Compact transformer, also known as prefabricated substation, is a kind of indoor and outdoor compact distribution equipment. It combines the high voltage switch equipment, distribution transformers and low voltage power distribution equipment together in a certain wiring schemes, installed in a steel structure which is moisture, rust, dust, rat, fire prevention, guard against theft, thermal insulation, fully enclosed and movable. It is suitable for mines, factories, oil and gas fields and wind power stations. It replaces the original civil distribution house and power station and becomes a new complete set of transformer and distribution equipment.
Benefits of Compact Transformer
The space occupied is small
Compared with the traditional transformer, the box type transformer installs the high voltage distribution equipment into a sealed steel structure box by scientific and reasonable means. Its internal structure is very compact, and the gap between each component is quite small. Therefore, the space occupied by box transformer is relatively small.
The operation method is very simple, convenient and convenient for quick assembly
Through understanding the construction requirements of power engineering, special designers can make simple and convenient operation of the main wiring and supporting equipment outside the box according to different requirements, so as to facilitate the rapid assembly.
High application income
From the perspective of the cost of creation, we can clearly see that the cost of box transformer is usually between 300000 and 500000. From the operating cost, it can be seen that even under the full load operation state, the box type transformer consumes about 1 million degrees less electricity than the ordinary transformer every year, even if there is a problem, the maintenance cost is less. Therefore, the box transformer has a high application income.
Flexible combination
Because of the characteristics of compact and simple structure, each single transformer is an independent system, which makes the box transformer have a strong flexibility in combination.
The operation is safe and stable
Because the case of box type transformer adopts metal conductor with strong anti-corrosion ability, and the interface between internal equipment and equipment is also insulation material. Air conditioning and moisture removal equipment are set in the box, which greatly improves the resistance of box transformer to the external environment and improves the safety and reliability of its operation.

Combined pad mounted substation
Combined pad mounted substation, also known as American type substation, has transformer main body, high-voltage load switch, fuse, ect in the transformer tank so that the volume of entire substation can be as small as possible.
One of the biggest advantages of compact transformers is that they are useful in many different situations and setups. These substations are helpful in rural and urban settings. It’s also easy to manufacture to your exact specifications, which is helpful if you have a unique setup that may not work with a traditional substation.
Compact transformers are suitable for use in industrial, commercial and residential locations. They are suitable for factories, mines, construction zones and more. Rural neighborhoods and businesses may also find prefab substations suit their needs better than conventional substations.
Construction sites may opt for a compact transformer as they can easily move between sites. Some industries with a substation may purchase a compact system as a backup. Because compact transformers are so easy to take down and reassemble, they are often used as backup power when a conventional substation is undergoing maintenance and repairs.
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.
Compact substation transformers may be small but this type of substation consists of a total set of power distribution equipment that is composed of a voltage control device and a transformer.
The idea is actually quite simple, which is to operate substantial assembly that is rooted on the preferred sequence of the armoring line, pressure starting system, substation automatic system, etc.
A typical transformer has a build that is completely closed with a tempered cabinet structure. Nowadays, compact substation transformers are now widely used in power engineering construction.
Components of Compact Transformer
Incoming high-voltage section
This section is responsible for receiving high-voltage power from the transmission grid. It includes a high-voltage circuit breaker, disconnect switches, and lightning arrestors. The circuit breaker serves as a protective device that can interrupt the flow of current during fault conditions, while disconnect switches enable safe isolation of the substation during maintenance or emergencies.
Power transformers
Power transformers are one of the key components in a compact substation. They step down the high-voltage electricity received from the grid to lower voltage levels suitable for distribution. The transformer comprises primary and secondary windings, and the ratio between the number of turns in these windings determines the voltage transformation.
Low-voltage section
This section of the compact substation includes low-voltage switchgear, which distributes the electricity to various feeders and consumers. It comprises low-voltage circuit breakers, fuses, and other protection devices to safeguard the distribution network from overloads and short circuits.
LV and HV busbars
Busbars are conductive bars or rails that carry electrical current within the substation. Low-voltage (LV) busbars distribute power at lower voltage levels within the substation, while high-voltage (HV) busbars handle the incoming high-voltage power and distribute it to the transformers.
Control and protection system
The control and protection system is the brain of the compact substation. It consists of various relays, sensors, and monitoring devices that continuously supervise the substation's health and performance. The system detects faults, abnormal conditions, and operates the necessary protective devices to ensure the safety and reliability of the substation.
How to Maintain Compact Transformer
To ensure your transformer operates smoothly and avoids breakdowns, it is crucial to conduct thorough inspections. Before installation, carefully examine the transformer for any signs of trouble. Look out for burnt odours, damaged power cords, improperly installed parts, or any other abnormalities hindering its performance.
When working on a transformer, prioritise safety by ensuring the power is switched off. This precautionary measure is essential to prevent electrical leakage or any continuity between the current source and the system. Always double-check to confirm that no power flows through the transformer before initiating maintenance or repair tasks.
It is essential to use protective equipment when working with transformers. Use appropriate gear such as gloves, goggles, and other safety attire to safeguard yourself from potential hazards. Additionally, pay close attention to the specific voltage ratings of the transformer. Ensure that over current protection of conductors and circuits is set according to the manufacturer’s standards to maintain a safe operational environment.
Familiarise yourself with the maximum voltage requirements of your transformer. Avoiding system overload from a single transformer that is handling excessive load is crucial. Consider using multiple transformers to balance the impedance of each load and distribute the electrical load more effectively. This helps optimise the performance and longevity of your transformer system.
Maintaining a clean and organised work area is essential to prevent accidents and protect the transformer. Ensure that spare nuts, bolts, and other objects are kept away from the work zone. The risk of these objects falling into or inadvertently contacting the transformer can be eliminated by maintaining a clutter-free and well-organised workspace.
Ensure your transformer is properly grounded to prevent static electricity buildup and protect the coils from contacting the enclosure or core. Proper grounding is a crucial safety measure that helps minimise electrical risks and maintains a stable operating environment. Grounding reduces the accumulation of static charges and safeguards the windings from contacting the core or enclosures.
Moisture or water can cause severe damage to transformers and compromise their performance. Always keep your transformer and its components dry and free from moisture or water. Additionally, to ensure the safety of unskilled onlookers, set up caution signs in the vicinity. These signs effectively warn people about potential dangers and instruct them to keep a safe distance from the transformer. This, in turn, contributes to the overall safety of the workplace.
If any irregularity or abnormality is observed in the transformer’s functioning, promptly shut it off and unplug all cables and power cords before conducting a thorough analysis. This analysis allows for a focused examination of the specific part or component experiencing issues. By identifying the underlying problem, you can implement targeted solutions and minimise downtime, optimising the transformer’s performance and reliability.
Before undertaking any maintenance work, it is imperative to de-energize and shut down the transformer and its associated circuits. This vital safety precaution eliminates the risk of current leakage or continuity between the power source and the system. De-energizing the equipment and appropriately tagging it out protects personnel from electrical hazards and ensures the integrity of the maintenance process.
To safeguard your transformer and ensure proper maintenance, it is imperative to restrict maintenance tasks to qualified personnel. By setting up caution signage, you establish clear visual cues that indicate the need for expertise in handling maintenance activities. This measure helps prevent unqualified individuals from performing tasks that may pose risks to themselves and the equipment. By entrusting maintenance to qualified personnel, you can have confidence in the quality and safety of the work.
