We all have seen transmission and Distribution lines In transmission lines the voltage is high and current is low(to reduce I^2r loss) and in distribution lines voltage is low but current is high however the size of transmission wires is bigger than that of distribution wires even though the amount of current carried by the distribution lines is more than that of transmission lines why?

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
