Extra High Voltage Transmission Lines

Extra High Voltage Transmission Lines. After then,all the industrializedcountries all over the world have adopted the higher voltage levels. A long ehv ac line is always double circuit line with intermediate substations at an interval of 250 km to 400 km for compensating reactive power.

The transmission line performance has four parameters. Now a day, we are using extra high voltage (ehv) transmission lines for transmission of power between the generating station and distribution system.the main reasons behind it are: It is used to supply power in those areas having large fuel shortage following factors are needed to be considered while designing ehv transmission line

Those Transmission Lines Whose Voltage Level Is Above 1000Kv Are Categorized As Uhv Lines.

There are several advantages of extra high voltage transmission. Ehv lines are those transmission lines whose voltage level is between 230kv to 1000kv. Ehv transmission lines are used to transmit large blocks of power over long distances.

Extra High Voltage (Ehv) Or 'Extra High Tension (Eht)' Means The Voltage, Which Exceeds 33,000 Volts, Alternating Current, 50 Hz Frequency, Conditions Subject, However, To The Percentage Variation Allowed Under The Indian Electricity Rules, 1956

At the end point of primary transmission of power, in the substation , the step down transformers are used to step down the voltage level to 132 kv. The construction of super power stations of very large capacities necessities the transmission at high voltage for this we use ehv lines. The protection of extra high voltage transmission lines from lightning is of considerable importance as a result of the excessive flashover rate of such lines in the united states.

Later it was observed that the impact of such high voltage levels on the environment needed careful It is called primary transmission of power. Now a day, we are using extra high voltage (ehv) transmission lines for transmission of power between the generating station and distribution system.the main reasons behind it are:

At High Voltages Power Loss Is Also Reduced Because Losses.

A small part of the injected voltage that is in phase with the line When moving large volumes of electricity, it’s better to increase voltage instead of current intensity (amperage), in order to reduce energy losses and limit the total cost of transmission. • extra high voltage transmission lines are best suited for transmission of bulk power.
