Transformer failures are an immense monetary burden for the power generation industry. The regular expense of repairing a failed transformer is roughly $1.6 million dollars, according to a 2003 analysis by the International Association of Engineering Insurers (IMIA). Furthermore, IMIA figures show companies drop an added $2.1 million on average from business interruption caused by transformer failures.
About 75 % of high voltage transformer problems could be associated to oil deterioration. As oil ages and starts to oxidize, contaminants start to appear and eventually bind in concert to form sludge. Routine maintenance and powerful oil filtration is essential to stop extra sludge from ruining a transformer's cellulose insulation system. Due to logistical challenges and the purchase price regarding replacing cellulose insulation, it is critical to get rid of contaminants from transformer oil before damage is able to occur.
Mechanical screens along with other conventional oil cleaning methods have long been helpful in the ability to remove dirt, debris and larger contaminants from lubricating oil systems. although these approaches are not able to catch the microscopic oil byproducts which are very responsible for the generation of varnish and also leading to transformer failures. Furthermore, additional expenses are incurred when using standard oil filters, as they must be replaced frequently in an effort to prevent contaminants from building up within the filter and placing a strain on the operating systems.

Electrostatic oil cleaners work much differently and more efficiently compared to standard cleaning systems. Kleentek's patented design utilizes gradient force, allowing it to make the most of the natural charge that every contaminant has to draw them toward oppositely charged collector surfaces. As the oil flows freely through the system, the contaminants are takes ou by Kleentek, submicronic particles, dust, products and dirt of oil oxidation, including tars and varnishes. These contaminants are caught on the collector surfaces for easy disposal.
Upon assembly on the Kleentek system, engine oil is drawn from the principal tank at lower velocity into the electrostatic collector which in turn constantly removes the submicronic and also bigger contaminants in the reservoir. As the cleaned oil from the reservoir is spread through the transformer lubrication structure, it will then start to strip away any sludge, varnish and also other contaminants on the interior surfaces throughout the product. Performance problems regarding contaminant increase on surfaces should dissipate in a couple of weeks once electrostatic oil conditioners are in use.
Using a bad filtration system could sooner or later lead to an inoperable transformer, a high priced circumstance that is going to result in millions of dollars in repair costs and profits loss. Their use ideal for staying away from transformer malfunction, untimely oil failure as well as costly downtime of equipment are made by the name of electrostatic oil conditioners for removing oil oxidation, tar and varnish contaminants of all sizes and types.
