What Are the Benefits of Natural Ester Transformers?

Regular power transformers traditionally use mineral oils to insulate and cool their parts. However, you can also buy natural ester transformers that use ester fluids in place of mineral oils.

What are the advantages of using natural ester transformers?

Thermal Performance

The oils in transformers need to have good heat transfer properties. They ensure that their devices can dissipate heat and cool effectively.

While mineral oils can do this job, natural ester fluids are more effective. They have more thermal stability and transfer heat more efficiently. Their transformers don't suffer from as many heat overloads and get the cooling they need under even stressful operating conditions.

Ester fluids are also dielectrically stronger than mineral oils. They can manage higher electrical stresses without losing their insulating properties.

Oxidisation Resistance

Oils can oxidise in transformers. Over time, regular use and age will degrade the quality of the oil. This reduces its effectiveness and can damage its transformer.

Ester fluids have better oxidisation resistance than mineral oils. They are less to damage their devices, so you will have lower transformer repair or maintenance costs. Your transformer should also last longer before you need to replace it.

Fire Safety

Any oil could catch fire if it heats up to a certain temperature. Ester fluids have higher fire-point temperatures than mineral oils. They are less likely to accidentally catch fire or to cause an explosion if their transformers develop a problem, such as an electrical failure or internal fault.

These fluids enhance your fire safety. They will keep your workers, equipment, and facility safer.

Noise Reduction

Transformers can be noisy. They can contribute to noise levels and pollution in their working environments. However, you might struggle to reduce their operating noise levels.

The improved thermal capabilities of natural ester devices also reduce their operating noise. These fluids prevent hot spots from developing on transformers. These hot spots can create excess noise.

Environmental Benefits

Ester fluids are derived from vegetable oils. Unlike other oils, these fluids are renewable and biodegradable.

They also have a lower carbon footprint than mineral oils. Leaks and spills are less likely to cause the same levels of environmental contamination as accidents with mineral fluids.

So, a natural ester transformer helps make your facility more environmentally responsible. If you have to meet local, state, or national environmental standards, then using these transformers will help you comply with sustainability goals and standards.
