  • Additives to prevent electrostatic charge buildup in fluids in high voltage systems
    Patent number: 4694375
    Abstract: An ionic material is added to a halocarbon insulating fluid used to cool high voltage equipment in order to prevent the buildup of electrtostatically generated charge. The ionic additive allows leakage of charge from the insulating fluid so as to prevent dangerously high voltage buildup while at the same time withstanding the high voltage applied to the system.
