Question
  1. 26. An unbalanced star-connected load is supplied from a symmetrical 400-V, three-phase, three-wire system. The impedances are: (1+J2)ohm between line R and neutral point of load: (2+j3)ohm between line Y and neutral point of load: (3-j3)ohm, between line B and neutral point of load. Calculate the current in line. B. Phase sequence RYB.

[35.5 A] Answer

26. An unbalanced star-connected load is supplied from a symmetrical 400-V, three-phase, three-wire
system. The impedances are: (1+2) between line R and neutral point of load: (2+3) 02 between line Y and
neutral point of load: (3-j3) 22, between line B and neutral point of load. Calculate the current in line. B. Phase
sequence RYB.
