Abstract:
Transformers, being among the most expensive equipment in networks, necessitate proper utilization, including regular maintenance and the implementation of life-extension techniques when feasible. The aging process of the transformer oil and cellulose paper insulation system produces by-products such as moisture, acids, and sludge, which contribute to the accelerated degradation of transformer insulation. Consequently, removing these by-products through oil regeneration has the potential to significantly extend the lifespan of transformers. Typically, the oil regeneration process involves the percolation of oil through an adsorbent system, followed by filtration and degasification. Various types of sorbents, such as fuller’s earth, alumina, molecular sieves, and silica-kaolin-sand mixtures, are utilized in the regeneration process. Combining the continuous oil regeneration directly at the transformer with the implementation of an online oil condition monitoring system offers numerous benefits and advantages: the combined solution analyses parameters to detect faults early, enabling proactive maintenance and minimizing transformer failure risks. Accurate oil condition data optimizes maintenance planning, reduces downtime, and enhances operational efficiency. Timely detection of oil degradation and faults avoids costly repairs, extends transformer lifespan, and reduces unplanned outages. The continuous filtration, dehydration, and deacidification of the insulation oil keep the transformer in a peak condition. [1]
