What else can I help you with?
To reduce power losses in transmission lines the voltage is made?
Much higher.
What is the purpose of having a low impedance for transmission lines?
in order to reduce the transmission line losses we need low impedance...Low impedance also improves power transfer capacity of the line..
Why do you step up voltage from 11kV to 400kV during transmission?
Stepping up voltage from 11kV to 400kV during transmission is primarily done to reduce energy losses over long distances. Higher voltages allow for lower current flow for the same power transfer, which minimizes resistive losses (I²R losses) in the transmission lines. Additionally, higher voltage transmission is more efficient and enables the use of thinner, lighter conductors, reducing infrastructure costs. This process is typically achieved using transformers at substations.
How do you reduce radiation loss in transmission lines?
Transmission loss reduce by using 1) higher diameter conductor (R = q l / a) or specially maded low loss conductors 2) using energy efficient equipment such as low loss transformer 3) twisted conductors instead of solid 4) proper monitoring and control of transmission eqipment 5) use of high temperature super conductors ....etc
What are the advantages of 750Kv high voltage?
A high voltage like 750kV is used in transmission lines because this reduces the current in the wires for a given amount of power. A reduced current will reduce the power lost in transmission (I^2R).CommentFar more importantly than reducing line losses, it reduces the voltage drop along the line which would, otherwise, be enormous!
To reduce power losses in transmission lines the voltage is made?
Much higher.
Why there are no losses in DC transmission?
There are losses in d.c. transmission lines, due to their resistance. But there are no reactive losses. So, d.c. transmission lines have less losses in comparison to an equivalent a.c. transmission line.
What is the purpose of having a low impedance for transmission lines?
in order to reduce the transmission line losses we need low impedance...Low impedance also improves power transfer capacity of the line..
What is a set of standards for digital transmission of data over standard copper telephone lines?
The set of standards for digital transmission of data over standard copper telephone lines is ISDN
Why copper is used in electrical transmission line?
Copper is a good conductor and is fairly strong. It generally is not used in power transmission lines due to cost - generally aluminimum is used.
What is signal distortion in transmission lines?
there are some distortion in transmission line : copper loss,dielectric loss,skin effect
What are the advantages of using copper compared to aluminium for transmission lines?
Copper is a better conductor than aluminum. Two wires with the same cross-sectional area, or any two constructs with the same physical shape and size, one fabricated from aluminum and the other from copper, the one made of aluminum always has higher ohmic resistance.

What does power loss in electrical transmission mean?
The term, 'power loss', describes the rate of energy losses caused by the load current in the transmission lines
It transmits electricity like copper?
Aluminum is a good conductor of electricity similar to copper. It is often used in power transmission lines due to its conductivity and lower cost compared to copper.

Is reactance major responsible for power loss in power transmission lines?
Reactance certainly causes loss in a transmission system, but I^2R or resistance losses are greater.
