Monitoring Distribution Transformer

2019-09-01

Use of distribution transformer in Nepal is very popular and it is used all over the country to transfer electric power to homes and offices i.e. distribution transformers are responsible for getting the power to the end lines or end users. By using the step down method, distribution transformer reduces the high grid voltage that is received from power transformers to user required voltage. These transformers are also designed and built to work in an efficient manner as a distribution transformer generally will be working all day long.

Proper monitoring of distribution transformers should be done in order make sure they are working properly or not. These electric machines should be checked from time to time so that the operators can know if any maintenance tasks can be carried out. By carrying out timely inspections, distribution transformers can be kept in tip-top working condition and any potential bugs and errors can also be found and solved before any damages are caused.

Before, monitoring of distribution transformers weren’t done properly once they were installed. However today, utility companies are aware about the importance of proper monitoring and use various modern monitoring techniques to ensure that the distribution transformer is working alright. Many utility companies now have started to use smart metering solutions to monitor the distribution transformers.

Automation of distribution substations helps in improving the visibility of low voltage networks and also helps in utilizing the power in the best way possible. The initial step of distribution automation is monitoring itself. Hence, monitoring is essential for from the point of automation too. Not only that, but monitoring of distribution transformers can benefit us in multiple ways. Here are some ways in which monitoring of distribution transformers can benefit us

Find Weaknesses

One of the most prominent benefits of monitoring is to recognize when any part of the machine is on the brink of being damaged. By conducting timely monitoring, operators will be able find out about the bugs, examine them and take timely remedial actions and prevent any damage to the system. It is often the case that we see a lot of distribution transformer damages simply due to the lack of monitoring and by not knowing about the condition of how the installed transformers are working.

Improve Visibility Of Low Voltage

Through monitoring of distribution transformer, we can get improved visibility of low voltage power networks. This will help the utility and power companies to deliver high quality electricity to their customers. When the visibility improves, the system will be able to provide real time information about voltage, power factor, current, harmonics and any unbalances from the LV network. When operators get these useful information, they can be aware and take specific measures to prevent bugs and even solve problems more easily as they occur.

Reduce Power Outage

The problem of power cuts and power outages is a common one that has been haunting Nepali people are facing for a long period of time. We may be aware of the fact that power outages occur mainly due to the lack of proper infrastructure or may be due to lack of water. However, we may not be aware of the fact that more often than not, power cuts also happen due to damages or errors in the distribution transformer installed in the respective areas.

Don’t we often hear a big bang and all of a sudden the only thing around us is pitch black darkness? This is caused mostly due to the damage that occurred in the transformer powering the area around us. Also, more annoying this is that when a distribution transformer is damaged, the power outage time is considerably a lot more than is other cases. Sometimes, due to damage in distribution transformer, power may not even be back for days and ultimately, civilians and local businesses suffer. This problem can hugely be eliminated by performing the simple task of monitoring and checking.

If distribution automation techniques can be properly implemented in the distribution transformer systems in Nepal then this can help a lot in reducing unexpected transformer failures which results in power failure. It is because automation systems can recognize the outgoing LV feeder outages or problems and instantly send signal or warning to the operators. With information that is received through automation, the utility companies can get vital data about overloaded transformers and can prevent them from being damaged by taking timely measures and precautions.

Make Proper Decisions After Monitoring

Of course the information obtained from monitoring process is crucial. However, we shouldn’t forget that the actions we take after we get the monitored results is just as critical. The operators should be able to make efficient decisions and plans to make sure the distribution transformer systems are working in top condition without any loose ends. After getting the data, swift decisions and plans need to be made about things such as setting up critical points and doing upgrades and updates in the network where it is needed.

For example, when operators get the idea that a distribution transformer is performing with more than 75-80% of its average capacity, then they will have a clear idea about which part of the system needs extension or upgrades and act accordingly. In similar manner, the utility companies can also benefit from monitoring as they will be able to manage the assets and resources in a proper and effective manner.

Measure And Solve Energy Losses

Energy losses are also a key factor behind why Nepalese people, businesses and economy suffers so much from lack of power. Smart meters should be installed with all the customers sharing the network then LV network losses can be calculated. Also, the weak points can be found out through thorough monitoring which will help to develop a strategy which will tackle energy losses.

With all these benefits that can be gained from monitoring distribution transformers, why not try it and see the differences for ourselves?
