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
You could replace the conductor, but at the present time that is prohibitively expensive. The most economical conductor is aluminum cable. Losses can be reduced with effective insulators, of course, which is also already being done.
Transformers modify the wave forms sent down transmission lines to match the spacing between towers and the way the lines sag. This helps reduce transmission loss.
There are likely many other tricks.
Broadly:
1. Increase the conductor size, assuming that you cannot change the system voltage, the reduction is linear, eg 16sqmm to 35sqmm will halve the losses.
2. Increase system voltage, eg, a move from 11kV to 33kV will provide approx a 9 fold decrease in transmission losses with the same conductor size.
3. Cool the conductors, most conductors begin to de-rate above 20 C.
4. Use 'power factor' correction to decrease the 'reactive power' loss... see KVA/KW discussion.
5. Provide capacitive loads along 'long transmission' lines, ie, over 50km, to avoid resonance effects and control over voltage/current.
Transmission losses are less in HV or EHV transmission lines. Higher the voltage lower the losses.
High voltage DC transmission is another way to have less transmission losses.
Using larger amounts of copper will decrease copper loss (use bigger wire than necessary).
In general, it is cheaper to transport power long distances at higher voltage levels. Do not take this as a rule as always being cheaper, otherwise you would have a 500kV line into your home.The resistance in the power company's lines is not zero. There is always going to be some loss in quality whenever energy is transferred. Thus, when electricity is transferred, the power dissipated by the lines, even lines with a REALLY small resistance, like 1 micro-ohm per mile, adds up when one counts the millions of linear miles across which electricity is transmitted. The power dissipated can be calculated with the formula, P= VI, which through Ohm's law becomes P = (I^2) x R, where P = Power dissipated, V = voltage, I= current, and R= resistance. Thus, using the same resistance wire and the same power source, a higher voltage will have a lower current and less power will be dissipated as heat.It is not cheaper to transport electric power at high voltages. What we are looking for is the smallest amount of loss during that transfer. The higher the voltage the lower the percentage of loss for a given diameter of wire. The costs associated with stations to step up and down power and to maintain these stations is very high. What the goal is here though is making as much power as possible reach our final destination. This is also why we use aluminum wire for transfer rather then copper. It is all about reduced loss, cost is a secondary concern.
Tramsission losses are due to the inherent resistivity of the transmission medium (the wire in overhead and underground transmission lines). All substances have a specific resistance. As current is pushed through that substance, a voltage drop across that resistance will result that follows ohm's law: V = I * R. Power is equivalent to P = V * I, thus P = I^2 * R.
because the voltage decreases through the wind, and doesnt allow it to get through to the consumer +++ Nothing to do with the wind - apart from physical damage of course! The losses in the line are due to low but definite electrical resistance within the cable, and inductive losses within the transformers. So the main transmission lines work at very high voltages to reduce the current hence resistance loss, and the voltage is transformed down to industrial and domestic levels close to users.
Power lines run at high voltages to overcome line loss.
Using larger amounts of copper will decrease copper loss (use bigger wire than necessary).
there are some distortion in transmission line : copper loss,dielectric loss,skin effect
To reduce heat loss by thermal radiation.
The term, 'power loss', describes the rate of energy losses caused by the load current in the transmission lines
The darker the color is, the less heat radiation occurs.
Reactance certainly causes loss in a transmission system, but I^2R or resistance losses are greater.
There is a silvering in the vacuum flask in order to reduce the loss of heat through the means of radiation.
A vacuum between two glass sheets will greatly reduce heat loss through convection, and also through conduction. The fact that the glass is coated (to convert it to a mirror) also reduces the loss by radiation.
Using vacuum as an insulator avoids heat loss by conduction. Heat transfer is minimised by reflective silver surfaces that are applied to the flask. This prevents thermal radiation from entering and escaping the flask.
for instance, Heat loss through the roof of the house can be reduced by laying loft insulation. This works in a similar way to cavity wall insulation.
Insulation reduces heat loss by replacing air space with a less conductive material (insulation). Therefore the answer is conduction.
Mutual fund do not reduce the risk of loss.
