a) A single phase transformer has 500 primary and 2000 secondary turns. The net cross-sectional area of the core is 70m2. If the primary winding is connected to a 60Hz supply at 620V, calculate:
i. The induced voltage in the secondary winding
ii. The peak value of flux density in the core
b) For the parameters obtained from the test of 20kVA 2600/245 V single phase transformer, define all the parameters refer to the high voltage side if all the parameters are obtained at lower voltage side are as below:
Rc =4.3Ω, Xm =j2.5Ω, R2 = 8.5Ω, X2 = j22.4Ω
