Classification Of Transmission Line
1) Short Transmission Lines
2) Medium Transmission Line
3) Long transmission Lines
1) Short Transmission Lines
âž¡ Transmission Line Length 80 KM
âž¡ Operating Voltage 20KV
âž¡ Types Of Pole Used: wooden Pole. R.C.C Pole used.
âž¡ Types Of Insulator used: Shackle Insulator , Pin Insulator Post insulator used (some time as per condition Suspension Types insulator used)
âž¡ little distance and low voltage capacitance effect negligible
this transmission line Performance only consider resistance and inductance.
2) Medium transmission line
âž¡ Transmission line length between 80Km and 240Km
âž¡ Operating voltage 20KV To 100KV
âž¡ Types Of Pole Used: Steel Pole, Rail Pole, Steel Tubular Pole
âž¡ Types Of Insulator used: Suspension Insulator, Strain Insulator
âž¡ Line performance: Capacitance resistance and inductance consider
3) Long Transmission Line
âž¡ Transmission line length Above 240KM
âž¡ Types Of Pole Used : Lattice Steel Tower(galvanization coated steel tower)
âž¡ Operating Voltage Above 100KV
âž¡ Types Of Insulator used: Suspension Insulator, Strain Insulator
âž¡ Long Transmission line Constant are considered uniformly Not Lumped Over entire length Of line
