Transformer, one of the important devices, which has a wide range of applications in Industries, commercial places, power plants, and many other places. Transformer is one of the inevitable parts of a power management system.
A transformer is an electrical device which can alter the AC voltage by maintaining the frequency of the current. Transformers work on the principle of Faraday’s law of electromagnetic induction, which describes how a magnetic field will combine with an electrical circuit to produce electromotive force (EMF).
There are two main aspects that need extra care, one is the process of selecting the transformer, and the other is its maintenance. A slight negligence in any of these aspects could create a lot of trouble in the long run.
Why is Inspection of a Transformer Important?
Like other electrical equipment, transformers also need regular maintenance to keep it running smooth and safe. Depending on the type of transformer, its operational conditions, and other factors, transformers need scheduled routine inspection to identify, troubleshoot, and solve major and minor problems before they arise.
Keeping the transformers in the right condition also helps to prevent the chances of power failures or accidents, shocks, and other severe accidents.
Signs Your Transformer Need Inspection
There are many types of transformers, and oil cooled transformers are one of the popular and most used transformer types. Here are some common signs that you can experience when your transformer is damaged.
- Change in the operational temperature of transformer
- Low insulation resistance
- Show high earth voltage of the transformer
- You may experience unsymmetrical voltage on the secondary side
- Transformer may sometime create a lot of noise than usual
- Sometimes even smoke starts coming out of the transformer
These are some of the signs which you can experience if your transformer needs repair or replacement.
Standard Test to Determine Errors in Transformer
There are many tests that you can use to determine errors in your transformer. There are also some tests that do not need costly equipment. Let’s see some of the key tests, which you can use to determine the condition of the transformer.
- Noise & Vibrations
Almost every device that works on electricity would make noise, but the intensity of noise is very low. Mostly dry type transformers make more noise, but if you are using an oil type transformer, it makes a lot more sound than usual, then it needs proper analysis.
- Leaks and Errors
Leaks in the oil or errors in the working process of a transformer are common problems, but they should not happen too often. Regular oil leaks, and errors or repairs of transformers is a sign that it needs a replacement.
Putting a lot of money consistently on repairs, it would be better to purchase a new one. It will save a lot of money, and also helps to prevent major or minor accidents while working.
- Dissolved Gases Test
While a transformer is working, a lot of gases are released because of the breakdown of its material. Dissolved gases tests help to reveal the type of gases that is being released by the transformer while working. In this test, the oil will be tested to find the gases that are being released.
This test could give many valuable insights of a transformer, and depending on the test results, you can choose further action.
How Regular Maintenance Help?
Regular Comprehensive transformer is very important and it could help to prevent further problems in the future. For the health and safety of the equipment and people, it is imperative to take maintenance regularly.
Every Industry must maintain a proper schedule for inspection of transformers, to increase the efficiency of the transformer. This also helps to reduce interruptions in the work because of power breakdowns.
The inspection results could help you to analyse the condition of the transformer and based on the results you can repair or purchase a new transformer.
