Prolonging the lifespan of Transformer Oil With Electrostatic Filtration

Transformer failures are an immense financial burden for the power development industry. The regular price of repairing a failed transformer is roughly $1.6 million dollars, in accordance with a 2003 analysis by the International Association of Engineering Insurers (IMIA). Furthermore, IMIA figures show organizations get rid of an extra $2.1 million on average from business interruption brought on by transformer failures.

About 75 % of high voltage transformer issues are generally associated to oil deterioration. As oil ages and starts oxidizing, contaminants start to surface and eventually bind in concert to create sludge. Routine maintenance and effective oil filtration is important to prevent excess sludge from destryong a transformer’s cellulose insulation system. Due to logistical trouble and the purchase price regarding replacing cellulose insulation, it’s critical to get rid of contaminants from transformer oil before damage can occur.


Mechanical screens and other standard oil cleaning methods have long been successful in the potential to remove larger, debris, and dirt contaminants from lubricating oil systems. Though these techniques are unable to catch the microscopic oil byproducts which are very accountable for the design of varnish as well as triggering transformer failures. Moreover, additional costs are incurred when making use of conventional oil filters, as they must be replaced regularly with the purpose to stop contaminants from building up in the air filter and applying a strain on the operating systems.

Electrostatic oil cleaners work much differently and a lot more effectively compared to traditional cleansing devices. Transformer oil purification system ‘s patented design utilizes gradient force, allowing it to take advantage of the organic cost that each and every contaminant contains to draw them toward oppositely charged collector surfaces. As the engine oil flows easily through the system, the contaminants are takes ou by Kleentek, submicronic particles, dust, dirt and products of oil oxidation, including tars and varnishes. These contaminants are caught on the collector surfaces for easy disposal.

Upon setting up on the Kleentek structure, oil is drawn from the principal container at minimal velocity into the electrostatic collector which continuously removes the submicronic and also huge contaminants from the tank. As the cleaned oil from the tank is circulated in the transformer lubrication system, it will then start to strip away any sludge, varnish as well as other contaminants on the inner surfaces throughout the product. Performance issues relevant to contaminant accumulation on surfaces should dissipate in a few months once electrostatic oil conditioners are in use.

Using an ineffective filtration system may ultimately produce an inoperable transformer, a high priced scenario which is going to result in millions of dollars in repair costs and profits loss. Their use best for avoiding transformer malfunction, early oil failure and also costly downtime of equipment are made by the reputation of electrostatic oil conditioners for taking out oil oxidation, tar and varnish contaminants of all sizes and types.
