A synchronous generator with 30 MVA, 11kV 3system having an impedance of 1.5Ω. What is percentage impedance? (Give answer upto two decimal)
A 150 MVA, 11 kV synchronous generator has an impedance of 4Ω. What will be the p.u impedance at 250 MVA and 10 kV? (Upto two decimal)
A single line diagram of a power system network is shown below
The transformer T2 is a bank of three single phase transformers. The rating of each transformer is 100 MVA, kV with impedance X = 0.1 per phase (p.u)
The rating of generator, T1 and transmission line is as follow.
Generator G: 300 MVA, 20kV; X = 0.1Ω
Transformer T1(3): 350 MVA, kV; X = 0.1Ω
Transmission Line: 0.5Ω, 230 kV.
What will be the per unit reactance of the transformer (in p.u) ______? (Upto two decimal). Take base values as generator base.
The main motto of the reactance diagram is
Which of the following is the single line diagram with the data obtained as shown in figure below. (Assume base values = 50 MVA, 13.8 kV)
What will be the p.u impedance diagram of the transformer shown below?
