Electrical transformers are critical for industries because they keep the operations up and running. Even a minor flaw in them can result in breakdown and the entire operations may come to a halt. Therefore, you cannot ignore their regular maintenance if you want an optimal performance with minimal chances of breakdown and downtime. Basically, you need to cover both regular maintenance and emergency maintenance. Being on top with regular maintenance is important because it reduces the chances of any emergencies. Here is a checklist for the maintenance of high-voltage transformers that you should follow.
Keep an eye on oil levels
To start with, you need to keep track of the oil levels in the transformer so that it performs optimally. It is important to check the level in the oil cap at least on a monthly basis. If the oil level falls below an optimal limit, the equipment will get damaged. Further, fill the oil up to the correct level if the transformer has oil filling brushing. While checking the oil levels, ensure that the breathing holes in the silica gel are clean. At the same time, check for leakages and get them repaired as well.
Check insulation resistance
Another parameter that forms a crucial part of the maintenance checklist is insulation resistance. You must get it done from a professional at least twice a year. This is done by checking the Megger values and oil values of the system. The measure indicates the health of the overall insulation system of the transformer. It also indicates the presence of contaminants in the oil.
Invest in regular cleaning and painting
Regular cleaning and painting are vital to keeping the transformer in great shape over the years. Additionally, they also ensure the highest levels of performance and efficiency of the transformer. Bill Johnson from Utility Service (https://www.utilityservice.net/) says that transformers need to be completely painted regularly in order to prevent costly damage in the future. While cleaning, ensure that you check the brushings for the signs of cracking.
Inspect for the signs of wear and tear
While it is important to fulfill the regular maintenance requirements of high-voltage transformers, you also need to inspect them often for signs of wear and tear. inspection by a qualified professional helps because you need someone who can detect even the smallest of issues. Timely detection matters a lot because it can save your business from downtime and increased the cost of repairs in the long run.
Invest in asset management planning
Beyond just the regular monitoring and maintenance for the transformers, you need to empower your business with a comprehensive asset management planning strategy. Schedule surveys by experts and have regular inspections to keep the equipment working in great condition. Timely maintenance makes all the difference, so you need to be regular with the checks and action.
High-voltage transformers are complex equipment that requires to be handled by professionals with the right know-how and experience. So it is best to collaborate with a service provider you can trust to keep them up and running at all times.
