We all know what a transformer is, how it works, and how to use transformer oil.So, in this post, we’ll talk about how crucial it is to handle transformer oil properly, produce it on schedule, and use current techniques to extend the life of the transformer. Here, you can see what can occur if the oil type transformer ageing process is ignored.
Oil analysis- Main Types
- Dissolved Gas Analysis
DGA (Dissolved Gas Analysis) allows us to identify issues that are progressively escalating in a transformer.
The ability to analyse potential issues and anticipate the service life of the transformer is made feasible by the increase in gas concentration over time.
Using dissolved gas analysis, the following issues can be located:
- Partial discharge and discharges
- formation of contact layer alien layers
- abnormal cellulose deterioration
- localised metal component overheating
- Appearance and colour
Although look and colour are not fundamental characteristics or requirements for action, they do aid in comparative evaluation:
Oil that quickly darkens or turns dark signals that it is getting older. Sedimentation in the oil starts even when the colour shifts from 2 to 3 on the colour scale.
- Breakdown Voltage
Breakdown voltage is essential for maintaining the transformer since it shows how well the insulating oil can handle the electrical load. The breakdown voltage thresholds for each type of transformer are different.
- Water
Due to improper maintenance of air dryers or flaws in the sealing system, water might occur during the ageing process of cellulose, an insulating material, as well as to a lesser extent during the ageing of oil and primarily during the process of absorbing atmospheric moisture.
Although there is a desiccant upstream, water is generated even in the expansion tank; these values have not before been assessed. The transformer’s temperature changes are to blame for this. Water in solid insulation and water in oil are in equilibrium, which lowers breakdown voltage and speeds up ageing. However, both time and temperature affect this equilibrium.
Temperature, humidity, and oxygen are the main factors in transformer ageing and failure.
Effects of humidity and temperature
Temperature, oxygen content, and water alone all have a significant impact on how quickly things age. High temperatures and water concentrations in transformers can speed up ageing by a factor of 20.
Anti- ageing actions:
- Regular trend analysis of dissolved gas analysis and oil index determination
- Drying reduces moisture
- Using degassing when the oil has a high gas concentration
- Changing the oil
Tips For Long Life Of Transformers
A transformer is the best option when you want to convert the alternative current and move electricity efficiently from one circuit to another. It comes in a variety of designs, ratings, capacities, and other parameters. Vajra Transpower, one of the Best Transformer Manufacturers in Hyderabad, strives to give attention to each person and tailor the solution to suit their tastes. We adhere to strict industry standards and do everything in our power to maximise client satisfaction. But always remember that we are responsible for our own safety. If you are aware of this information, it will greatly benefit you in protecting your devices from harm and extending their lifespan. Here are some safety tips that you must adhere to when using transformers.
Keep Monitoring Your Device:
The easiest approach to prevent your device is to constantly monitor how it functions. You may help to keep your gadget safe by checking for cracks, burning odours, and inappropriate power plugs. And you are aware that the device’s safety comes first.
Not To Put Extra Load On Device:
Each device has a maximum load that should not be exceeded in this situation due to an increased risk of damage. This will allow your transformer to operate for a longer period of time because it won’t place an additional stress on your gadget.
Install Your Device In Right Environment:
Always set up your gadget in the proper setting. You can keep your gadget safe and secure by doing this. Installing the gadget should be done away from any water. Water raises the possibility of a short circuit.
Everyone should bear in mind these essential hacks to ensure the secure and efficient operation of their equipment. Trust in us if you’re looking for a transformer of the highest calibre.
