ABB has introduced BIOTEMP®, a high oleic, high fire point natural ester dielectric insulating fluid, which has a much reduced risk of fire initiation and propagation compared with the conventionally used mineral oil. What is it about a BIOTEMP-filled transformer that makes it one of the safest liquid-filled transformers on the market? Ester-Based Oils as Replacements for Transformer Mineral Oil PSU-ECE-PGE-009. 2 Ester-based Dielectric Oils. Ester oils are dielectric coolants designed for use in distribution and power class trans- formers. They may be natural or synthetic in origin, deriving from commodity seed oils or inorganic feedstocks. • Natural ester (dielectric fluid) insulating liquid is made from the oil of naturally grown vegetables • Several different varieties have been made but the most widely used is FR3 which is made from soybean oil • Initially designed to be an environmentally friendly alternative to less flammable dielectric fluids like PCBs and High Molecular Weight ... When using FR3 oil, a natural ester derived from renewal vegetable oils, you are providing: Improved Fire Safety: FR3 Oil is 2 times greater than the flash and fire point of mineral oil; Transformer Life and Loadibility: FR3 oil helps to draw out retained moisture and absorb water driven off by aging paper. “This workshop is a result of our ongoing technology scanning initiatives, which have revealed that OEMs and utilities around the world are moving towards the adoption of environmentally friendly esters as the chosen insulating oil for transformers”, explained Eskom’s GM for Power Delivery Engineering, Mr Prince Moyo. India Introduces New Synthetic Esters Standard for Transformers. Indian authorities have opened up the door for synthetic esters to be used as dielectric fluids in transformers by adopting the new standard IS 16081, an equivalent to IEC standard 61099, effective from June 2013.

Nov 01, 2019 · I'm looking at a transformer assembly job, the transformer is from Siemens and is insulated with Ester oil. I've only worked with Mineral oil before, are there any differences in the way we should handle the Ester oil? My initial thoughts would be new pump and hoses so as not to contaminate with the mineral oil residue in our existing equipment. Dec 22, 2012 · The test results concluded that the natural ester fluid was the least oxidation unstable and the synthetic ester is the most oxygen stable transformer fluid, even outperforming mineral oil. Oxidation test methods specifically for natural esters will be included in the upcoming IEC standard. When using FR3 oil, a natural ester derived from renewal vegetable oils, you are providing: Improved Fire Safety: FR3 Oil is 2 times greater than the flash and fire point of mineral oil; Transformer Life and Loadibility: FR3 oil helps to draw out retained moisture and absorb water driven off by aging paper.

mineral oil and ester fluids. Design calculations and design rules for the dielectric and thermal performance of mineral oil – filled power transformers have been developed and continuously enhanced through extensive operating and testing experiences over the years. It is, therefore, critical When using FR3 oil, a natural ester derived from renewal vegetable oils, you are providing: Improved Fire Safety: FR3 Oil is 2 times greater than the flash and fire point of mineral oil; Transformer Life and Loadibility: FR3 oil helps to draw out retained moisture and absorb water driven off by aging paper. The synthetic ester MIDEL 7131 and the natural esters MIDEL eN 1204 (rapeseed/canola) and MIDEL eN 1215 (soya) all provide the crucial combination of fire safety and environmental protection properties absent in mineral oil. The MIDEL range of ester transformer fluids delivers an array of distinct benefits when used in a power transformer or distribution unit. Because we offer three different ester fluids, our customers can choose the one that best suits their specific installation and performance criteria. Mainly following types of oils are used in Transformer: A. Mineral Oil: These are Petroleum products and are mainly following two types: 1. NAPTHANIC OIL : Naphtha oil is more easily oxidized than Paraffin oil but oxidation product i.e. sludge in ...
Aug 12, 2019 · Read more on transformers. According to Baraldi, Cargill will increase its investment in South Africa to meet Eskom’s and the DTI’s goals of replacing transformer fluid, typically mineral oil, with fire-safe and biodegradable natural ester fluid for the electrical grid. This material under most intended uses would become used oil due to contamination by physical or chemical impurities. RECYCLE ALL USED OIL. While being recycled, used oil is regulated by 40 CFR 279. Use resulting in chemical or physical change or contamination may also subject it to regulation as hazardous waste. Focused on transformer fluid supply, preparation, handling, testing and disposal. Achieved by staff, systems, dedicated assets and a focus on Customer Service. Enviroil is a leading Southern Africa supplier and handler of mineral insulating oil (transformer oil) and ester fluids.
Ester 2 (purple) starts with an acid number of 1, while Ester 3 (red) begins with an acid number of 3. Esters 2 and 3 are highly degraded by the end of the test. Catalyst Residue. Esters are usually made with a catalyst to accelerate the synthesis, but ester catalysts also accelerate the degradation of ester in the presence of water.
