Transformer preventive maintenance- an activity that rewards The importance of power in our routine life and the hazards of power failure would well explain the importance of transformer preventive maintenance. Transformer maintenance is considered as profit, since it not only cuts the repair costs, but also adds to the efficiency and the produce. Monitoring different aspects of the transformer in appropriate intervals comprise transformer preventive maintenance, whose benefits are abundant. Different aspects of transformer preventive maintenance is conducted daily, monthly, quarterly, half yearly and annual basis. Oil based transformers Transformer oil purification and transformer oil filtration are included in transformer preventive maintenance steps and enhance operations. When the transformer oil acts as an effectual coolant, it ensures the apparatus to with stand stress that occurs due to heavy loading and short circuit. Oil being the popular insulating fluid is scrutinized for presence bi products such as sludge and acid formation, so that the flow is not interrupted. Such bi products result in breakdown, whose consequences are heavy to bear. Transformer oil must be monitored twice a year for impurities, flash point, DDA and resitivity. The electric, chemical and physical attributes of oil are probed to ensure transformer maintenance. The dielectric dissipation attributes contribute to the resistance of transformer in higher temperatures. Monitoring the transformer oil in this regards, saves huge expenses. The moisture content of the transformer oil is included in its chemical characteristics. When cellulose paper insulation absorbs this moisture, insulating properties receive a beating which results in damage of the equipment. When oxygen in the atmosphere comes in contact with the oil, it results in acid formation which results in ageing and transformer failure. In another probability, where tension occurs between water surface and oil, the flash point and
The significance of transformers and its role in power industry needs no introduction. While on duty, transformers not only transmit power, but also ensure safety of the equipment at different voltage levels. The size of the transformers might vary according to their residential and industrial uses, but the importance of transformer maintenance is the same irrespective of its volume. Transformers are maintained in two perspectives namely transformer preventive maintenance and transformer maintenance based on requirement. Be it oil based transformer or dry type, the staff are trained in transformer maintenance appropriately. Oil based transformers In the case of oil transformers, proper installation and operations are ensured. Care is taken not to overlook basic requirements which could grow up to serious damages when let neglected. The staffs are tutored about probability of trouble shooting certain anticipated conditions, which are grouped together as unscheduled maintenance. Visual
