Transformer Maintenance
A power transformer is most costly and essential equipment of an electrical transformer. So for getting high performance and long functional life of the transformer, it is desired to perform various maintenance activities. Not only that, a power transformer also requires various maintenance actions including measurement and testing of different parameters of the transformer. There are mainly two types of transformer maintenance methods. We perform one group is in routine basis, and second group is as when required.
That means for getting smooth performance from a transformer we have to perform some maintenance actions in regular basis.
Some other type of maintenance of transformer we perform as when they are required. But if one performs regular maintenance properly, he may not have any provision of performing emergency maintenance. The regular checking and maintenance of transformer is also known as condition maintenance.
Hence by proper condition maintenance one can avoid emergency and breakdown maintenance. That is why one technical personnel should mainly concentrate on condition maintenance. As 100% condition maintenance causes 0% breakdown of an equipment.
There are many different maintenance action, to be performed on a power transformer. Some of them in yearly basis, some of them are monthly basis, some other are quarterly, some are half-yearly basis. These are mainly transformer maintenance action, which to be performed in 3 to 4 years interval.
- 1).Water Removal: From 50 ppm down to less than 5 ppm in a single pass & down to 3 ppm after two passes
- 2).Gas Removal: From fully saturated with air (10% to 12% by volume) down to less than 0.1% by volume.
- 3).Particulate Matter Removal: 98% of particles over 0.5μm or over 1μm or over 5μm at customers preference
- 4).Dielectric Strength: Improve dielectric strength up to 75-80KV for New oil.
