Send Inquiry Send Inquiry.I was responsible for making a 33KV outdoor electrical substation for my factory. In this post, I will discuss all the electrical equipment that we practically used in our outdoor electrical substation.
First of all our demand load form, the government grid line was 3MW and there was a guideline for making this substation like transformer must be installed at the outdoor, well grounding system and some other specification. So our first electrical equipment was ABS Automatic Break Switch and it was responsible for isolate the main incoming line manually form our substation.
ABS used to install at the top of the electric pole. Then there is electrical equipment name ACR Automatic Circuit Recloser and it was responsible for isolate the main incoming line before the substation.
33KV ISOLATOR WITH EARTH SWITCH WITH STRUCTURE
But it was an automatic control circuit breaker and it uses to power by a PT which also installed at the top of the electric pole. No problem you will find red color equipment in the video. These two types of equipment installed before starting our outdoor electrical substation. ACR output three-phase line will come to the three individual lightning arrestors which you will find at the top of the electric pole and then you will find another electrical equipment called Isolator.
With the Isolator, there is another electrical equipment name Earth Break Switch and it installed with an isolator with the interlock system. When the isolator is operational then the earth brake switch will not operate.
Earth break switch mainly uses for grounding purposes if there is any maintenance in the outdoor substation. If there is any maintenance in our substation we use to open the isolator and then we close the earth break and start working. You will find another set of Lightning Arrestor for the same work.
You will find some earthing pit inside the substation and we have 17 earthing points across the substation but the lightning arrestor grounding system is separated from the main interlink earthing system.

Electrical and Physical Arrangement: For any electrical one-line diagram there are usually several possible physical arrangements. The shape of the site April 12, In this post, I will discuss all the September 4, I already posted several articles about electrical substations.
If this is the first time for you then read my previous post August 22, In my last post about electrical substation, I discussed what is a substation, why we need substation and the most common August 3, May 25, Installation: The GIS is usually installed on a monolithic concrete pad or the floor of a building.The substation would be a combination of switching, controlling, and voltage step-down equipment arranged to reduce sub-transmission voltage to primary distribution voltage for residential, commercial, and industrial loads.
To step down the 33kV primary voltage to 11kV suitable for distribution purpose. Circuit breakers were needed so as to disconnect and isolate the faulted section. Sulphur-hexa-fluoride SF6 circuit breakers were chosen. The incoming and outgoing circuits were connected to busbars. Chosen feeder system was the loop type. Feeders were paired so as to form a closed ring and with each fitted with a circuit breaker. The 11 kV bus was sectionalized into two sections each being fed from the different power transformers.
Each one of the feeders constituting a pair was to emanate from one of these sections and the other from the other section because of the following reasons:.

Each feeder was first assigned an average capacity of 2. I love to read your portal. The portal itself is so useful and it goes along with me everywhere … It is nice for students to see the real implementation of what they study. Search for:.

Substation specific design The substation would be a combination of switching, controlling, and voltage step-down equipment arranged to reduce sub-transmission voltage to primary distribution voltage for residential, commercial, and industrial loads. A bus sectionalizer in form of a circuit breaker and disconnector was installed between the two bus sections which would make it possible to join or separate the two sections while in service.
Therefore the number of feeders for Fahari city substation was determined by the substation full capacity and the estimated full load on each. Related EEP's content with sponsored links.

I agree.We considered incoming power at KV and the power was transferred to main bus through isolator-circuit breaker-isolator combination.
The power is then fed into a 33KV bus from which different loads were tapped. In the process, the surge impedance loading of KV and 33 KV lines were calculated and they were used to estimate the maximum power that can be transferred by one transmission line. The design of the entire substation was made keeping in mind the most basic requirements of a proper substation including the civil and domestic requirements.
Starting from the generating stations to the end users, voltage is needed to be stepped up and down several times in various substations. This ensures efficient transmission of powerminimizing the power losses. The power factor is corrected here and the voltage is stepped down to 33KV and power is then transferred to distribution system of the grid to meet the requirements of the end consumers at their suitable voltage.
