Regenerative brake - Wikipedia

Regenerative braking is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a form which can be either used immediately or stored until needed. In this mechanism, the electric motor uses the vehicle''s momentum to recover energy that would be otherwise lost to the brake discs as heat.

Comparison of GIS and AIS systems for urban supply networks

bination of HV gas-insulated switchgear (GIS) and HV cable has important advantages over systems with air-insulated switchgear (AIS) and overhead lines. Due to their compactness and flexibility, GIS substations can be lo-ed close to load centers, allowing a much more efficient configuration for both the HV system and the MV distribution network.
