PRESENTATION TOPIC IS
TRANSMISSION LINE

3.
TRANSMISSION LINE
A transmission line is used for the transmission of electrical power from
Generating substation to the various distribution units.
It transmits the wave of voltage and current from one end to another.
The transmission line is made up of A conductor having a uniform
cross-section along the line.
Air act as an insulating or dielectric medium between the conductor.

4.
CLASSIFICATION OF TRANSMISSION LINE
1. OVERHEAD TRANSMISSION LINE
• Short Transmission Line
• Medium Transmission Line
• Long Transmission Line

5.
OVERHEAD POWER TRANSMISSION LINE
An overhead power line is a structure used in electric power
transmission and distribution to
Transmit electrical energy along large distances.
It consists of one or more conductors ( commonly
multiples of three ) suspended by lower or poles.
Since most of the insulation is provided by air, overhead
Power line are generally the lowest-cost method of power
transmission for large quantities of electric
Energy.

6.
SHORT TRANSMISSION LINES
• Line voltage is less than 20KV
• Length of transmission line is up to about 80km
• Capacitance effect are small or negligible

7.
MEDIUM TRANSMISSION LINE
• Line voltage is moderately high.
• It is greater than 20KV but less
• Than 100KV.
• Length of line is about 50 Km to
• !50 Km.
• Capacitance is significant.

8.
LONG TRANSMISSION LINES
• Line voltage is very high
(>100KV).
• Length of an overhead
line is more than 150km.
• Line constants are
considered uniformly
distributed over the whole
length of the line.
