Transformer Repair

3L2R’s transformer repair services offer a technically sustainable and financially attractive solution that meets the highest environmental standards in the electrical supply industry. Our transformer repair services result in a transformer that operates at peak performance. With our engineering knowledge and vast practical experience, we are ready to assist you in acquiring a transformer repair solution that will best benefit your business. Because transformers are expensive items that are an integral component of an organizations process, it’s important that they provide continual, reliable operation. The average transformer has a lifespan of 25-30 years; it’s a given that it’s components and structure will eventually be unable to tolerate the stresses imposed on it during its operation. Many factors can contribute to transformer failure, resulting in costly expenditures to replace, and a slow-down or complete shut-down of a company’s activities. The typical failures that occur in a transformer as a result of these stresses include, but are not limited to:

• System switching operation failure
• Winding failure
• Busing failure
• Tank failure
• Protection system failure
• Cooling system failure
• Insulation failure
• Tap changer failure
• Core failure

The stresses that a transformer experiences during its normal and transient operating conditions fall into three categories:

• Electrically promoted stresses resulting in a reduction in dielectric strength, decreasing the transformers capability to withstand electrical stresses, and causing damage to the transformers insulation system.
• Mechanically promoted stresses resulting in a reduction in mechanical strength, lowering the transformers SC withstand capability, and causing deformation of the transformers windings.
• Thermally promoted stresses resulting in a reduction in thermal integrity of the current carrying parts, reducing the transformers ability to withstand the overload conditions, and causing damage to the transformers cooling system or oil pumps.

These stresses can also cause overheating, impair oxygen supplies, create excess moisture buildup, contaminate insulating oil, cause partial discharge, and be the source of system overload or short circuiting. Regardless of the types of stresses a transformer endures and the failures that result, transformer demise can be a major set-back for its owner / operator. To combat these issues, 3L2R offers transformer repair services that are economically and technically efficient, restoring transformers to their original condition in respects to voltage, current, and impedance. Our transformer repair services are a cost-effective solution to the expensive and lengthy process of acquiring and installing a new transformer. Our transformer repair services are considered the very best in the electrical supply industry. Our transformer repair professionals provide transformer repair services that will effectively:

• Avoid future bottlenecks in new transformer availability
• Increase the existing capacity of your transformer
• Adapt your transformer to new grid conditions
• Extend the life of your aging transformers
• Eliminate high replacement costs
• Create faster turnaround than purchasing a new transformer

3L2R is capable of repairing transformers from all manufacturers and performance classes, including:

• Padmount transformers
• Polemount transformers
• Dry type transformers
• Step-up transformers
• Low, medium and high voltage transformers
• Single-phase transformers
• Three-phase transformers
• Power transformers
• Current transformers (CTS)
• Silicone and ester fluid filled transformers
• Core form transformers
• Shell type transformers
• Step-down transformers
• Station type transformers
• Oil type transformers
• Potential transformers (PTS)

You could trust 3L2R to sell you a new, fully functioning transformer, but why go to great lengths and expenses when you can successfully rectify the problems instead with our transformer repair services? 3L2R’s transformer repair process can be conducted on or off site, and incorporates three phases so as to ensure that your transformer is repaired accurately, within budget, and on time:

Transformer testing, evaluation and life cycle assessment

How is your transformer really performing? 3L2R’s on-site diagnostic methods makes it possible to determine your transformers current condition and life span with high precision, so as to successfully classify its current and future operational reliability. Our comprehensive testing, evaluation and life cycle assessment is available on three levels: essential level diagnostics which are performed during standard operation, advanced level diagnostics which require minimum outages, and optimal level diagnostics which integrate high-voltage testing to evaluate the operational condition and residual life span of your transformer.

Transformer failure investigation

A complete transformer failure analysis, including inspection of it’s electrical controls, will be conducted on-site to determine its root cause of failure. We will provide you with an in-depth transformer repair analysis report, and discuss transformer repair versus transformer replacement recommendations with you so that you can make the best economic decision for your organization. 3L2R will be able to give you an estimate time frame of delivery upon completion of its repair.

Transformer redesign and reconfiguration

Upon agreement of the actions to be taken, your transformer will be un-tanked, transported and inspected at our transformer repair facility. Active and noble parts like, bushings, cores, housing, windings, insulations accessories and other auxiliary equipment will be serviced, retrofitted or upgraded. Then once an acceptance test is performed to ensure your newly repaired transformer is ready to be re-energized, we will then be able to promptly transport your transformer back to you and ensure it is placed and ready for service.

3L2R's goal is to provide 100% satisfaction; that is why we take care of all the logistics and special permits for your transformer's dismantling, handling, restoration, assembly and installation. Our facility complies with all the requirements of electrical services and product standards, as well as each our clients unique industry specifications.
