How can you calculate the capacity in megawatts of a 400 kv power line?

You have to know the current carring capacity of the line and the power factor to make the calculation. Watts = Amps x Volts x p.f
If p.f is unity, then watt = Amps x Volts

How many amps does a 18000 watt generator provide at 120 volt 3 phase service?
The equation for power in a three-phase system is given by the following equation:P = 1.732 x line voltage x line current x power factorSo, to calculate the line current, we can manipulate this equation, as follows:line current = power / (1.732 x line voltage x power factor)As you make no mention of power factor, we shall assume the power factor is 1, and we also need to assume the 230 V you quote is a line voltage, so we can calculate the value of current as follows:line current = 18 000 / (1.732 x 120 x 1) = 86.6 A
What is the meaning of the term load shedding?
The term load shedding means the process of terminating or disconnecting the electrical currents on a line when the line is overloaded. Load Shedding is the deliberate shutdown of electric power in a part or parts of a power-distribution system, generally to prevent the failure of the entire system when the demand strains the capacity of the system
To find the acceleration of an object moving in a straight line you must calculate the charge in distance during unit of time?
You calculate the charge in velocity, not in distance.
How do you calculate current and voltage passing through light globes?
You can't "calculate" both. If you know the wattage & the line voltage then I = P / E and vice-versa.
How do you find out the power rating of your power supply?
In America it should be 60hz. But you can hook up a power meter to the line and find out the real frequency and voltage of the common household or office power line. You may be surprised at the number of spikes and drops in voltage and frequency in a household line. A good UPS can some times tell you as well.

How do you Start three phase motors?
Three Phase Induction Motor is self starting motor so you can start it by conneting to power lines directly if the power line capacity is sufficient.
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 start three phase induction motor?
Three Phase Induction Motor is self starting motor so you can start it by conneting to power lines directly if the power line capacity is sufficient.
How much power can a transmission line carry example how much power can a 69kv line carry compared to a 390kv line what is the formula for power capacity of a hvac line?
For a line of given cross section and material, the power capacity will depend on the current carried, since resistance heating is proportional to (current)2 . For a given power, current is inversely proportional to voltage. Thus raising the voltage from 69 to 390 kv would reduce the current by a factor 69/390 = 0.177 , for the same power transmission, and reduce the heating losses by 0.1772 = 0.031. So you can see why high voltage for long distance lines is essential. Obviously the limiting current on a power line has to be set by economic and practical considerations, but if this is predetermined and set, the limiting power will be that which produces that limiting current, and power = voltage x current. The actual limiting curent will depend on the line cross section, material, and length. The power that a line of a certain voltage can carry is calculated by using the following formula: (2.55×(KV)2 /1000) MW.
A T1 line represents more line capacity than an E1 line.?
false
How you can calculate current of a load when you have three phase supply with 237 volts328.4 KW Power and 0.99 cosfi?
The general equation for power in a BALANCED three-phase load is as follows:P = EL IL x power factor...where EL and IL are the line voltage and line current, respectively.So all you have to do is to manipulate the equation to make the line current the subject, and insert your figures.
Which has greater line capacity T1 or E1?
The E1 has a greater line capacity. E1 is the European standard and runs at 2.084 Mbps. The American T-1 standard runs at a capacity of 1.544 Mbps.
A transmission line has 30 megawatts and 40 megavars what is the megavolt amps load on the line?
By definition, MVA is equivalent to the vector sum of MW and MVAR: MVA^2 = MW^2 + MVAR^2 = 2500 MVA = 50
How do you calculate 3 phase power factor?
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.
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)
