Abstract

Condition assessment of insulating oils based on critical properties is of prime importance to evaluate the suitability towards high voltage transformer application. In the recent development, high giant dielectric CaCu3Ti4O12 (CCTO) nanopowder attracted researchers for use in development of nanofluid due to its high permittivity with reduced loss even at higher temperatures. Till-date, the condition assessment of high dielectric nanofluids are in nascent stage and an attempt has been taken in this study to compare the performance of mineral oil and natural ester oil based CCTO nanofluids at 0.01 vol.%. Results proves that, natural ester oil based CCTO nanofluids show enhanced dielectric and decreased PDIV values than mineral oil based CCTO nanofluid. Therefore, it is suggested that natural ester oils based high dielectric CCTO nanofluids of 0.01 vol. % may be used as an alternative and suitable insulation for the power industries.

矿物油和天然酯油基高压高介电CCTO纳米流体的性能研究

根据绝缘油的临界性能对绝缘油进行状态评估，是评估绝缘油在高压变压器中的适用性的关键。近年来，高巨介电ccu3ti4o12 (CCTO)纳米粉体因其高介电常数且在较高温度下仍能降低损耗而被广泛应用于纳米流体的研制。到目前为止，高介电率纳米流体的条件评估还处于起步阶段，本研究试图比较0.01%体积下矿物油和天然酯油基CCTO纳米流体的性能。结果表明，天然酯油基CCTO纳米流体比矿物油基CCTO纳米流体具有更高的介电值和更低的PDIV值。因此，建议以0.01 vol. %的天然酯油为基础的高介电CCTO纳米流体可作为电力工业的替代和合适的绝缘材料。
