Various methods have been tried to alleviate the potential of static charge accumulation in fluid systems. Among them are anti-static additives, which may not be suitable for turbine oils; the use of conductive mesh downstream of the filter material, which has limited effectiveness in preventing charge accumulation in the fluid; and increasing the time for the charge to decay, which requires a change in the system design. Filtering the fluid at a lower flow density (i.e., increasing the filter size) does rectify the problem, but it is not a viable option for every system. Several manufacturers have introduced filters with filtration media designed not to generate a charge to the same extent as the standard glass-fiber-based materials.
