Extend mechanical and electrical operations as enabler for grid flexibility

The integration of renewable energy sources and the ongoing energy transition have raised the demand for flexibility in managing and controlling electrical grids. New protection equipment is asked to address increased electrical stress, transient mitigation and frequent operations, which all pose design challenges to reduce electrical and mechanical wear, extend lifespan, and minimize maintenance cycles. Highly efficient mechanical actuators and electrical contacts with good lubrication are crucial elements in keeping the kinematic chain’s operational performance in mechanical equipment, yet the traditional solutions based on oil and grease lubrication have limitations on these sliding metal-to-metal contacts.
