If the output voltage of a power plant is 3300v, the electric power delivered is 3300kW, the resistance of the transmission line is 2 ohm, what are the heating power and loss rate Please help me with the next question
Because I = P / u
=3300000/3300
=1000A
The current on the wire is 1000A
And then according to Joule's law
P=r*I^2
=2*10^6W
=2000kW
Therefore, the heating power is 2000 kW
Then the loss rate is calculated
That's 2000 / 3300 = 0.606
This loss rate is relatively large
How much is the current in the transmission line when the power of 4800kw is transmitted by 110kV High Voltage Transmission? If the conventional 220 V high voltage transmission is used, how much is the current in the transmission line?
I=P/U=4800kW/110kV=43.64A
I'=P/U'=4800kW/220V=4800000W/220V=21818A
