# Why Transmission & Distribution Voltage 11KV, 33KV?

Transmission & distribution voltage These 11KV, 33KV, 66KV, 132KV Why is it Why they 11 Multiplier of Why? 10, 30, 60, 120 Not?? LET’S FIND OUT.

### Why Transmission & Distribution Voltage 11KV, 33KV, 66KV and 132KV?

Many people’s idea is the form factor 1.11 That is to say, the voltage patterns are the same.

• 10 x 1.11 = 11.1
• 30 x 1.11 = 33.3
• 60 x 1.11 = 66.6
• 120 x 1.11 = 133.2

In reality, this idea is not correct because of 120 Who’s the Volt? 1.11 By multiplying by 132KV Not coming.

And the form factor is RMS & Average value Of  Ratio। There is no point in multiplying it. So which one is right ??

Let’s give an example before that. Suppose you are from Rajshahi 500 I got contact to send me to Chittagong. Then what are you along with 500 I send ?? Of course not.

Because, on the way, there may be snatches or mangoes. So something has to be backed up. 50 You have to pay extra. Similarly, the power transmission/distribution companies are from the original voltage 10% Transmit additional voltage. Because they know well that the system will be lost along the way.
