Question

poin A D.C. generator is to supply a load of A 367 KW at 300 V. If you know that the Power Developed in the armature is 372 Kw and the core and mechanical losses is 2 KW, how much is the electrical losses? O 3 KW O 70 KW O 5 KW O 2 KW points For the magnetic circuit shown in the Figure: The flux in the core is 0.03 wb and the current is 3 A. If the total equivalent reluctance of this magnetic circuit is 30 kAT/wb, how much is the number of turns?

Answer 1

Given: lower lower developed in to be supplied armature 372kw foran 367 kw We thow that lower developed lower suppliedt losses. Losses & Core loss & mechanical Copper loss or losses Elebucal lossest Total losses = 372-367 -5kw Guven core loss of mechencial loss = 2kw .: Electrical losses or copper loss tota loss - [core loss. & mechanical loss] = 5-2 = 3 kw
