A busbar is a kind of copper or aluminum conductor rod, which collects Electricity from one or more circuit and distributes it. Today we will discuss the busbar size calculation chart pdf. Busbar Calculation Busbar calculation/selection is done in two ways: Directly based on current value andBased on transformer rating Busbar Size Calculation...

There are some calculations for selecting circuit breakers for LT and HT sides. Today we will discuss cable size and circuit breaker selection and also the circuit breaker rating chart. There is no need for any calculation for the HT section circuit breaker and it is very easy to calculate....

A single line diagram is very important in a power system. We can easily visualize or describe the three-phase power system in a single-line diagram. Today we will discuss the substation three-phase single-line diagram explanation. Instead of three wires for a three-phase line, one wire is used for describing the...

We know that many elements are used for the transmission and distribution of Electric power from the power plants. So, today we will discuss what are the components of a substation? Here is a list of substation components: BusbarIsolatorACR (Automatic Re-closer)PT (Potential Transformer) CT (Current Transformer)VCB (Vacuum Circuit Breaker)TransformerInsulatorLightning arresterPFI (Power Factor...

An electrical substation is a part of the Electrical generation, transmission, and distribution system. We can turn voltage from high to low or low to high and do various important works with the help of a substation.  The substation is situated between powerplant and customers. Where various electrical devices and...

It is very common to have questions like: can you plug a microwave into an extension cord? Today I am going to answer this question. Is it Recommended? When utilizing a microwave, you will frequently try to find an electrical outlet nearby. This isn't always achievable, however. Consider utilizing an extension...

We all have seen the cross-arm of towers. Cross-arm is like a tower's hand, where it holds an insulator, insulator pin, wire, bird protector, lightning arrester. Generally, a cross-arm is made of wood and steel. And connected with a pole or tower horizontally. Today we will discuss cross-arms in transmission...

We have already known about Bridge Rectifier With Capacitor Filter in our previous article. I am going to discuss another way to rectify an AC signal. This is center tap full wave rectifier with capacitor filter. What is center tap full wave rectifier? How it will rectify an AC...

The transmission and distribution course is very interesting. There is a lot to know about transmission lines. When we travel to the countryside, we see transmission lines in the middle of green fields. Which is very much eye soothing. Today we will discuss the transposition of transmission line. War of...

Have you heard about people with dual personalities? It's very tough to handle this type of person who doesn't bear a fixed manner. In our electrical technology, there is also a double standard character which is alternating current. But we have also arrangements with a view to rectifying this...

Would you be able to rotate a motor forward and reverse direction for a particular time? For this action, you have to acquire a clear conception of the forward-reverse control wiring diagram. Let's discuss this topic today. Hope you will enjoy it. Why We Rotate a Motor in Forward-Reverse Direction? The...

This article's sole purpose is to enlighten the facts and truths about Nikola Tesla's anti-gravity. The past is always about what we hear from others.
