1.	A 15kVA, 8000/230 V distribution transformer has an impedance referred to the primary of (80+j300)Ω. The excitation branch component with reference to primary side are Rc=350kΩ and Xm=70kΩ. If the connected load is a capacitor of reactance −j3.5 Ω and primary voltage is 7967 V, then percentage voltage regulation of transformer will be _________ -7.07
Answer» A 15kVA, 8000/230 V distribution transformer has an impedance referred to the primary of $(80 + j 300) Ω$ . The excitation branch component with reference to primary side are $R_{c} = 350 k Ω a n d X_{m} = 70 k Ω$ . If the connected load is a capacitor of reactance $- j 3.5 Ω$ and primary voltage is 7967 V, then percentage voltage regulation of transformer will be _________ -7.07

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
