A majority of companies in the world are seeking ways to replace substations or increase their capacity because of aging equipment and also growing demand. But there’s no denying the fact that transmission infrastructure cannot be easily modernized as it is a costly process. Therefore, the power industry is looking for more cost-effective solutions and one such solution is a compact substation.
What are Substations?
Substations are generally like actual commute or public vehicle stations. This is because like people, there is a need for a public vehicle to get to the location. When it comes to the situation of electricity, substations like compact substation transformers are commonly used for transporting electricity at long distances.
The place of the substation is where electricity is being produced, and it also can be the location where the consumer is found. When it comes to the spread of electricity, it is rated as a very fast and high voltage with low currents.
The substations are where the voltages are raised to high values.
It’s achieved by utilizing:
- step up transformers
- Once the transmission is done, they have stepped down for distribution again.
Apart from changing the voltages:
The substations have a broad spectrum of protective devices.
- fuses and breakers
Their function is to safeguard the distribution networks.
These devices are made in a manner that several distribution circuits could be isolated for :
- load shedding;
Normally, substations are outdoors, and they are covered by a wire fence.
Nonetheless，in high density or residential areas, the substation might be indoors.
Compact substation transformers are commonly found in public with a wire fence in them. Moreover, these are protected inside the building, and the purpose of this is to limit the noise.
3 Major Advantages of Compact Substation
What makes compact substation such a preferred choice over conventional substation is that it is a complete solution that can easily fit into any configuration as per the requirements of the customer.
A Minor Footprint
Compact substations are engineered in a way that they use very little space. And even fitting them in different configurations is not challenging as it is the case with conventional substations. Transporting them to the desired location is easy and there is no need for additional electrical clearances thanks to the covered equipment. They can be installed in areas where traditional transformers cannot, such as in urban settings or in areas with limited space.
Eliminated Environmental Hazards
There is a need for digging the ground for conventional substation that impacts the natural drainage, but it is not the case with a compact substation. As a tamperproof metal container is used to contain the unit, it helps eradicate several environmental threats such as exposed grounding conductors and fencing.
Convenience and Safety
With a compact substation, there are no issues with the relocation of equipment, nor is there a need to destroy or reconstruct a traditional station. This unit is compactly built and its mobility provides utmost convenience. And last but not least, it has safety features such as covered ground conductor, fully contained equipment, built-in oil containment, covered grounded conductors, and very little exposed parts. Overall, it provides a hazard-free environment for everyone around it. We offer compact substation constructed with high-quality materials and are rigorously tested before leaving the factory.
FAQ ABOUT THE COMPACT SUBSTATION TRANSFORMER
- How does compact substation work?
In terms of how substation operations or how a compact substation transformer works, electricity will be produced with a thermal power plant which means that this includes nuclear power plants and hydroelectric power plants.
Electricity is provided to a transmission substation that is close to a generating plant. Transmission substations raise the voltage greatly with the help of step-up transformers.
The electricity that is being supplied to the power station will be stepped down as well with help of step-down transformers.
Moreover, substations will be supplied to a substation grid. There are other voltages and transformers out there that are lowered for the grid. From that point on, the electricity will be supplied by step-down transformers that are close to residential sites.
- Where are Compact Substations Commonly Used?
So where are compact substation transformers commonly used? Basically, they can be used for almost any application. The common applications for compact substation transformers are schools, facilities, streets, subdivisions, construction sites, malls, hospitals, and so on.
- What are the specifications of a compact substation transformer?
Every facility must have specific requirements and needs that must be considered for every customer.
The common safety protectors for compact substation transformers are fuses and circuit breakers. Moreover, they also have load shedding, repairs, lightning arresters, high voltage busbars, and many more. For special requirements, there could be a metering device, low voltage busbar, low voltage circuit breaker, and many more. This depends on the customer’s personal preference.
The specifications of a compact substation transformer may vary depending on the manufacturer and the intended application. Generally, compact substations are designed to be space-saving, versatile and cost-effective solutions for power distribution and control. Here are some common specifications that can be found in a compact substation transformer:
Voltage: Compact substations can be designed to operate at various voltage levels, such as 11kV, 33kV, or 66kV, depending on the requirements of the power distribution network.
Power Rating: The power rating of a compact substation transformer can range from a few kVA to several MVA, depending on the load demand.
Configuration: A compact substation transformer can be configured with various transformers, switchgear, protection devices, and control systems, depending on the application.
Size: The size of a compact substation transformer can vary, depending on the power rating, configuration, and the available space for installation.
Protection: Compact substations are designed to provide safe and reliable power distribution, and they can be equipped with various protection devices, such as fuses, relays, and circuit breakers, to prevent overloading, short circuits, and other faults.
Overall, the specifications of a compact substation transformer should be tailored to meet the specific needs of the power distribution network, while also providing space-saving, cost-effective, and reliable solutions for power distribution and control.
