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 …

Classification of Electrical Substation

Casualty of Electrical Shocks for Not Using Safety Equipments

In my last post I talked about the Electrical safety procedure and precaution when you are doing work. Now I am going to tell you what type of electrical safety equipment you need for work. Even I also discuses about, I there is any accident happened then what should you do with the person who is affected by sudden electrical shocks. So let’s start. Electrical Safety Gear: Beside other general safety attires, use electrical safety gears while working on electric Read More …

15 Important Electrical Safety Procedure and Precaution

In my last post I talked about Current and Voltage effects on human body and now I am going to tell you what Electrical Safety Procedure and Precaution you should maintain when you are at electrical work? 15 Electrical Safety Procedure and Precaution: Don’t depend only on switches; pull the plug from the socket. As an additional precaution, fuse must also be pulled where provided. Use a maintenance friendly safety panel board. Use cartridge fuse in panels. Never use re-writable Read More …

Current and Voltage Effects on Human Body

In my last post about Electrical safety I talked about the Electrical hazard and reason behind it. Now I will talk about the Current and Voltage Effect on Human Body. Let’s start with human body. Human skin resistance varied from 400 ohms for wet skin to 500000 ohm for dry skin. That’s means when you are wet then your body skin resistance will be 400 ohm and when your body skin is dry then your body resistance will be 500000 Read More …

Different Types of Cable Insulators

Electrical Cable can come with insulation or not. There are some type of over head transmission and distribution cable don’t have insulation on it because it stay up from ground level. But if a cable is passing through ground level and human and animal is crossing nearby then there is a big possibility that anyone can get Electrical Shock if the cable is not having insulation. Like cable insulation a cable insulator is also important equipments in power transmission and distributions Read More …
