What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
How much must be the distance between two conductors of 11kv line?
600mm is the distance between two conductors in 11kv line
How many suspenssion type insulation used in 66kv transmission line?
one insulator unit can bare 11kV. such that 66kV tx line needs 6 insulator units.
What is surge impedance in power systems?
Actually surge impedance is present in a transmission line due to the capacitance of transmission line. Now this capacitor attends the reactive power of the transmission line to energise its magnetic flux. now due to the flux the impedance will increase and the power is reactive too. due to the impedance loss is more.
How do you tell if the power steering line is leaking or if it is the transmission line is leaking?
Check the power steering and transmission fluids to make sure that they are at correct levels. If the leaking one is not low, then clean the areas where fluid is showing and keep checking to see where the leak is. Check all line connections in both systems for visible leaks.
How the section of a transmission line can be used as lumped circuit element?
Actually in networks we will consider the elements like resistance, inductance, capacitance as lumped elements for simplicity, like this in power systems we will consider the transmission line parameters(resistance, inductance, capacitance) as lumped elements, because we will calculate all the parameters of power systems with respect to receiving end or sending end but not with respect to middle of the line. If a fault occurs on transmission line then we should not consider the lumped elements of that total transmission line, we should consider the lumped elements from sending end to the point where the fault is occurred.
Why phases in transmission line are transposed?
Image result for Why phases in transmission line are transposed?Transposition is the periodic swapping of positions of the conductors of a transmission line, in order to reduce crosstalk and otherwise improve transmission. ... Transposition also equalizes their impedance relative to the ground, thus avoiding one-sided loads in three-phase electric power systems.
Why 3phase line used in transmission?
owing to its advantages of carrying large amount of power compared to the remaining systems .. 3 ph is widely used.
Why does a 2003 impala transmission loses power?
TRANSMISSION LINE LOSSES
What is the formula for calculating power loss in transmission lines?
The formula for calculating power loss in transmission lines is Ploss I2 R, where Ploss is the power loss, I is the current flowing through the transmission line, and R is the resistance of the transmission line.
Cg electricity board junior engg result?
what is the value of the capacitance in the transmission line to earth, i know it is different for different values ,i mean for 11KV,33Kv and so on, but don't know how much
What is uncompensated power transmission line?
