  • How To Save Money And Get A Electrical Substation

Do you want to keep reliable electricity available for your home or business? If your answer is “yes”, then this article is for you. As you want reliable electricity, then you need to find the best Electrical Substation which is affordable as well as safe. I think now you become quite worried about how you can find the best Electrical Substation for your home. Don’t be so worried. We have exact and precise suggestions for you. By the end of this article, you will be able to know how to save money and get an Electrical Substation in your home. So, stay tuned.

What Is an Electrical Substation?

An Electrical Substation is a part of the generation, transmission, and distribution system. And it helps in power factor improvement, converting from AC to DC and from DC to AC. It also supplies power to the customer through multiple feeders after receiving high voltage and converting it to low pressure through transfer. After controlling the high voltage and high frequency, it is the job of the substation to distribute the electricity from the power station for various purposes.

So, it is necessary to ensure that households and businesses have access to reliable electricity. And substation helps on that as we know earlier. It is used to control machines, generators, and electrical circuits, among other things. And is primarily used to convert AC (alternating current) to DC (direct current) (direct current). Substations can be of many types. Such as, Generating Substation, Grid Substation, Secondary Substation, Distribution Substation.

How To Find The Best Electrical  Substation Equipment In Dhaka

Substations can be small or large. Transformers and related switches are installed into small size substations. Substations of various sizes are integrated with multiple types of transformers, equipment, circuit breakers, and switches. So, if you’re looking for the top Electrical Substation Equipment in Dhaka, you’ll need to know a little bit about the equipment and how it operates. You’ll also need to know how to compute the capacity of a substation. This information would help you in selecting the best option.


The substation’s main and largest component is the transformer. They’re available in a variety of shapes and sizes, as well as different voltage ratings. Transformers convert electricity to higher voltages for long-distance transmission and then back to lower voltages for customer use.

Transformer Selection

Transformer selection should be done based on the amount of load to be loaded. To help you understand, here’s an example:

If the load is equal to 60.45 kVA, a 600 kVA transformer must be chosen.

Why did we choose a 600 kVA transformer if our load was equal to.60.45 kVA?

The main reason for this is because a certain quality transformer is available in the market. Transformers are usually manufactured following the standard of transformer manufacturing companies. If you want the best quality Transformer, you can go for TOS Electrical Company. Almost every kind of transformer may be found there. 


Switchgear is a type of power disruption device that combines switching and regulating components. This category includes devices such as control circuits, measurement instruments, metering, regulation, and other electrical power system-related equipment.

In any contemporary power system network, switchgear protection is essential. Switchgear helps run electrical appliances in an efficient way and secures the equipment from overload Short-Circuit damage from power generation to distribution.

When the current and voltage are rapidly increased, the Switchgear is activated and instantly starts to control the circuit damage. This is where the inception of switchgear and protection devices happened in the newest form.

There are two types of switchgear i.e. high voltage and low voltage or, High Tension(HT) & Low Tension(LT). High voltage switchgear (HT) is used for electrical supplies like motors and big capacity electrical equipment that need more than 1000V AC. Low voltage switchgear (LT) is used for electrical supplies like motors and large capacity electrical equipment that require less than 1000V AC. Low-voltage switchgear controls electrical equipment that operates at less than 1,000 volts of alternating current.Here in TOS Electrical Company, you will get both HT switchgear and LT Switchgear at a reasonable price.

LT Switchgear selection

The capacity of the LT switchgear is calculated by multiplying the transformer capacity by 1.6. So, the switchgear capacity for a 600 KVA transformer will be-

1260 amperes = 600 x 1.6 amperes (A)

HT switchgear election

Here, HT switchgear refers to breaker selection. If the transformer is less than 630 KVA, the MCCB  (Molded Case Circuit Breaker)  / ACB (Air Circuit Breaker) transformer should be used; if the transformer is more than 630 KVA, the VCB  (Vacuum Circuit Breaker) transformer should be used. So here we have to use a VCB vacuum circuit breaker for 600 KVA transformers.

PFI Panel 

Due to the inductive load of various companies and large dwellings, the system’s Power Factor has been degraded. Here, PFI can help to get rid of that. It supports the recovery of the system’s deteriorated Power Factor.

PFI Panel Selection

PFI panel capacity is calculated by multiplying the transformer capacity by 0.6.

So, PFI is 600 x 0.6 = 480 KVAR for a 600 KVA transformer.

Frequently Asked Question (FAQ)

Is the substation noisy?

No. The substation is not excessively noisy. If you stand next to a substation, you could hear a low humming or buzzing sound coming from the powered equipment inside the fenced-in area.

What’s the difference between transmission and distribution lines?

Transmission lines are generally put on larger wood poles or steel towers, in addition to the voltage. Distribution lines are usually buried underground or installed on wooden poles like those found on city streets and alleys.
