Why is 11kV 22kV 33kV 66kV 132kV in India?

Why is 11kV 22kV 33kV 66kV 132kV in India?

This is all the electrical engineer must know, why in India 11kV, 22kV, 33kV, 66kV, 132kV like that we have different level of voltages. Normally people say it is due to the sinusoidal form factor, the form factor is equal to 1.11, but thats wrong let see….

What is the maximum transmission voltage in India?

Transmission voltage in India (highest) is 765 kV AC and these lines are erected by Power Grid Corporation for interstate connections throughout India. DC transmission voltage (highest) in India is 800 kV .

Why are transmission lines operated at very high voltages?

The primary reason that power is transmitted at high voltages is to increase efficiency. As electricity is transmitted over long distances, there are inherent energy losses along the way. The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors.

What is the transmission voltage in India?

In India, genereation voltage is generally 11 kV but for power transmission 33 KV, 66 KV, 110 KV, 132 KV, 220 KV, 400 KV and 765 kV are used. Transmission voltage in India (highest) is 765 KV AC and these lines are erected by Power Grid Corporation for interstate connections throughout India.

What voltage is 11kV?

High voltage (HV) – means and voltage exceeding 1kV a.c. or 1.5kV d.c. Extra high voltage (EHV) means any voltage exceeding 220kV….Standard line voltages.

Line Voltages	Usage
11kV	Used for urban and rural HV distribution
22kV
12.7kV (SWER)
22kV

What is the generating voltage in India?

For Europe and India, 11 kV and 50 Hz is the dominant standard generator voltage and frequency.

How many volts does a transmission line have?

Transmission line voltages vary from 44,000 to over 765,000 volts. The higher the voltage, the more electricity the line can carry.

What is 11kV voltage?

The voltage between any two live conductors is often referred to as the “line voltage”. For instance, in an 11kV three-phase system, the voltage between any two live conductors gives a line voltage of 11kV while the voltage between any live conductor and neutral (or earth) gives a phase voltage of 6.35kV.

Are there any voltages that are multiple of 11?

First of all, It is not true that all the transmissions and distribution voltages are multiple of 11. In most case, they are multiple of 11 such as 11kV, 22,kV, 33kV, 66kV & 132kV.

Why is the form factor equal to 1.11 in India?

This is all the electrical engineer must know, why in India 11kV, 22kV, 33kV, 66kV, 132kV like that we have different level of voltages. Normally people say it is due to the sinusoidal form factor, the form factor is equal to 1.11, but thats wrong let see…. Form Factot is nothing but a ratio between RMS value and Average Value is called form factor

What are the advantages of high voltage transmission?

The high voltage transmission has some advantages as compared to low voltage and high level of current transmission i.e. low power factor, corona loss, skin effect, l 2 R (Line losses), Heat etc. The only disadvantages of high power transmission is distance, insulation of the line and height of towers.

What is the form factor of electric transmission?

Form Factor is the ratio between the R.M.S (Root Mean Square) value and average value of electric quantity (Current or Voltage). Mathematically, It can be expressed as
