Keeping your transformer in top condition can raise practical questions. From inspection intervals to repair timelines and maintenance planning — we’ve gathered the most common questions to help you stay informed and prepared.
Cast resin (dry-type) transformers require minimal maintenance. Routine visual inspections, dust removal, and checking for signs of overheating or insulation wear are usually sufficient. Unlike oil-filled units, they do not require oil testing or leak monitoring, making them ideal for low-maintenance environments.
The typical lifespan of a transformer ranges from 25 to 40 years, depending on the type, load conditions, maintenance, and operating environment. With proper care and monitoring, such as using systems like Protrafo Insights®, transformers can operate reliably for several decades.
Transformer oil serves two key purposes: insulation and cooling. It insulates internal components to prevent electrical faults and helps dissipate heat generated during operation. High-quality mineral or synthetic oils, such as MIDEL, also enhance fire safety and extend transformer lifespan.
