The Significance of Transformers in EV Charging Infrastructure

If the world wants to move away from fuel powered vehicles and adopt electric cars at a large scale, we will need charging stations almost everywhere we see petrol pumps today.

However, it cannot practically happen if there is no stable power supply. This is where transformers come in; they handle tasks like reducing high voltage, distributing power properly and keeping the overall grid stable.

Basically, transformers bring the grid’s high voltage down to a level EV chargers can safely use. 

And as ultra fast charging becomes more common, having a dependable transformer is not optional anymore.

Why Dry Type Transformers Work Perfectly for EV Charging Setups

Dry type transformers are a win-win for EV infrastructure as they use solid insulation instead of liquid insulation oil. Because of this, they are safer in case of fire, easier to install in compact spaces, require very little maintenance and are generally more environmentally friendly.

What Is a Solar Transformer?

A solar transformer is specifically designed for application in solar energy systems. It is used to adjust voltage levels generated by solar panels. It either increases or decreases them based on the end use needs.

However, solar panels produce energy in DC form, which cannot be directly used in homes and industries. It first should be converted into AC through an inverter — an ideal type of electricity for residential and commercial spaces.

Is a Solar Transformer the Same as an Inverter Duty Transformer?

“Inverter duty transformer” is often called a “solar transformer.” This is not completely wrong since it is a type of solar transformer.

But it is important to understand that both are not the same thing. When we say inverter duty transformer, we refer to a type of solar transformer and not the solar transformer itself.

The main purpose of an inverter duty is to manage output from solar inverters, which is subject to change depending on availability of sunlight levels.

Technically, all inverter duty transformers are solar transformers. However, not all solar transformers are inverter duty.

Additionally, some solar transformer types find applications in other parts of a solar setup, such as grid connection or auxiliary power.

Now, let us see where and how these two transformers fulfil their duties.

Inverter Stage: Converting DC to AC

The AC output from the inverter often comes with voltage spikes, harmonic distortion, and frequency variations. At this stage, right after the inverter, inverter duty transformers are placed in the transmission chain.

So, what role do they play?

An inverter duty transformer handles voltage fluctuations, increasing the voltage to transmit power over long distances efficiently. It manages high frequency stresses. And it also filters out harmonics from the inverter output.

Most importantly, it isolates the inverter from the grid to ensure safety.

Solar Transformer Stage: Grid Integration

In large scale solar plants, the solar transformer acts like an ocean and stores the total output of several inverters as if they were rivers.

This main transformer helps maintain compatibility between the solar plant and utility grid. It not only steps up the voltage level to match grid transmission needs, but also reduces energy loss during transmission.

Conclusion

Overall, while inverter duty transformers ensure stable and clean energy flow from the inverter to the main grid, solar transformers perform a similar role at a higher level and connect the entire solar plant to the main power grid.

India’s Rise in the Global Transformer Market

  The manufacturing sector in India has been witnessing exponential growth in recent years. Various industries such as electronics, automobi

[aetrafo-electrical]

Understanding Transformers: Their Working and Key Components

A transformer is an electrical device. It is used to safely transfer electrical energy between two or more circuits through electromagnetic induction. Its main purpose is to regulate voltage levels: raise or lower voltages according to the requirements of the end use. It ensures safe and efficient power supply even over long distances.

The Operating Principle of a Transformer

Ever heard of the electromagnetic induction principle? It was given by Faraday.

The transformer operates based on this principle. According to the principle, upon applying AC voltage to the primary winding, a magnetic field is created in the core. This magnetic flux induces a voltage in the secondary winding, paving the way for the transfer of electrical energy.

Transformer Parts and Their Functions

Buchholz relay: This part of the transformer can be understood as a gatekeeper. It turns on alarms or makes shutdowns as and when it detects the production of gas due to faults inside the transformer.

Pressure relief valve: It helps get rid of excess pressure and prevents explosions, eliminating the possibility of major accidents.

Breather: This one does not allow moisture to enter the transformer oil. It helps maintain integrity of the insulation material.

Cooling system: This cooling system maintains the flow of the oil inside the transformer and circulates it to every corner. It helps keep the transformer's temperature within a safe range. Two types of cooling methods are used depending on the transformer size and type: one is ONAN (Oil Natural Air Natural) and the other is ONAF (Oil Natural Air Forced).

Tap changer: It adjusts output voltage without turning off the transformer.

Proper grounding: Properly done grounding safely guides fault currents into the ground, preventing electric shock and severe damage.

Regular inspection and maintenance: As you regularly check for oil quality, leaks, insulation integrity, transformer components and electrical testing, you can avert minor faults from escalating to expensive ones. Note that scheduled servicing can help prevent severe faults and downtime.

Use of protective equipment: It is essential to use protective equipment to safely carry out installation and maintenance operations, helping avoid electrical shocks and injuries.

At Atlanta Electricals, we manufacture high-performance transformers. We are a leading transformer manufacturing company in the 220 kV Class. If you are looking for a reliable transformer exporter in India, visit us at https://aetrafo.com/.

What is Vapor Phase Drying?

Vapor Phase Drying is a modern drying technique that is used in power transformers and electrical equipment. It is often referred to as VPD for ease.

Transformers are like huge metal boxes, consisting of lots of cellulose-based paper and some wood components.

During manufacturing or over a period of time, the insulation materials tend to absorb water from the air. Also, thermal and electrical stresses cause breakdown of cellulose insulation, adding significant moisture to it.

The presence of moisture and oxygen in the cellulose can rapidly degrade oil and paper, while water in the oil and paper reduces their dielectric strength.

If that water is not removed, it can make the transformer less efficient or even cause problems down the road.

That is where VPD steps in to thoroughly dry out these internal parts.

How Does it Work?

Here is how VPD works and helps in drying transformers:

Heat transfer: The process involves heating a specialized hydrocarbon liquid in a vacuum, which creates a vapor. This vapor then condenses on the cooler surfaces of the core and windings, transferring heat and evaporating moisture.

Moisture removal: Then, the vacuum system extracts the evaporated moisture together with the hydrocarbon vapor, which is subsequently condensed and reused in the process.

Cleaning: The condensed hydrocarbon also acts as a cleaning agent, carrying away dirt and dust that may have accumulated on the components.

Benefits of Vapor Phase Drying

The following are the advantages VPD offers:

Quick results: Thanks to VPD, transformers can be dried out faster. This is possible because the process uses heat transfer through vapor, which allows more rapid moisture removal than traditional drying methods.

Even drying: The vapor goes to every corner, every part dries equally well, leaving no moisture behind that may cause future damage.

Longer lasting equipment: Removing nearly every drop helps transformers maintain their operational efficiency and service life by preserving dielectric strength and reducing breakdown risks.

Speeds up manufacturing: As VPD reduces drying time, it allows companies to produce more units in less time and deliver finished transformers to customers faster.

What is a Surge Arrester?

Surge arresters play a very important role in protecting electrical systems from overvoltage. They also provide protection against transient surges due to lightning or switching operations.

In simple words, a surge arrester is a protective device. It is used to limit surge voltages and divert surge current safely to the ground.

To ensure safety of electrical equipment, they are widely used in high voltage electrical networks.

Key Types of Surge Arresters

Station class arresters: We can find this type of surge arrester in substations. It is used to protect high-voltage equipment like transformers and circuit breakers.

Intermediate class arresters: In the power industry, these arresters find applications in medium voltage networks. They are used in distribution lines.

Distribution class arresters: This class of arresters are also used in medium voltage systems. This range is typically between 1 kV to 36 kV.

Line arresters: To prevent outages caused by lightning, line arresters are installed along transmission and distribution lines.

Secondary arresters: Secondary arresters provide safety to low voltage equipment and systems inside buildings.

Materials Used

Metal oxide varistor (MOV): It is commonly used for its high-energy absorption capability.

Silicon carbide: It has been traditionally used in older arresters. However, now MOV (Zinc Oxide) technology has largely replaced it.

Applications of Surge Arrester

Power generation: In power plants, surge arrester protects transformers and switchgears.

Renewable sources: It safeguards inverters, transformers, and other components in solar and wind farms.

Industrial equipment: In manufacturing plants, it protects sensitive machinery.

Residential and commercial buildings: In residential and commercial infrastructure, it protects appliances and electrical systems.

Why Arresters are Important for Transformer’s Safety?

Surge arresters safeguard transformers from damage caused by extreme voltage load. This device also prevents breakdown of transformer insulation. 

Without surge arresters, lightning strikes or switching surges can severely damage transformers. Worst, these surges can even destroy them.

They ensure reliable operation of transformers. This minimizes costly downtime and maintenance.

What Happens to Retired Transformers?

We do not pay much attention to the lives of machines. Transformers keep humming behind substations or perched on rural poles till their age of retirement. Every year, thousands of transformers retire after fulfilling decades of service. A few of them are also retired due to overload or damage.

So, what happens to these transformers next?

The Shadow Market of Dead Transformers

In India, most retired transformers disappear into an informal maze of scrapyards for the earnings they bring — copper windings, laminated silicon steel, and mineral oil.

However, this practice also involves risks. Not all yards are regulated in our country.

So, if used transformer oil is not handled carefully, it can be highly polluting. It can seep into soil or leak into drains. People may even sell it illegally for reuse in other transformers or mix it with diesel, which is not ideal at all.

The Central Pollution Control Board (CPCB) has often raised concerns over unauthorised recycling of transformer oil, which often lacks environmental compliance.

Meanwhile, the copper is stripped, the steel is sold by weight, and things like insulation, bushings, oil-soaked pressboards are either burned or buried without any documentation.

Limited Adoption of Certified Transformer Dismantling Practices

Some Indian utilities and private industries send these retired transformers to certified dismantlers. These facilities vacuum-extract the oil, recycle or neutralize it, and salvage metals without releasing toxins. They recycle copper and reprocess steel for reuse.

However, while this is an ideal way to dismantle and recycle transformers, it is an expensive process. It involves paperwork, safety rules, and adherence to environmental standards, something not everyone wants to commit to.

At the same time, there is a lack of rewards such as carbon credits, tax benefits, or green certifications to encourage businesses to go for the cleaner option. So, though morally questionable, many choose the easy way out at the cost of the environment.

Why This Matters Now More Than Ever

India’s power sector is expanding rapidly, and millions of new distribution transformers are expected to be added by 2030, according to projections from the Central Electricity Authority (CEA) and other power sector plans.

Many older units from the early liberalization period are reaching the end of their life. Therefore, we need to act responsibly now. The Indian transformer industry requires an environmentally safe retirement ecosystem. 

Just like humans, machines deserve dignity in their final chapter. If you are looking for a reliable transformer exporter, please visit us at https://aetrafo.com/.

High Tension vs Low Tension Cables

An electric cable is a bundle of wires assembled together to transmit electrical energy from point A to B. In this structure, each wire is made of a conductive material such as copper or aluminium which carries electricity.

These cables are available in a wide range of sizes, designs, and voltage capacities, making them suitable for powering residential, commercial, and industrial setups.

While an electric cable transfers electricity, other cables also carry data and video signals. For example, HDBaseT cables are used to transmit data and power a 100-watt light bulb.

HT and LT Cable Categorisation

Cables are classified into two main categories according to voltage: Low Voltage (LV) and High Voltage (HV) cables. Keep in mind, whenever people around you mention low tension (LT) and high tension (HT), they are actually talking only of low and high voltage cables.

Here are some other ways to categorise LT and HT cables:

Rating: In terms of voltage ratings, LT cables handle voltages up to 1100V, whereas HT cables are rated for voltages from 3.3kV up to 33kV.

Armouring: A layer is applied to cables to shield them against mechanical and environmental threats; which is made of either steel wires or strips. It often comes in two shapes - round or flat. While HT cables are always armoured, a few LT cables come without armouring for use in less challenging environments.

Insulation: LT cables are insulated with materials such as polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE), while the majority of high voltage cables have XLPE insulation. These insulation layers protect conductors against external threats.

Conductors: Conductors are made of aluminium or copper; the former is relatively less expensive than the latter.

No. of Cores: LT cables are available in various configurations; single-core, dual-core versions, and can include up to 61 cores. HT cables, on the other hand, use stranded copper or aluminum conductors and are more often than not designed as single-core or three-core cables.

Dry-Type vs. Oil-Filled Transformers

When the decision comes down to dry type or oil-filled transformers, stakes are high – safety, efficiency, and durability are in jeopardy. These two technologies energize our world differently, each having their own methods, capabilities, varying costs and risks.

We discuss in this article the fundamentals of dry-type and oil-filled transformers as well as the differences between the two.

What are Dry-Type Transformers?

The dry-type transformer is a static device. These transformers are enclosed in ventilated cases that allow air to circulate and cool the coils inside. The windings are coated with a special clear liquid to ensure insulation and protection.

It is important to keep in mind that dry-type transformers are only suitable for application up to 35kV due to cooling constraints. Their air cooling system does not provide sufficient cooling conditions to handle heat generated by higher voltage applications.

Four Types of Dry-Type Transformers

For small to medium voltage applications across industries, following transformers are widely used:

Vacuum Pressure Impregnated (VPI) Transformers

Vacuum Pressure Encapsulated (VPE) Transformers

Cast Coil Transformers

Open Wound Transformers

What are Oil Filled Transformers?

Oil filled transformers basically use oil for cooling. They are sometimes also called “Oil-immersed Transformers.”

These transformers are built inside sturdy, welded steel tanks filled with insulating oil. As the transformer runs, the coil and iron core naturally generate heat. Oil absorbs this heat and then passes it along to a cooling system to maintain safe temperature levels.

Due to the flammable nature of oil, to prevent or minimize risks such as leakage or fire, in case something happens, oil filled transformers are usually installed outdoors.

There are two main types of oil-filled transformers:

1-Phase Transformers

3-Phase Transformers

Oil-type transformers have high demand in industries like transmission and distribution lines, and renewable energy generation.

Differences Between Oil-filled & Dry-Types

Cooling Medium: The most obvious difference is the method used for cooling; the dry transformer uses air while oil-filled transformer uses oil to prevent overheating and fire risks.

Recyclability: One benefit of using oil-filled transformers is their recyclability. You can easily recycle its core and reuse it. On the other hand, dry-types transformers do not come with the same level of coil recyclability.

Efficiency: Thanks to their optimal cooling capacity, oil-filled transformers are more energy-efficient; they can handle high voltage loads effectively, whereas dry ones result in higher energy losses.

Maintenance: Dry-type transformers need less maintenance, mostly due to the fact that they do not use oil for cooling, and therefore, the problem of oil degradation does not exist, and consequently, the purification and maintenance requirement is less. They can remain online during minor faults. But oil-filled transformers need frequent checks on the oil and filtration for proper operation.

Cost: Oil-filled transformers are cheaper to operate initially, especially for larger power ratings. Their ability to provide better cooling reduces additional operational cost. Plus, they offer more options for recycling and remanufacturing, reducing long-term expenses too. On the other hand, dry ones are more expensive initially as well as have higher operational costs as they need more energy for cooling.

Location: Oil-filled units are usually placed outdoors due to spill risks, while dry-types are safer indoors – in offices, hospitals, and malls.

[aetrafo-electrical]

Reducing Transformer Losses and Improving Performance

Transformers play a key role in the efficient distribution of power. However, during power transformation, they tend to lose energy, which gradually reduces their performance efficiency.

Therefore, to maintain its high performance efficiency, it is essential to understand the nature of those energy losses.

Types of Transformer Losses

Transformers typically experience two types of losses: Core (Iron loss) and Winding (Copper loss).

Iron Losses

Iron losses take place inside the transformer’s core because of its continuously altering magnetic field.

Hysteresis loss: Because the core material repeatedly changes its magnetic field, some energy is spent on realigning the magnetic domains. So, every time the magnetic field reverses, a transformer loses energy in the form of heat, which is known as hysteresis loss.

Eddy current loss: Eddy loss occurs when the alternating magnetic fields of the core induce circulating currents in the conductive core material, generating heat and adding more energy loss to the core losses.

Cores made of grain-oriented silicon steel or Amorphous material can significantly minimize iron losses. Amorphous cores are relatively more expensive, but are worth it in the long run as they also help reduce the extra power distribution costs due to energy loss.

Copper Losses

Copper wires show resistance to current flowing through the windings, causing copper losses. This energy is lost as heat. 

High-resistance windings cause greater copper losses. So, if you use wires with larger diameters in the windings, they will reduce the resistance faced by current.

Also, the other good alternative would be going for material with lower resistance - like copper.

How to Boost Transformer Efficiency

It is important to keep transformers safe from overheating and insulation failures. This can be done by establishing excellent cooling systems that can handle the heat generated due to energy loss.

Here are two ways to provide proper cooling to transformers:

Air cooling: For dry-type transformers, fans can be used for cooling and improving air flow.

Oil cooling: This method absorbs heat and transfers it into the surrounding by circulating oil around the core and windings.

Solar transformers often include special winding configurations with enhanced cooling systems to minimize both iron and copper losses, enhancing the transformer's efficiency.

The other way to increase transformer efficiency is through regular maintenance:

Oil analysis: Conduct regular oil analysis to monitor the health of the transformer’s insulation and cooling capabilities.

Thermographic scanning: Employ infrared cameras to determine overheating and excessive losses early.
