Electrical Test
Maintaining a transformer is essential to ensure its safe and efficient operation,
* Transformer Turns Ratio (TTR) Tests (TTR)
* Winding Resistance Tests
* Impedance Ratio Tests
* Polarity Test
* Power Factor Test
* Insulation Resistance Test
* Partial Discharge Test
Internal Inspection
The internal inspection of an electrical transformer is an evaluation process that involves direct observation and verification of the internal conditions of the transformer. This inspection is carried out by disassembling parts of the transformer to access its internal components and evaluate its condition. Some of the components that are inspected during this process may include the windings, core, contacts, insulators, and cooling systems, among others.
Welding
Welding used in transformer maintenance is typically performed using specific techniques to ensure the structural and electrical integrity of the equipment. Some common types of welding that can be applied in transformer maintenance include:
*Electric arc welding
*Submerged arc welding
*MIG/MAG welding
*TIG welding
Coating applications for transformers
Transformers are machines with a useful life of around 50 years, but their original paint will not last this long.
Painting a transformer is important to extend the life of the equipment and use its full potential. By painting them, we avoid rust and eventual interruptions due to downtime, which can occur and cause great losses for a company.
DGA & Oil Sampling
Oil sampling in electrical transformers is an essential procedure to evaluate the quality and condition of the dielectric oil used for transformer cooling and insulation. This process allows us to detect the presence of contaminants, dissolved gases, humidity or other indicators of deterioration that may affect the performance of the transformer. Oil sampling in electrical transformers is a fundamental practice for preventive maintenance and efficient management of transformers.
Oil purification processes
It is a process used in the maintenance of electrical transformers to remove dissolved gases and other impurities from the dielectric oil used in the transformer. This procedure is important to maintain oil quality and extend transformer life, as dissolved gases can affect the insulating capacity of the oil and increase the risk of transformer failure.
