Transformer Maintenance Service
Transformer Installation, Assembly & Testing
Transformers are essential for keeping power flowing to support our work and lives. Transformers are the most important component in the electrical grid. They transform voltage by stepping it up or stepping it down through magnetic induction within the transformer’s windings. They provide the essential link between two circuits or systems operating at different voltages.
Proper handling and procedures for receiving, assembling, processing, and testing a transformer are crucial for its longevity. Installing and testing the transformer confirms its condition before use and establishes baseline tests for future maintenance and assessments.
Our services include:
- RECEIVING a transformer after transport to a substation site.
- ASSEMBLY and PROCESSING of a transformer at the site.
- TESTING a transformer to verify its suitability for service.
- INTEGRATING the transformer into the power system.
Preventative maintenance of transformers and upkeep from a transformer service company is significant to the reliability and safety of your business and facility. When looking for transformer maintenance companies, choose a reliable partner. Trust RESA Power to be your transformer repair company for onsite transformer repair and maintenance.
Transformers Services
Liquid-filled transformers are more often found in the electrical circuit than dry-type transformers. These transformers are normally more efficient, have a better overload capability, and usually have a longer life expectancy. Insulating fluid fills liquid-filled transformers to cool and quench arcs.
A liquid-filled transformer has many parts and pieces. Gaskets are essential for transformer maintenance, from bushings that insulate conductors and keep fluid in, to radiators and other accessories.
Services include:
- Assembling all of the parts on a new transformer.
- Replacing all the old gaskets on a transformer that may be leaking.
- Replacing parts, painting, and regasketing.
- Disassemble and move to a new location.
- LTC (Load Tap Changer) services.
As transformers age or load increases, high temperatures can cause the insulating fluid to spark, arc, or gather moisture, reducing its protective ability. Regular fluid samples assess fluid quality. Fluid analysis reveals transformer health, detects faulty gasses, and identifies potential winding or component issues.
We offer oil testing and analysis at your site or our Sacramento lab for transformer oil maintenance.

Electrical Transformer Maintenance Services
Transformers age over time. The biggest factor in the life of a transformer is the quality of the paper that insulates the windings. If not properly maintained, this will lead to failure.
A transformer failure can be disastrous and may take months to replace, leaving part of the plant without power. To manage this, we recommend annual fluid analysis and periodic electrical testing of the transformer.
Electrical testing is a series of tests that are performed on the bushings and on the windings of a transformer. Common applications for this service include:
- When a new transformer is delivered (make sure it is ok).
- Annual to track the condition.
- When there are suspected internal problems (from DGA).
- After major service.
Preventive maintenance of transformers can be the difference between a failed and a successful business. Prioritizing transformer testing and maintenance can prevent future issues. RESA Power can assist you in creating a maintenance plan to avoid unexpected downtime and keep operations running smoothly. Get a quote for RESA Power’s transformer maintenance service today.
Transformer Installation
Our service centers specialize in on-site installations and field assembly. Our technicians can install either pad mount or substation power transformers based on your facility’s needs. Our technicians will safely install the transformer following all ANSI/IEEE and NEMA-approved guidelines and regulations.
Transformer Inspection
The primary purpose of preventative maintenance of transformers and inspection is to ensure the life expectancy of your assets. Transformer parts must be strong and work well for safe and efficient operation. At RESA Power, we maintain transformers and help you track their condition with the RESA Transformer Assessment Portal (RESA TAP).
Transformer Dehydration and Reclamation
Transformer Dehydration and Reclamation are supported with the required oil heating system, regardless of the challenge. RESA Power treatment units produce more heat than most equipment, allowing effective removal of sludge and moisture in fewer circulation passes.
Transformer Fluid Maintenance
Each liquid-filled transformer will need to be sampled. To accomplish this, a technician Inspects the transformer looking for problems such as leaks. The technician records gauge readings, like liquid level, temperature, and pressure, and then draws a sample from the transformer. The sample is carefully taken and packaged for the lab.
If the results of the test show a problem, the frequency of testing may change. This service is available at many RESA Power locations and is essential for maintaining your transformers.
Transformer oil maintenance services would include:
- Dehydration and filtration of smaller indoor transformers
- Mineral Oil Services including:
- Dehydration
- Degas
- Vacuum fill for transformers 69kV or larger
- Reclaim (using earth)
The transformer oil lab receives the samples and analysis in a couple of key ways. They typically perform a standard screen test which includes:
- Testing for ppm of dissolved moisture.
- Testing the dielectric or insulating strength.
- Testing for the level of acidity.
- Looking at the color.
- Testing the Interfacial tension of the oil to detect contaminants.
- Testing the power factor to identify contaminants.
- Testing the level of oxidation inhibitor.
There is also the key test of Dissolved Gas Analysis (DGA). This test determines the level and ratio of gasses that the transformer is generating and can determine how the transformer is operating. The DGA will detect any significant problem(s) that a transformer or other liquid-filled apparatus may have.
Routine and Specialized Testing
The Transformer Assessment Portal (TAP) lets you monitor your electrical assets conveniently and consistently, available 24/7. Through TAP, you can track assets, monitor trends, and plan maintenance for transformers and circuit breakers.
RESA Power’s certified technicians and engineers assist with data interpretation, equipment monitoring, and maintenance planning. Conducting regular benchmark acceptance and transformer oil maintenance tests ensures stability and reduces unplanned outages, all following ANSI/IEEE and NEMA standards.
