INVESTIGATION AND EVALUATION OF LOCAL LIQUID DIELECTRIC FOR POWER TRANSFORMER INSULATION
ABSTRACT This work investigates and evaluates local liquid dielectric for insulation of power transformers. Considering the importance of transformer insulation the investigation is borne out of the need to develop the capacity for local production of transformer dielectric. Natural esters of vegetables origin have been found to have the suitable dielectric properties for them to be used as replacement dielectric fluids for mineral oil. However vegetable oil has poor resistance ...
