Total: 65

An alternator with internal voltage of 1‌angle‌delta1 p.u. and synchronous reactance of 0.4 p.u. is connected by a transmission line of reactance 0.1 p.u. to a synchronous motor having synchronous reactance 0.35 p.u. and internal voltage of 0.85‌angle‌delta2 p.u. If the real power supplied by the alternator is 0.866 p.u., then left(delta1−delta2‌right) is _____________degrees. (Round off to 2 decimal places.) (Machines are of non-salient type. Neglect resistances.)
