Answer / manish meena

1)short transmission line: when the length of an overhead
tranmission line is about 50 km and line voltage is <20kv
2) medium transmission line: when the length of an overhead
transmission line is about 50-150 km and line voltage is
>20kv<100kv.
3) long transmission line: when the length of an overhead
transmission line is about more than(>150km) and line
voltage is >100kv.
Main losses are corona losses,losses due to inductance and
capacitance(but these are negligible)

Answer / percy

short 0-80 Km
med 80-240 Km
long above 240 KM


losses I*I*r
losses occuring in capacitance b/w two or three conductors
