electrical engineering giving priority for insulators
rather than conductors, why ?
Answer Posted / swetha
Selection of Insulation of conductor is depend on
Safety ,reliability,location where it is used.So electrical
engineer give more priority to the insulator then a
conductor

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.
