The fire point is the most critical factor to consider when specifying transformer fire safety.

Transformers are critical assets in the electrical grid and their fire safety is paramount to ensuring the stability and reliability of power systems. One of the emerging solutions for transformer fire protection is the use of FR3 natural ester fluid, which is gaining traction in the industry due to its superior fire-protection capabilities and environmental benefits.

The risks associated with transformer fires are significant especially with mineral oil-based transformers, which are prone to igniting in the event of overheating or failure. This concern has driven focus on finding alternatives to traditional transformer oils with FR3 fluid standing out as an optimal solution.

Why FR3 fluid?

Cargill’s FR3 fluid is derived from natural esters, making it biodegradable and less flammable than its mineral oil counterpart. The fluid’s fire point is significantly higher than that of mineral oils, reducing the risk of transformer fires under high-stress conditions.

The use of FR3 fluid in transformers offers several advantages:

• High fire safety: With a fire point over 300°C, the risk of ignition is greatly reduced.
• Environmentally friendly: FR3 fluid is biodegradable and non-toxic, mitigating the environmental impact in case of leaks.
• Improved thermal performance: FR3 allows transformers to operate at higher temperatures, extending the lifespan of the equipment.
