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?

WE are using a 63A MCCB(SIEMENS MAKE) for one of the feeder in LV substation panel.It is supplying to a lighting & power socket DB.Settings in the MCCB is Ir = 63 * 1 , Isd = 8 times of Ir , tsd = 0.5 sec( I2 t off). Sometimes this MCCB is tripping .But no trip in DB MCB. Can anybody tell me reason ? From where i can know about the MCCB settings?

why we step down voltage level from 33kv to 11kv and 11kv to 415v.Instead we can step down voltage from 33kv to 415v directly using single transformer?
