Dear sir, my knowledge about cable size determination is limited. Though I read examples I could not calculate the Cable size required for electric driven pump 40 KW, 380 Volt, 50 HZ, 50 meter from transformer and it is three phase star delta starting. Please help as there is no one in my surroundings to help.
What are the applications of autotransformers?
- two pumps must work with them at the same time but if the first pump start the second pump must delayed for some time to start also , with motor rated power = 90 KW and rated voltage = 380 V and rated power factor = 0.85 lag please draw the power and control circuit for it and determine all circuit components parameters that you use it
How to synchoronize the generator (with gcb,GT) to grid????? ????? from Grid iam getting power (rated 400kv/20kv) through GT and its goes to UAT.,,ST.,, now my generator(rated 20kv ) ready.,, now iam closing my GCB.,, in GT iam suddenly giving 20kv on that Gt.,, what will happend
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.
