Why generally the transformer primary is connected in star & secondary in delta
(1)The demand for electricity , the amount of renewable generation available, the amount of fossil fuel generation available and the cost of the fossil fuel generation are shown in table below period(hrs) demand(MW) renewable (MW) fossil- fuel(MW) cost of fossil fuel(MW) 00.00 - 01.00 2000 1800 2000 30 01.00 - 02.00 2300 2500 2000 30 02.00 - 03.00 2500 2700 2100 45 03.00 - 04.00 2900 3100 2100 50 04.00 - 05.00 2700 2600 2500 45 05.00 - 06.00 2400 2000 2700 50 06.00 - 07.00 2200 1800 2000 36 07.00 - 08.00 2100 1600 2000 36 Assuming that the renewable generation incurs zero cost, determine an optimal generation schedule(specifying the amount of renewable generation and fossil fuel generation used in each period, the cost for each period and the overall cost for 8 hours.)

2 Answers Makino Auto, SAL Steel Power, Sapphire Group,
i have 3, 75hp motors and 10, 15 hp motors....and to run this motors continously with a generator how much rating(kva) of generator will suiteble....?
what is the meaning of knee point in current transformer and how to calculate?
if the 10 hp motor name plate indicates rated current as 13.6 amp the what will be the thermal relay setting? Why? And in how much time relay will trip at the set value?
During the troubleshooting of an inoperative shunt generator, you found the voltage to be 2+ volts; what is known from this. Is it (1). odds are the armature is good (2). odds are there is no field current flowing in field windings (3). odds are the armature is bad (4). both 1 & 2 are correct (5). both 2 & 3 are correct
