Why We Use Stone in Outdoor Electrical Substation?

Ok, you don’t need to be an Electrical Engineer to ask yourself that, Why They Use Stone in Outdoor Electrical Substation? 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 …

Advantage and Disadvantage of Grounded and Ungrounded Neutral System

If this is the first time for you then please read my previous post about Electric Earthing System. You will get enough idea for installing an earthing system for your home and industry. In this post, I am going to discuss the Ungrounded and Grounded Neutral System and there Advantage and Disadvantage and I will also discuss the preventive maintenance for the earthing system. So let’s go. Ungrounded and Grounded Neutral System: Generally earthing of neutral point of the transformer Read More …

Major Technical Consideration During Earthing System

If this is the first time for you then I will suggest you have a look at my previous post about the electrical earthing system. You will get a lot of ideas for a perfect earthing system. In this post, I am going to discuss some of the major technical consideration during earthing system and the factors affect of the earth resistance. So let’s go. Some Major Technical Consideration During Earthing System: First of all current carrying capacity. The current Read More …

Driven Electrode and Plate Electrode Types Earthing System

In my last post, I discussed Pipe Electrode Type Earthing System and Rod Electrode Type Earthing System. In this post, I am going to discuss another two methods of the earthing system and those are “Driven Electrode Types Earthing System and Plate Electrode Types Earthing System“. Driven Electrode Types Earthing System: This type of earthing system you can stable where soils have reasonable free from stone. For this method, you need to have a driven stud for all types of Read More …

Pipe Electrode and Rod Electrode Types Earthing System

In this post, I will discuss Pipe Electrode and Rod Electrode types of earthing system. Pipe Electrode Types Earthing System: When you are planning for pipe electrode types earthing system then your pipe electrode diameter should be minimum 38mm (1.5”) for the GI pipe and 100mm (4”) for the cast iron pipe. Now the minimum length of the pipe electrode should be 2.5m (9”). But the upper end is at a minimum depth of 1.25 meter from the ground level. Read More …

Methods of Electrical Earthing Systems

This is my second post about the electrical earthing system. In this post, I will discuss the requirement of electrical earthing system and methods of electrical earthing systems. Electrical Earthing System: Electrical earthing system is composed of, Earth Electrode: Earth Electrode is the last part for an earthing system. It is the part of which is always buried into the earth. There is some types of earth electrode are used like Pipe Electrode, Rod Electrode, Driven Electrode, and Plate Electrode. Read More …

Introduction of Electrical Earthing System

Electrical Earthing is one of the most essential parts in electrical engineering. You may deal will different types of electrical equipment and if there is no earthing system then you are at high risk. But having an earthing system is not enough. You have to calculate your overall load and individual earthing for each electrical equipment and machine. In my factory, we calculate all earthing system according to our government guideline from our outdoor substation to the individual machine. But Read More …
