Efficiency Improved Load Sensing System—Reduction of System Inherent Pressure Losses
Energies, 2017 Although more efficient than e.g., constant flow systems, hydraulic load sensing (LS) systems still have various losses, e.g., system inherent pressure losses (SIPL) due to throttling at pressure compensators.

Electrostatic charge measurement in hydraulic circuits [PDF]
Linköping Electronic Conference Proceedings, 2013 Electrostatic charging of hydraulic circuits is recently becoming an issue as low conducting hydraulic fluids are increasingly in use. Charge generation is more likely to accumulate and build up large voltages. These high charge accumulations are hazardous as they can damage system components such as filters, which can eventually lead to system failure.
