In order to improve overall HV plant efficiency, there is increased use of thermosyphon technology to provide temperature control, replacing conventional pumps, fans and radiators. Hydrofluoroethers [C4F9OCH3] and Fluorinated ketone [CF3CF2C(O)CF(CF3)2] are two low global warming potential coolants. One use of these fluids in high voltage plant is as the coolants within a thermosyphon. This project aims to characterise the dielectric properties of the candidate coolants and their coupled thermal-electrical performance.
