But if you are an Electrical Engineer then you may need to answer this type of question to anyone. I got one question like this from my top management that, Why We Will Use 2-2.5 inch size Stone and Why Not 0.5-1 inch Stone? In this post I will discuss “Why We Use Stone in Outdoor Electrical Substation?” Explanation Read More …

33KV Outdoor Electrical Substation Equipment’s

I was responsible for making a 33KV outdoor electrical substation for my factory. In this post I will discuss all electrical equipment that we practically used in our outdoor electrical substation. First of all our demand load form government grid line was 3MW and there was a guideline for making this substation like transformer must be install in outdoor, well grounding system and some other specification. Don’t worry I will give you a video link that you can see actually Read More …

Why Strong Magnetic and Electric Field Effect Come From Electrical Substation

I already posted several article about electrical substation. If this is first time for you then read my previous post and you will how to setup an indoor and outdoor electrical substation and many more. In this post I am going to discus about the magnetic and electric field effect in an electrical substation and where it comes. So let’s go. We all know that an electrical substation usually has powerful magnetic and electric field. This electric and magnetic field Read More …

Protection for a Power Transformer

Power Transformer is an essential electrical component. Engineer like me, who only depend on transformer then it’s really important to keep the transformer active for 24/7. If there is any problem with transformer then all machinery inside of the factory floor will be silent and zero production will come. When you are having problem with your transformer then it may take long time to repair it. So it’s better to protect power transformer at first place. In this post I Read More …

Transformer Installation, Inspection and Commissioning

I already posted couple of article about power transformer. In this post I will discuss about the indoor transformer installation, inspection and commissioning. Transformer Indoor Installation: There is some specification if you want to install a power transformer inside a room. But you can do it when you get the permeation from the government. In my country if we are making a substation and our supply voltage is 11 KV then we can install our transformer inside a room. But Read More …

Transformer Schedule and Overhaul Maintenance

In this post I will discuss about the schedule and overhaul maintenance for a power transformer. So you just need to follow this procedure for a power transformer. For batter and smooth operation, this two type of transformer maintenance should perform.  Schedule Preventive Maintenance For Power Transformer: First of all visual inspection. Inspect the transformer very carefully. You may detect some fittings problem on transformer body and eliminate the problem. Drainage of transformer sludge, etc,. Form the conservator.

Some time it can be a question while you are in an interview board. In this post I am going to discuss all about the basic for this topic. I will provide a single line diagram for electrical transmission and distribution system by a .pdf format file and an AutoCAD .dwg Read More …

15 Essential Basic Requirement for a Substation

Electrical Substation is one of the most important parts in electrical engineering. In this post I will discuss about the some main 15 Essential basic components that really required in a substation. 15 Essential Basic Requirement for a Substation: For designing or making an electrical substation this following facilities must be adopted when it started. Always try to show a single line of diagram for all main electrical connection where Main Circuit Breaker or Vacuum Circuit Breaker (V.C.B) , Current Transformer (C.T), Read More …

Advantage and Disadvantage of Outdoor Electrical Substation

In this post I will discuss about the advantage and disadvantage of outdoor electrical substation compared with indoor substation. Advantage of Outdoor Substation: Outdoor Electrical Substation is located in Outdoor that’s means there will be no roof top. This following advantage can be found by an outdoor substation. The main construction work will needed is much smaller if we compared with an indoor substation. Always less quantity of building or infrastructure is needed. Insulation cost for a switchgear and others Read More …
