can any one help me for my ups inter view , list out few basic technical ups question with answer.
1 2535HOW TO CALLICULATE RESITENCE,REACTANCE AND IMPEDENCE VOLTGE OF TRANSFORMER 13.33 KVA 144/240 VOLTS 93/56 A WITH FORMULA
ISRO,
1501if any one phase of the 11kv/415v distribution transformer not delivering the supply voltage what will happen
2 4117why we take movement of rotor always in counter-clockwise direction in 3-phase induction motors?
1488Why we apply only reduced voltage to the alternator while conducting slip test ? also the current increases to a larger value with reduced voltage itself Why ?
1 6215What are the main problems in distribution? I have to do an assignment so which problem should I choose? Like power factor problem etc.
4 4533In the diesel generator if there is an AVR (auto voltage regulator) gone faulty, in this condition is there any way to generate the voltage from the alternator? I need a brief explanation can you please help somebody

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
