Certifications and Approvals for Cargill Envirotemp fluids
Cargill ester dielectric fluids have undergone extensive testing to meet the rigorous standards and performance criteria set by the industry. Below is a brief description of the standards in which our dielectric fluids are approved.
Factory Mutual Global:
Factory Mutual Global provides insurance and property loss prevention engineering for commercial and industrial clients worldwide. FM Approvals certifies industrial and commercial products and services for companies worldwide. When a product or service meets the standards of FM Approvals, it is issued the “FM APPROVED” mark to signify it will perform as expected and support property loss prevention. FM Approvals backs its evaluations with scientific research and testing.
In the Factory Mutual Approval Guide. Electrical Equipment Division, under the category of Transformer Fluids, there is a sub-category of Less Flammable Transformer Fluids. In this sub-category, Envirotemp™ FR3 Fluid is listed “FM Approved”. There is a note that the fluid is FM Approved as component for use in FM Approved liquid-insulated transformers. FM Approved FR3 fluid is an option to help meet the National Electrical Code (NEC®) requirements of indoor and outdoor transformer installations in Article 450.
In addition to approving less-flammable fluids, FM Global also has a transformer approval listing, Approval Standard 3990. The transformer standard describes the requirements for Approval off a transformer assembly, including the requirement to use an FM Approved transformer fluid, such as Envirotemp FR3 fluid. FM approved transformers are available from several transformer manufacturers.
UL (Underwriters Laboratories) globally certifies, validates, tests, inspects, audits, and advises clients on preventing or reducing loss of life and property and to promote safe living and working environments. Included in its service includes listing transformer fluids and dielectric mediums. Envirotemp FR3 is listed in the directory of UL Listed and Classified Products, under both listings: Transformer Fluids (EOVK.MH10678) and Dielectric Mediums (EOUV.MH10678).
In addition to listing less-flammable fluids, UL also provides listing, labeling, and certifying of liquid filled transformers. Transformers can be specified as UL® Listed & Labeled, and/or UL® Classified. The UL listing is a verification of the design and construction of the transformer to the ANSI® and IEEE® standards. UL listed transformers are used for complying with relevant state and local electrical codes. Using transformers with the UL Combination Classification/Listing is another way in which to comply with certain NEC Article 450 requirements. This combines the UL® listed transformer with a UL® Classified Less-Flammable Liquid. UL listed transformers using FR3 fluid.
The Federal Energy Regulatory Commission (FERC) is an independent federal agency that regulates the interstate transmission of natural gas, oil, and electricity. Its mission is to provide reliable, efficient and sustainable energy services at a reasonable cost for energy consumers. In 2011, FERC approved an accounting petition filed by a public utility to capitalize all costs incurred to retrofill a transformer with bio-based dielectric coolant, such as Envirotemp FR3 fluid, under the FERC Uniform System of Accounts. This allows utilities to upgrade their existing substation transformers with a more favorable financial method.
