Find (i) number of H.V and L.V turns per phase, (ii) e.m.f per turn (iii) full load H.V and L.V turns per phase. Cleon 16:58 ANSWER See details in the solution a. The core of a three phase, 50 Hz, 11000/550 V delta/star, 300 kVA, core-type transformer operates with a flux of 0.05 Wb. Find (i) number of H.V and L.V turns per phase, (ii) e.m.f per turn (iii) full load H.V and L.V turns per phase. 1. Number of turns per phase: V N = 4.44-1-4 where: N = number of turns per phase V = = voltage per phase f frequency (50 Hz) Φ += maximum flux (0.05 Wb) 2. E.M.F per turn: V E₁ = X Et where: N Et = e.m.f per turn
