The role of moisture monitoring in power transformers: Boosting transformer longevity and efficiency
No full textIn this article, we will explore how moisture impacts the operating performance and expected lifespan of transformers. We will show that implementing an effective online monitoring system allows for continuous assessment of the transformer’s condition. Combined with routine testing, it becomes a powerful diagnostic tool enabling anticipation of necessary maintenance operations. This approach is particularly important for power transformers, as they are susceptible to moisture-related issues
Balancing energy, material, and cost factors in distribution transformers: Assessing the impact of potential scenarios for stricter minimum efficiency performance standards
No full textEuropean Union (EU) regulation in the area of ecodesign is evolving to meet the requirements of the Ecodesign for Sustainable Products Regulation (ESPR), which places greater emphasis on the circular economy. This leads to the question of whether the energy performance levels of distribution transformers should be further improved. The answer must take the wider context into account, basing its calculations over the entire lifetime of the units concerned and including the impact on power generation capacity needs. After garnering fresh insights, the International Copper Association has reviewed and fine-tuned its earlier analysis published in the April 2024 edition of Transformers Magazine. The new assessment, comparing a range of scenarios and design strategies, identifies the most favourable options, offering a 5% reduction of no-load losses and a 10% reduction of load losses compared to prevailing values
