Following are given datas,
Transformer kVA"= 50kVA"
Primary turns"(N1) = 400"
Secondary turns"(N2) =50"
Primary input voltage "(V1) = 2000V"
Frequency"(f) =50Hz"
2) Secondary voltage :
"\\frac{V2}{V1}=\\frac{N2}{N1}"
"\\implies V2=\\frac{N2}{N1}\\times V1\n= \\frac{50 }{400}\\times2000= 250V"
1) Primary current "(I1) = \\frac{kVA}{V1}=\\frac{50000}{2000}=25A"
Secondary current"(I2) =\\frac{kVA}{V2}= \\frac{50000}{250}= 200A"
3) We have emf equation for transformer as follows,
"V1=4.44\\phi f N1, Where \\space \\phi \\space is \\space Maximum flux"
There fore", \\phi = \\frac{V1}{4.44 f N1}= \\frac{2000}{4.44\\times 50\\times400}= 0.0225 \\space weber"
