KW whereas when the Power transmission is carried out at a higher voltage v , the power loss is 0.

Minimize the Cost in Power Transmission The size of conductor in transmission line depends on the current range it has to carry. Ratna Ratna is a B. She is also an active Web Designer. She is an author, editor and core partner at Electricalfundablog.

This increased voltage allows efficient transmission for kilometers or less. There are 3 types of lines: [3]. Power lines lose power to resistance, which is heat generated by moving electric current through a resistor. Above, it was mentioned that high voltage lines reduce this lost power.

As the voltage gets higher, the current must decrease in proportion because the power is remaining constant. However there is a limit, being that at extremely high voltages kV the electricity begins to discharge resulting in high losses.

Transmitting Electricity at High Voltages January 26, Why High Voltage The primary reason that power is transmitted at high voltages is to increase efficiency. High Voltage Market The rapidly growing renewables market has played an especially large role in the high voltage market in recent years.

About Beta Beta Engineering has designed and built numerous high voltage projects across the country. Equipment and machinery should always be kept a safe distance from high voltage lines, appropriate to circumstances. Things such as kites are very dangerous around overhead high voltage lines. If the string from a kite crosses wires, it could complete a circuit transferring the electricity to the person holding the string.

Equipment needs to maintain proper grounding to avoid a shock hazard. If a piece of equipment comes into contact with high voltage lines and is not properly grounded, anyone touching this equipment could get shocked. Maintaining proper grounding reduced the risk of shock.

Despite concerns that living near high voltage power lines might not be safe, scientists have conducted numerous studies since , including a study funded by Congress in , then again by American Physical Society which found no correlation between cancer and power line fields.
