How To Ensure High Performance Of Electrical Transformers?

The efficiency of utility maintenance programs is essential for seamless transportation of power to the consumers. Proper coating and regular cleaning can go a long way to improve power transmission and reduce intermittent failures and complete blackouts. It can also reduce the need for costly repairs, thus ensuring higher durability of the transformers.

How To Ensure High Performance Of Electrical Transformers? 

Electrical Transformers

Constant monitoring, cleaning, and painting the transformers can increase productivity by leaps and bounds. In this post, you are going to know more about the key reasons for upgrading your maintenance program along with the right measures to protect the transformers, thus ensuring maximum convenience for the customers. 

Preventing contamination

The high-voltage insulators should be routinely monitored and cleaned to prevent contamination, which may lead to power failures. Upgrading the maintenance program will ensure the efficiency of the substations, especially the ones that still use old transformers. 

The steel structures are not immune to corrosion

One of the common myths about advanced steel structures is that they don’t corrode. This is one of the main reasons for not employing regular inspections of the electrical transformers. However, the studies have proven that transformers can develop rust, which affects proper functioning. 

They are also subjected to constant weathering, which may lead to permanent failures, if not maintained regularly. The experts at  feel that a coat of paint on these transformers can increase their lifespan to a great extent. They will prevent corrosion and weathering, thus improving the efficiency of the substation for years to come. 

Cleaning the transformer before applying paint

Before you paint any electrical surface, you should make sure that it’s thoroughly cleaned. It should be free from loose paint residue, chalk, flake, dust, oil, and every other impurity that may affect its performance. Opt for an experienced team of professionals, who use advanced equipment like grinders and pressure washers to reach the bare metal. 

Preparing the transformer for painting 

After cleaning the transformer, the insulators and gauges along with other sensitive equipment should be properly covered to prevent over-spraying. The fans should also be removed to prevent the accumulation of excess paint, and any signs should also be covered. The excessively rusted areas should be treated with anti-corrosion agents before applying the paint. 

Flow coating or spraying?

While most experts suggest spray-painting the transformer surface, the radiators do well with flow coating to ensure uniform and complete protection. It provides 100% coverage to the tubes, stabilizer bars, fins, joints, and seams, as well as other inaccessible areas within the banks. The professionals will build a containment system around the radiator banks to protect the environment and also reuse the paint that flows down the tubes. 

Removing old coatings

If the transformer was painted before, you should regularly inspect the inaccessible areas for flakes, peel offs and blisters. A heated paint stripping chemical that should only be handled by professionals to prevent unfortunate incidents can be used to strip the paint off. Later, the bare surfaces should be treated properly before being repainted. 

Wrapping it up

Constant care and routine inspection can add more years to the electrical transformers and prevent flashovers because of contamination, wildlife contact, or other reasons. Talk to an expert regarding other maintenance requirements besides painting to ensure the seamless performance of the towers.
