Compact Substation Manufacturers

Compact Substations are frequently used by users around the world because of ageing equipment and rising demand, the majority of companies around the world are looking for ways to replace or expand their substation capacity.

However, there is no denying that transmission infrastructure is difficult to modernise because it is a costly process. As a result, the power industry is seeking more cost-effective options, and a compact substation is one of them.

What is a Compact Substation?

A Compact Substation can be defined as a collection of electrical equipment installed on a trailer or platform. A compact substation is integrated and carefully tested in a factory setting to verify that it is capable of completely energising upon delivery to the required site. A small substation has more advantages than a traditional substation, such as shorter construction times, fewer area requirements, and improved safety.

Compact Substation is a highly reliable substation solution for voltage of 330V, 500V, and 650V and is based on the HT switchgear series. Compact substations are used in secondary distribution networks to convert energy from MV to LV or LV to MV. Its superior quality and higher reliability make it an ideal solution for applications with heavy-duty requirements and economic savings as well as to fit into smaller spaces.

Compact Substation has a compact design and can be installed on the wall. It is a complete solution for the quick installation of high-voltage switchgear. It has been designed to be customised by the end-user and offers an easy way to connect with all types of switchgear.

How do Compact Substations Work?

Switching is a critical function of small substation transformers because it allows you to shut down a feeding circuit when there is a demand for the load to protect the generating plants.

Furthermore, because switching high voltages can be dangerous, circuit breakers such as oil circuit breakers and air circuit breakers can be used to reduce arcs.

High voltages can be used to step up and down the voltage for the distribution and transmission of electricity, even across great distances. As a result, the current can be minimal, resulting in low transmission losses. This signifies that the current available is insufficient for normal consumer use and that the voltage must be increased or decreased.

What are the Categories of Compact Substation?

The Compact Substation is a complete system that includes three compartments (MV switchgear, transformer, and LV distribution board) that are connected directly to a metallic chassis without the use of cables.

Compact substations are divided into three categories:

Indoor Compact Substation

Equipment on a moving (wheeled) metallic chassis with three compartments (MV switchgear, transformer, and LV distribution board).

EVR Power has come with a new and improved substation, the idea of the Indoor Compact Substation is to serve you with high-quality equipment, quick delivery times, and competitive pricing. With a fully-equipped MV switchgear compartment and LV distribution board compartment, you can rest assured that your power will be stabilized, your downtime will be reduced, and all of your equipment will stay safe.

Outdoor Compact Substation

We live in a world of space constraints. With the growing demand for higher power, we need compact substations to quickly and efficiently provide power where it is needed.

Designed for outdoor use, the Outdoor Compact Substation doesn’t require a ceiling or roof and it provides high-level protection from weather conditions. This type of compact transformer substation is very much high in demand.

Compact Underground Substations

Underground substations are prefabricated concrete compact underground substations. The structure is designed to be a smaller, more robust and more economical substation with the outdoor operation and reduced dimensions in order to improve exploitation circumstances.

This substation has been specially designed to use the existing terrain and artificial structures in the area to its advantage, achieving reduced dimensions and enhanced exploitation circumstances. The installation’s modularity will allow it to be completely dismantled, transported, and assembled on-site without major problems.

Due to the increase in volume consumption of electricity in India, different types of compact transformer substation manufacturer in India has increased significantly. Especially in Maharashtra, Chennai and Gujarat compact transformer substation manufacturer has increased considerably by 5% to 7%.

4 Significant Benefits of Compact Substations

Compact substations are chosen over conventional substations because they are a comprehensive solution that can readily fit into any configuration based on the customer’s needs.

Environmental Risks Have Been Removed

A typical substation necessitates digging the ground, which interferes with natural drainage, however, this is not the case with a compact substation. Because the device is contained in a tamperproof metal container, it helps to eliminate various environmental dangers such as exposed grounding conductors and fencing.

Furthermore, the container aids in the prevention of oil spills that could contaminate the earth.

Overall Costs are lower

These units are pre-assembled, which helps to save expenses as compared to a traditional substation. As a result, the expense of transporting multiple parts and field wiring, as well as on-site testing, is reduced.

They’ve been carefully built to speed up the installation procedure and minimise building time by a large amount. Furthermore, they sped up the testing procedure on the job site, saving both money and time.

Safety and Convenience

There are no concerns with equipment relocation with a small substation, and there is no need to deconstruct or rebuild a standard station. This unit is lightweight and mobile, making it extremely convenient to use.

Finally, it includes safety measures such as a covered ground conductor, fully contained equipment, built-in oil containment, covered grounded conductors, and a few exposed parts. Overall, it creates a safe environment for everyone in its vicinity.

A Tiny Imprint

Compact substations are designed to take up as little space as possible. It’s also not as difficult to fit them into varied layouts as it is with traditional substations. Transporting them to the desired position is simple, and the covered equipment eliminates the need for additional electrical clearances.

EVR Power’s Compact Substation Specifications

EVR Power’s transformer is not your typical transformer when it comes to compact substation standards. Instead, they resemble miniature substations that provide power to the user directly.

Improved Air Conditioning

Unlike traditional transformers, a transformer works by increasing demand for its cooling capabilities through an underground cavern. This means that these transformers can tolerate voltage and load spikes.

This implies that ordinary air-conditioning is ineffective, which is why water-cooling systems were developed.

Powerful

The installation of three 500kV autotransformer transformer banks is a regular problem. As a result, the compact substation transformer is highly handy when it comes to saving space.

Is it, however, a threat to its power?

The short response is a resounding no. Under some conditions, compact substation transformers can be just as powerful as standard substation transformers.

Fewer Losses

Because the criteria for short-circuit strengths are great for requesting, every single transformer should be able to withstand a particular amount of short-circuit load, compact substation voltage levels are simply on another level.

However, this means that autotransformers for subterranean substations can withstand an impedance of around 22%. In layman’s terms, this indicates that the unit substation transformer will continue to perform normally even if it is subjected to a load that is 22% more than typical.

Enhanced Control

There is no doubt that a high impedance is being highlighted as a difficulty for stray loss reduction, and this is fully backed by a 3D magnetic model that protects its structure design, especially as the tank and clamping frame sizes grow.
