Evaluation of Volumetric Concentration of Ferrofluid Useful For Heat Extraction in High Power Transformers
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 6
Abstract
In conventional method, transformer oil is used as a coolant under natural convection. Transformer oils have low cooling efficiency due to low thermal conductivity. This work proposes the use of ferrofluid with transformer oil as a hydrocarbon carrier and evaluation of volumetric concentration thereof. Ferrofluid is a super-paramagnetic fluid and is used as a coolant. This enhances heat extraction from high power transformers. Addition of magnetic nanoparticles in transformer oil treated with a suitable stabilizer enhances the thermal conductivity of mixed solution and cooling efficiency thereafter. It also increases the dielectric strength of transformer oil. This thermal property of ferrofluid changes with volumetric concentration as well as diameter of magnetic nano particles. Therefore evaluation of volumetric concentration is important to make sure proper ferrofluid is used in electrical devices such as high power transformers.
