Transformer Ester Fluids by Midel.
Transformers are often cited as one of the top five high-risk assets. Accordingly, Midel fluids are helping to safeguard these critical assets for transformer OEMs, Utilities and industrial asset owners.
Midel’s natural ester and synthetic ester fluids enable transformers to work harder (at 20% overload), for much longer. They provide unrivaled risk mitigation through their high fire points and, compared to mineral oil, superior moisture tolerance. In addition, these ester fluids are readily biodegradable and non-toxic, presenting no threat to the environment.
Why use an ester fluid in transformers?
Cost Savings
Advantages of Midel ester fluids, such as their high fire and flash points, biodegradability, oxidation stability and excellent moisture tolerance, are acknowledged throughout the power industry and lead directly to cost savings.
Fire Safety
Midel fluids have an impeccable fire safety record – they are classed as less flammable fluids for dielectric purposes, meaning they require lower fire safety measures than mineral oil. Midel’s fire safe properties allow for their use indoors and in other critical areas where mineral oil would not be acceptable.
Environment Protection
MIDEL ester transformer fluids are fully and readily biodegradable, unlike mineral oil. They present a much lower risk to the local environment if spillage occurs. Using Midel ester fluids may also reduce the need for containment around the transformer, thus reducing the amount of real estate needed.
Business Continuity
Midel fluids helps mitigate risks for critical power infrastructure, making a valuable contribution to a robust business continuity strategy. They are a critical part of a move towards the adoption of more effective materials used to safeguard transformers and power supplies.
Retrofilling with ester fluids
Retrofilling is the process of replacing the existing insulating fluid (e.g. mineral oil) in an operational transformer with new fluid. Doing so effectively upgrades the transformer.
When retrofilling also involves the use of an advanced fluid such as synthetic ester fluid or natural ester fluid, it then delivers further demonstrable benefits.
Dissolved Gas Analysis and Ester Fluids
Like all transformer oils, Midel ester fluids can be tested during operation in order to spot any possible faults before they become serious.
One of the ways this is done is through Dissolved Gas Analysis (DGA), where the identification of key gases and rate of gas production can be used to determine the nature and severity of any problems with your transformer.
