[Answer] Why Is Transmission Line Voltage a Multiple of 11?

Hey there, looking for the answer of Why Is Transmission Line Voltage a Multiple of 11? question then you are at the right spot. Here in this article will find the detailed 300 words answer of the following question, stay with us till the end and thanks for the reading the article.

Why Is Transmission Line Voltage a Multiple of 11?

It is due to the form factor (which is determined by the shape of the wave form), which in the case of DC is one. For example, the form factor for Ac (sinusoidal waveform) is 1.11. However, for simplicity and to use less calculation and equipment, we consider form factor 1.1, which means that transmission voltage is a multiple of either 1.1 or 11.

Due to the form factor

You’ve probably heard many times that transmission line voltage is caused by the multiple form factor of 11. Let us explain below. The form factor value is 1.1. Because the Form Factor is the ratio of RMS to average voltage or current.

Why is 11kV 33KV 66KV?

This is because at 11KV, 33KV, or 66KV, losses are allowed for, resulting in the square of current and resistance of the conductor on the line from the sending end to the receiving end.

Why we generate only 11kV?

Electricity is generated at 11000 V, or 11 kV, at the generating stations. It is cheaper to generate electricity at a lower voltage and then increase it for transmission. As a result, the majority of power plants around the world are designed to operate at 11kV.
