Condition Monitoring Of Transformer Oil

Testing and analysis of the transformer oil gives us the assessment of oil as well as transformer condition in it’s running state, enabling us to take better preventive actions and avoid failures / breakdowns. We are India’s leading NABL accredited private laboratory in transformer oil testing as per IEC / IS / ASTM. We also provide emergency on site transformer oil testing services with our NABL accredited Mobile Lab

Transformer Mineral Insulating Oil Condition

Oil and other insulating liquids suffer from electrical and mechanical stresses while a transformer is in operation. In addition there are contaminations caused due to chemical interactions with windings and other solid insulations, catalyzed by high operating temperature. As a result the original chemical properties of transformer oil changes gradually, rendering it ineffective for its intended purpose after many years.

Hence this oil has to be periodically tested to ascertain its basic electrical properties, and make sure it is suitable for further use or initiate necessary actions like filtration/regeneration. Transformer Oil is not only subject to its own degradation, but is also a carrier of gasses emanated during arcing or flashovers between paper and winding insulations.

Transformer Oil Testing and Analysis provides important information regarding any such incipient faults, without the need to pull down the equipment from its running condition. We are India’s leading private laboratory for Transformer Oil testing as per IEC 17025:2000

Transformer Oil Testing Advanced Laboratory ( TOTAL )

Power Electronical NABL Accredited Stationary Oil Testing Lab

At Power Electronical’s Transformer Oil Testing Advanced Laboratory (TOTAL) we are committed to adhere and practice international systems for quality management and Oil Testing & Analysis. We have valid accreditations for ISO/IEC 17025:2005 from NABL and ISO9000:2000. Both the accreditations allows our customers to be able to compare and use the test readings and our analysis to a scale comparable with National test laboratories. It is also a proof of our unswerving commitment to highest levels of quality standards for Oil testing.

Transformer Condition Monitoring Services

Oil Testing is only half the work done. Without correct and accurate analysis, it serves no worthwhile purpose. Our engineers and laboratory staff are well equipped with knowledge and experience to be able to analyze the results and predict any kind of rapid degradation of Oil parameters, or advise residual life expectancy or fault interpretation. We follow it up with site visit and testing of other parameters of your equipment, to confirm the assessment, and help the customer take preventive and corrective measures well within time. A maintenance contract signed with us for all your critical HV/EHV equipment gives you complete peace of mind, because we look after them 24X7 thereafter, including scheduled and emergency visits.
