Here find some attached circuit of three phase cabinet which operation voltage is 400V /415V and have operated current 800A, fault current for 1 sec is 46 KA and have incoming and outgoing links with one phase Lighting and socket. I want to know is there some method that one can calculate...

I built a block diagram just have a look. Please have some look on the attached diagram and correct me if I am wRong.

According to you that the HV voltage from outside fed directly into the Switchgear, the two output of switchgear connected to the transformers at their respective points MIL & MIR. The transformers step down the voltage and send it to the respective LV panels and from LV panels output we get our...

You can find diagram here. Diagram attached in this post if you can not view in the above post.

Diagram Attached Dear now I have attached the diagram.

I think its main function is to reduce arc flash. But I want to know how it is connect with the transformer before or after. Can anyone explain it through the block diagram? If HV power lines enter in the substation first it connect to which one and after that which one ? [Switch gear...

Dear all, I want to know what is the function of motor in breaker and how it works. In which category it falls? I have studied many types of circuit breakers like MCB MCCB RCD RCBO VCB ACB etc. Figure of Motorized Breaker:-

What is the meaning of the CESMM3 Ref in BOQ of Transmission & Distribution? In the Bill of Quantities of Some project of Electrical Transmission and Distribution I came across the CESMM3 Ref when I searched in the net I know that it is the " Civil Engineering Standard Method of...

During exploring the Electrical Transmission and Distribution Network I came across the following terms. "Supply, installation, testing and commissioning of LV 600V/1000V insulation grade Panel Board consisting of following but not limited. I). 2700A single bus bar. II). 2x2700A Off...

Below is the typical diagram of a Substation in which MIL and MIR are with TR-1 and TR-2 respectively. Where TR-1 and TR-2 are the transformers whose function is to step down the voltage. I have also confusion about the flow(path) of the electricity with in substation. The confusion is that...

During studying the telecom underground cable network I came across the Optical Fiber Cable having the 144 fibers (single mode). I want to know why 144? Is this a Some standard to have 144 fibers in one cable? I have also viewed some of the datasheet having 144 fibers Optical Fiber Cable...
