How we decide the Voltage of Transmission Line? Explain in detail the role of Distance, Line Voltage, Line Load etc.?

Question

Masruddin bakshi · Answer

The empirical formula for selection of transmission voltage relating transmission distance, transmitted power is given by-

V =5.5√ ((L/1.6) + (P×/Cosø × N ×))

Where,

V = Transmission line voltage in KV

L = Length of line in Kms.

P = Power to be transmitted

N = No. of circuits.

So by knowing transmitted power, transmission distance, power factor and no. of circuits transmission valtage can be obtained.
