Signs Your Company's Transformer Needs Professional Maintenance

Posted on: 29 January 2025

Transformers are critical components in keeping your business's electrical systems running smoothly. Without proper maintenance, however, they can develop issues that may disrupt operations, lead to costly repairs, or even pose safety risks. Knowing the signs that your company's transformer requires professional attention can protect your investment and prevent downtime. Below are some key indicators to watch for.

 

Overheating or Unusual Temperature Fluctuations

One of the earliest warning signs of a transformer needing maintenance is excessive heat. Transformers are designed to operate within a specific temperature range, and any sudden increase in heat could indicate internal issues such as overloading, a failing cooling system, or insulation problems. Infrared thermography can often detect hot spots before they escalate, helping you address the issue proactively.

 

Strange Noises

Transformers typically emit a low humming sound during operation, which is normal. However, if you begin to notice unusual noises such as buzzing, clicking, or popping, it may signify internal damages or malfunctions. These noises often indicate issues with the transformer’s core, windings, or electrical connections, which require immediate inspection by a professional.

 

Leaks or Visible Damage

Any form of oil or fluid leakage from a transformer should be taken seriously. Leaks can compromise the cooling and lubrication systems, leading to overheating or reduced efficiency. Additionally, visible signs of physical damage like cracks, rust, or corrosion can indicate that the unit has sustained wear and tear over time and needs expert evaluation.

 

Fluctuations in Power Delivery

Constant or frequent voltage fluctuations are another red flag. If your transformer is no longer delivering stable power to your facility, it could be a result of deteriorated windings, poor connections, or other internal failures. Consistent power disruptions not only hinder operations but may also damage other essential equipment.

 

Alarming Smells

Foul or burning smells originating from your transformer could signal serious issues such as insulation failure or overheating components. These smells often result from materials inside the transformer breaking down due to excessive heat or electrical stress. Ignoring these signs may lead to catastrophic failure, so immediate professional intervention is crucial.

 

Irregular Testing Results

Regular transformer testing and monitoring can provide valuable insights. If diagnostic results show anomalies like high dissolved gas levels in the transformer oil or irregular insulation resistance, it’s a clear indication that maintenance is required. These tests are essential in catching early issues that may not be immediately visible or audible.

 

If your company’s transformer is showing any of the signs mentioned above, don’t wait to act. Contact an electrical maintenance provider, such as Power Substation Services.
