1. An 11 kV, 3-phase alternative has Xd and Xq of 0.6 pu and 0.1 pu respectively and negligible armature resistance. It is delivaring rated kVA at 0.8 pf lag. Determine its generated emf.
2. Compute the distribution factor and coil span factor for a 3 phase winding with 4 slots per pole per phase and with coil span of 10 slot pitch.
