Prone to increasing and recurrent exposure to increasing voltages and stresses, transformer insulating oils require compatible treatment solutions that complement the transformer’s infrastructure.

Incepted in 1909 and backed by more than century-old expertise, Hering offers a spectrum of solutions for transformer maintenance of which the EOK transformer oil purification product line is one. Hering EOK series ensures that transformer’s insulating fluids function in optimal operating points, thereby asserting high performance of the apparatus.

Supported by German engineering, Hering offers the EOK series which is a benchmark in oil purification and degasification technology which removes most volatile acids. Hering offers purification plants in three series namely EOK Basic, Standard and Professional lines which remove sludge materials and are tailored to specific requirements.

The filtering systems are popular for their robust design, simple operation and easy maintenance system. Other products include oil regeneration system, PCB removal system, transformer drying ovens, waste oil recycling plants, reactivation clay polishing system, adsorbent mineral polishing system and TIDO series online transformer insulation drying and degassing systems and ISODRY series online transformer insulation drying systems.

Hering offers onsite service for plants including those older than 30 years and are available for assistance round the clock throughout the year. They also offer onsite training on customer requests. They also insist quality awareness among its staff which reflects in unbeatable international quality standards.

Transformer oil filtration: all you wanted to know

Transformer oil filtration is a process through which sludge, dissolved moisture and gasses are removed in order to secure the quality and performance of the oil. Transformer oil is susceptible to degradation as time advances since it is exposed to acid, dust and moisture. Filtration and maintenance is important for transformer oil since it not only enhances performance but also ensures safety and ease of operation for the transformer maintenance team.

Transformer oil is also known as insulating oil owing its name to excellent insulating attributes and stability at high temperatures. It stops arcing and corona discharge besides reducing heat of the transformer and thereby acting as a coolant. The transformer oil protects the core and winding of the apparatus and prevents oxidation of the cellulose paper insulation.
