绝缘材料是电气设备中导体之间的分隔物，可以防止闪络导致短路或电气故障。隔离在电气设备中至关重要，特别是高压电力设备（HVPE），以确保断路器、电容器和变压器的安全。除了作为隔离器外，绝缘液体材料还起到冷却电器所产生的热量的作用。使用矿物油基变压器的隔离器有各种环境问题，包括非生物降解性、不可再生性和稀有性。由于它环保并被广泛使用，初榨椰子油（VCO）是一种替代的变压器油绝缘材料。本研究旨在利用IEC 156标准和油温调节来确定初榨椰子油（VCO）的击穿电压特性。根据测试结果，加热前（室温）油的击穿电压为14kV，远低于IEC 156标准，而加热到90°后的击穿电压为35kV，110°时为40kV，甚至高于IEC 156的要求。
