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