[2015: 2 Marks, Set-2]2.37 A balanced (positive sequence) three-phaseAC voltage source is connected to abalanced, star connected load through a star-delta transformer as shown in figure. The line-to-line voltage rating is 230 V on the starside, and 115 V on the delta side. If themagnetizing current is neglected andIs = 10020° A, then what is the value onTp in Ampere?wWMa) 502300(c) 5013230°(b) 502-30(d) 200230°[2015: 2 Marks, Set-2] |
