Electricity, one of the most important inventions of Modern Physics, has a wide range of applications everywhere. In the management of Electric power, transformers play a crucial role, and we can find transformers in every industry, commercial spaces, power plants, sub-stations, etc. Transformers are used for various purposes and it provides a lot of benefits.
Oil-Filled Transformer- Definition
Transformer is an electric device, which can increase or decrease the voltage according to the requirements. Transformers generally work on the principle of Faraday’s electromagnetic induction and there are many types of transformers available nowadays. Some of the popular types of the transformer are like power transformer, step up and step down transformer, dry type transformer, liquid type transformer, isolation transformer, etc.
Oil-filled or Liquid type transformer is one of the popular types of transformers, and in this type of transformer the coils are immersed in the mineral oil. This oil acts as the cooling agent, which helps to maintain the temperature of the transformer under control.
Importance of Maintenance
Maintenance is one of the major aspects to keep the oil-filled transformer in good working condition. Overlooking the maintenance of the transformer will result in issues that can snowball into severe operational problems and system failures.
Coming to the maintenance, staying ahead of equipment concerns will help to address the issue sooner. It means we have to inspect the transformer before it shows warning signs. Since maintenance plays a crucial role to maximize the performance, it would be best to have a professional conduct all inspections of oil-filled transformers.
There are a lot of advantages to having experienced professionals on-site to inspect the performance and condition of the transformer. It will help to spot every potential issue and also to address before becoming severe. Outsourcing the inspection of oil-filled transformers saves a lot of time by avoiding eliminating the need of training in-house employees. Plus, it will reduce the chances of injuries and other on-site, while employees dealing with unfamiliar components and technical issues.

Oil-filled Transformer – Potential Failures
Oil-filled transformers could face a lot of operational problems while working. Understanding these common problems can help to pinpoint the signs of upcoming failures, which ultimately save money and eliminate unexpected downtime.
Let’s see some of the common issues that indicate maintenance of the oil-filled transformer.
Oil Leakage: Oil leakage is one of the biggest concerns of an oil-filled transformer, and oil level must be checked frequently. Any minor leaks or sweating should be repaired as soon as possible to avoid serious problems. Also, increase in acidity and moisture content must be recognized and addressed.
Presence of Sludge: Due to decomposition and polymerization chemical reactions, sludge is formed inside the transformer. The sludge creates solid structures that accumulate in the winding and can result in the failure of the transformer.
Mineral Deposit: Because of oxidation and other chemical reactions, the layer of minerals will be created, which will settle on the surface of various components. This mineral layer affects the efficiency of the cooling system and may lead to overheating of the transformer.
Electrical Failures: Electrical failures are one of the most common causes of failures. Electric failures occur due to the line faults and voltage spikes. Proper inspection has to be done to reduce the chances of electric failures.
These are the most common failures that could occur in the oil-filled transformer.
What Are the Benefits That You Could Expect from Maintenance?
Like any other electrical devices, transformers do need regular maintenance to ensure better performance. By following a maintenance strategy, you will ensure that the operations of your business are running smoothly. Also maintenance reduces the chances of unexpected failures and hazardous working conditions.
Below are some of the most important benefits of maintenance.
- Regular maintenance of the transformer will increase the equipment life expectancy, and reduce the cost of replacement of expensive parts.
- By proper and regular maintenance, the chances of occurring dangerous events like explosions and electric failures can be avoided.
- Maintenance reduces unintended breakdowns and failures. So, it will save a lot of time from being wasted because of failures and operation halting.
- If you maintain your transformer in a good condition, you save a lot of money by avoiding repairs.
Maintenance Checklist
Before performing maintenance procedures for the Oil-filled transformer, it is advisable to have a checklist. Here are some of the basic aspects that you have to check.
- Always make sure that the transformer is de-energized before performing maintenance checkups.
- Check whether the transformer generates abnormal noise and vibration.
- Inspect the presence of dirt, dust, and debris in the transformer components.
- Check the oil level and conduct a temperature check.
- Inspect the machine components thoroughly to ensure all the bolts and hardware components are tight enough.
- Check and address the leaks immediately.
These are the common checklists that you can follow to ensure safety of the transformer and people working around it.
