Transformer Repair Services We Offer

Upgrade – KVA

Electricity is a necessity in today’s world. It provides energy to our homes, businesses, and critical infrastructure. It is critical for a functioning society to ensure that the appropriate amount of electricity is delivered to where it is required. That is why transformers are so essential. A transformer is a device that aids in the regulation and management of electrical current. They come in all shapes and sizes, but the 250 KVA transformer is one of the most common.
If you need to install or upgrade a 250KVA transformer, Grant has this type of transformer available. The company has established itself as one of the top manufacturers of high-quality transformers because its products adhere to international standards such as ANSI, IEEE, IEC, CSA, and AS/NZ.

Upgrade – Voltage

Grant Transformer is dedicated to assisting our customers in the maintenance and management of their high-voltage infrastructure.
We have the accreditations and experience to ensure the safe and optimal operation of your electrical assets, from high voltage compliance audits and safety management plans for repairs, maintenance, upgrades, and testing.
Grant’s 24/7 high voltage service technicians and electrical engineers are critical to meeting our commitments because they provide support to ensure your high voltage systems are compliant and running at peak performance.

Oil Servicing and Purification

If oil needs to be removed from the site, we can arrange for the removal and transportation of oil and associated materials, including oil contaminated with PCBs. 
In addition, we retrofill transformers with mineral or natural ester fluids. 
With oil contamination being the leading cause of insulation breakdown and transformer failure, it’s critical to keep your transformer oil in good condition. At Grant, we streamline and filter your oil to reduce contaminants and impurities, as well as separate moisture and gases, to help your transformer’s effectiveness and reliability. 

Liquid Filled or PCB Replacement

Grant Transformer is committed to voluntarily reducing polychlorinated biphenyls (PCBs) by replacing PCB-contaminated transformers with non-PCB oil-filled equipment.
Efforts have been made throughout our system to remove or replace PCB-contaminated transformers, and we will continue to evaluate and reduce the amount of PCB-filled equipment in our system.

Upgrade – Efficiency

Transformers are efficient machines that aid in the safety and efficiency of a power system by controlling the rise and fall of voltage levels as needed. Because the transformer acts as a conduit for the smooth passage of electricity, even minor improvements in transformer efficiency can result in significant electricity savings. As the number of residential and industrial applications grows, transformers play an increasingly important role in the distribution and regulation of power over long distances.


Core and Coil Back-Up

We analyse our customers’ industrial equipment to determine the cause of failure and redesign or re-manufacture transformers and speciality coils to extend their useful life as part of our industrial maintenance services. We use only the best materials and workmanship to exceed industry standards, whether it is a simple overhaul, rewind, or core replacement. Grant is not only capable of assessing your requirements, but we are also capable of providing the highest quality solutions to maximise your productive uptime and reduce operating expenses.

Painting/Shot Blasting

Surface preparation has a significant impact on the performance and durability of any paint coating. This is especially true for steel structures, where the method of surface preparation chosen is critical in any corrosion treatment.
Power and distribution transformers are the most expensive components of energy transmission lines, as is well known. With proper maintenance, these components, particularly those of the cooling system, can operate efficiently during the scheduled times. We choose the best painting method and materials based on customer preferences and our painting facility’s recommendations, and we produce 100% coated anti-corrosion surfaces.

Step Voltage Regulators

A step voltage regulator helps to prevent poor-quality signals from being sent to users over distribution lines. Step voltage regulators are primarily used in utility distribution applications to distribute electrical signals to properties. It allows users to receive a much more dependable power signal, even in high-demand areas where the incoming signal may become unstable due to the number of consumers drawing on it.
Voltage regulators are an important part of a distribution system because they help regulate voltage as loads change. This is critical because it prevents voltage in electrical equipment from becoming too high during power fluctuations, thereby preventing problems such as blackouts and power outages.
Grant Transformers has years of combined industry experience, allowing us to repair or replace your voltage regulator with a higher-quality part. With an industry-leading inventory of equipment, we can provide customers with custom-made parts in a variety of applications on time.


Transformer testing is done to confirm the specifications and performance of an electrical power transformer. Because the transformer is the most important component of an electrical distribution system, its failure will have an impact on the entire system. As a result, it must go through a number of testing procedures. Grant performs some of the tests before delivering it to the customer, and also while repairing them. Transformer testing is required to ensure that the transformer is working properly and to reduce the likelihood of failure. All electrical equipment must be maintained safely from some failures. Failure of a transformer can be caused by electrical, thermal, or mechanical factors. Transformer failure will also result from insulation failure.



Reasons To Choose Our Transformer Repairing Services

Transformers play an important role in our daily lives. They provide the electricity required to power our homes and offices’ lights, air conditioning, appliances, and technology. A transformer failure or malfunction can cause significant disruption and inconvenience. Fortunately, we can rely on Grant transformer repair services for quick and dependable results to help restore power as soon as possible.

Indications of a problem 

One of the most obvious signs of a problem is when your transformer stops working entirely. This could indicate a power outage, or it could indicate a problem with the transformer itself. Repairs to high voltage circuit breakers, buzzing or humming sounds from inside the transformer, and flickering lights are also signs.
