3 Phase Distribution Board Wiring Diagram

Hello every one... Today you will learn about the 3 phase distribution board wiring diagram. Not only a diagram but also a video tutorial in Urdu/Hindi language. So what's you need... In the today 3 phase panel board wiring diagram. You will learn about a 3 phase distribution board. In the three phase distribution board we have 6 MCCB (molded case circuit breakers). In which 600 Ampere circuit breaker as main circuit breaker. Five 100 A MCCB circuit breakers, volt meter 0 to 500 VAC, 200/5A current transformer and Ampere meter. Light indicators and earthling connection.

3 Phase Distribution Board Wiring Diagram

In the below Three phase panel board wiring diagram. The complete wiring shown step by step. In the diagram we use wired the MCCB circuit breakers. The all wiring done with Bus bar. In the diagram the two voltmeter wired for 3 phase voltage measuring.

(note that the Red, Yellow, Blue color is used for Line1, Line2, Line3. The black color is used for neutral and Green color is used for the earth wire.)

The current transformer is 200/5A and also same ratio of CT type ampere meter. The ampere meter class 1.5.

Three phase Distribution board wiring Diagram explained Complete in video

For complete understanding the 3 phase panel board wiring diagram, watch the below video tutorial. In the below video tutorial I explained the complete diagram In Urdu/Hindi language.




I hope after watching the above distribution board wiring diagram video tutorial. Now you will be complete understood. However you can ask your question in  the below commenting system. Thanks for visiting and watching the video tutorial.

How to Choose Suitable Wire Size for Transformer Winding

Today I am sharing with you the simple method of choosing the suitable wire size for transformer for winding. Or how to chose the wire size for transformer winding. To chose the suitable wire size for transformer primary winding and secondary winding is first and mine point of designing a transformer. Today I will share with you simple table which help you to select the wire size for a transformer.

As you know that we already talk about the turn per volt formula. however in this post we will also use in example to make it easy to understand. And if you would like to learn it complete then watch the below video tutorial first in Urdu/Hindi language.

How to chose the wire size for transformer winding?

Before choosing a transformer we need to think about the some main points…
For example

The working time of transformer

Before to chose the wire size for transformer, you need to find out how much time the transformer will work. If your transformer work for 12 hours then you need to chose the wire size according the 12 hours time and if the transformer working time is 4 to 6 hours then you need to select the wire size according the 6 hours time….

The installation place of transformer

You must be think about the transformer installation. mostly we fix he transformer in box. So if the transformer install in box. Then air flow in box. Also don't install transformer near other machine which produce the heat….

Here I am sharing with a transformer winding current table with transformer wire size gouges according the 1000 circular mils per ampere with transformer winding current. This is suitable for a transformer which is used for 4 to 6 hours. And if you want to use the transformer more than 6 hours then use a number high gauge.

How to select the suitable wire size for transformer winding

Here I clear everything using an example.

Transformer Wire Size Selection

For example: Bobbin Size 1.5” x 2” L x W = 3
Primary voltage is : 220V
Secondary Voltage is : 13V + 13V
Secondary Current is : 7A
Primary current : ?
First Find out the Primary current
Formula : SI x SE / PE …. So 8.2 x 26 / 220 = 0.969A

Primary Turns & Secondary Turns Per Volt = ?

Bobbin Size 1.5” x 2” = 3 So 7.5/3 = 2.5 turn per volt
But Due to Loses we get 8/3= 2.66 turn per volt
Primary Turns is 2.66 x 220 = 586
Secondary Turns 2.66 x 13 = 35 + 35
According To Table 1000 Circular Mils

Suitable wire size for Secondary is 15 SWG
And For Primary 22 SWG

Now i hope you will complete understood the chose the suitable wire size for transformer winding. Now if you have question then you use the below comment section..

What is Voltage Drop in Hindi & Urdu

Hello every one. Today I am writing about the what is voltage drop. And I explain the voltage drop in Hindi & Urdu with a video tutorial. In the my last post I talk about the voltage and current. And I explained about the voltage and current in Urdu/Hindi. In the this post I going to share a video tutorials with you in which i complete explained the voltage drop with simple and easy example.

What is Voltage Drop in Hindi/Urdu

The voltage drop is one of big problem in electrical. In electrical devices and wires we have some  resistance and due to risistance its generat some voltage drop. Before to calculate the voltage drop we cannot chose the suitable size of electric cable. I also provide the calculation video about the selection of cable and circuit breaker in my last post. You can also read by using the below link

In the today post I am sharing with you a video tutorial which is about the basic concepts about the voltage drop. You can also watch this video in our YouTube channel. But the main reason behind sharing this video on this blog is that. Many of viewers visit our blog getting video tutorials. In the below video tutorials I explain the voltage drop in Hindi/Urdu language.


I hope after watching the above video voltage drop explanation video tutorials. Now you will be complete understood. However shown I am sharing with you the simple and easy voltage drop calculation formulas. So stay tune with us.....

What is Voltage and Current in Hindi - Urdu

Today in this post I am going to explain what is voltage in Hindi, what is current and resistance in Urdu/Hindi language. This post help you complete to learn about the difference between the voltage and current in Hindi. This post contain- a video tutorial which clear all about the voltage, current, ampere, resistance and power (watt). And IN SHA ALLAH after this post and watching the video tutorial, you will be complete understood about the voltage, current and resistance in Urdu/Hindi language. In the video you will got some simple example which will help you to understand it easily.
