Transformer oil purification needs to be done as part of routine transformer maintenance. Transformer oil in the system can become contaminated by particles, moisture, oxidation, and other pollutants over time. Transformer oil purification involves the process of filtering and removing contaminants from the oil, maintaining good quality and protecting transformer performance.
In general, after purchasing a new transformer unit, transformer maintenance needs to be carried out in accordance with the manufacturer's recommendations. Usually, the first maintenance is carried out after the first few months or 1 year of use, depending on the manufacturer's guide and the use of the transformer. This maintenance aims to ensure that the transformer functions properly and in optimal condition from the start.
Meanwhile, transformer winding rewinding is generally required when the transformer winding is damaged or failed, such as burning, being exposed to excessive moisture, or experiencing damaged insulation. If the transformer winding does not experience serious problems, rewinding may not be necessary. However, regular monitoring and maintenance on transformer windings, such as vision inspection and isolation testing, remains important to ensure the integrity and performance of transformer windings in the long term.
It is important to refer to the manufacturer's recommendations or consult an expert in terms of maintenance and maintenance of the specific transformer you have, as requirements may vary depending on the type and size of the transformer, the operational environment, and other factors.
