The maximum power flow in a transmission line is determined by its thermal limits, voltage levels, and the line's impedance. It can be calculated using the formula ( P_{max} = \frac{V^2}{Z} ) for a given voltage ( V ) and impedance ( Z ), or through the use of power flow equations in AC systems. Factors such as line capacity, temperature, and safety regulations also play a crucial role in determining the maximum power transfer capability. Additionally, reactive power considerations and the phase angle between sending and receiving ends impact the overall power flow.

What is the maximum transmission speed for fiber optic?
The maximum transmission speed for fiber optic is about 186000 miles per second. Wires are a bit slower because of transmission line effects
Calculations on input impedance of a transmission lines?
I assume you are wanting to know about balancing networks to a transmission line? If this is the case, you really need to get a book on networks and filters. The physical makup of the transmission line will impact this calculation. The basic idea is you want to match the impedance at the input (looking out of the transmission line) to the same impedance as the transmission line (say 50 or 75 ohms for typical coax), and the output impedance (looking out of the transmission line) to the same as well. This will result in maximum power transfer, minimum power reflection. If you want to know how to make a balancing filter to a transmission line, then you need to design the filter according to your requirements - chebyshev, minimum ripple, wide band, narrow band, etc; You may need to use transformers to isolate the transmission line from your power circuitry, and use this as a matching network. You could also use transistors to accomplish similar things (less isolation, though), depending on what you're trying to do.

What is the amount of power loss on a transmission line that is transmitting 10 MW at 500 kV with 1000 ohms?
Line current = 10MW / 500kV = 20A Assuming the 1000 ohms is the resistance of the entire transmission line, end to end. Power loss = line current ^ 2 * line resistance = 20A ^ 2 * 1000 ohms = 400 KW
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..
How do you transmit ac power flow in HVDC transmission line?
You don't! That's the whole point of a d.c. transmission line.
What is transmission line amps rating?
The amp rating of a transmission line is the maximum current that can safely flow through the line without causing damage. This rating is based on the material, size, and design of the transmission line to ensure it can handle the electrical load without overheating or overloading. It is important to adhere to this rating to maintain the safety and efficiency of the transmission line.
In electrical power transmission the line must have reactance to flow of the power without the reactance the power cannot flow please answer for this if required give mathematical expression thanx?
Electrical transmission lines do have reactance, but it is not necessary for power to flow. In fact, the smaller the reactance, the higher the efficiency of the transmission system. Reactive power is not delivered to the load, it does no useful work, it just costs money to generate and causes heating of the conductors.
What makes a power line work?
A power line works by electrons flowing through from power line to power line but if something interferes with the power lines the flow of electrons will not work. (flow)

How much the maximum power delivered through 400kV 2x520 sqmm 200 kM long line?
To calculate the maximum power delivered through a 400 kV transmission line, we use the formula ( P = V \times I ), where ( P ) is power, ( V ) is voltage, and ( I ) is current. The maximum current that can be carried by the 2x520 sqmm conductors depends on their thermal limits, which can vary based on ambient temperature and installation conditions. Assuming a maximum current of around 800 A for this conductor type, the maximum power can be estimated as ( P = 400,000 , V \times 800 , A = 320,000,000 , W ) or 320 MW. However, this is a simplified calculation and actual power delivery would depend on various factors, including losses and line characteristics.
