Capacitor Banks in High Voltage Grids and Train Systems
Capacitor banks are integral components within high voltage grids and train systems, serving various critical functions such as power factor correction, voltage regulation, and improving the quality of electrical power. By storing and releasing electrical energy, capacitor banks help manage load demand, stabilize voltage levels, and reduce losses in power systems.
Functionality and Benefits
Capacitor banks consist of multiple individual capacitors connected in parallel or series, designed to provide the electrical system with reactive power support. This not only optimizes energy consumption but also ensures the efficient operation of the power grid and train system electrification, leading to significant cost savings and enhanced system reliability.
