A power transformer is the most expensive and essential equipment of an electric transformer. Therefore, in order to obtain a high performance and long life of the transformer, several maintenance activities are desired. Not only that, a power transformer also requires various maintenance actions, including measuring and testing different transformer parameters. There are mainly two types of transformer maintenance. We do a group is in the routine basis, and the second group is like when it is required.
That means that to get a smooth performance of a transformer we have to perform some maintenance actions on a regular basis. Another type of transformer maintenance we perform as when required. But if one performs regular maintenance properly, there can be no provision for performing emergency maintenance. Regular checking and maintenance of the transformer is also known as maintenance of the condition. Therefore, by maintaining the proper condition you can avoid emergency maintenance and breakdown. That is why a technical staff should focus primarily on maintaining the condition. As 100% state maintenance causes 0% damage to a computer.
There are many different maintenance actions, which will be performed on a power transformer. Some of them on an annual basis, some of them are monthly, some are quarterly, some are semiannual. These are mainly transformer maintenance actions, which will be performed in intervals of 3 to 4 years.
Monthly basic transformer maintenance
First we must discuss about the action that will be taken on the energy transformer on a monthly basis.
1. The oil level in the oil cap under the silica gel respirator should be checked within one month. If the transformer oil is found inside the cup comes below the specified level, oil to be recharged to the specified level.
2. Breathing holes on the silica gel respirator should also be checked monthly and properly cleaned if necessary, for proper breathing action.
3. If the transformer has an oil filled bush, the oil level of the transformer oil inside the bushing must be checked individually on the oil meter attached to the bushing. This action will also be done monthly.
If necessary, the oil fills in the ferrule to the correct level. Filling of oil to be performed under stop conditions.
