Learn MoreThese banks are put in substations for this use. To optimize the voltage profile, several capacitors are also linked in series. As observed in the power factor angle above, when this bank is installed, the capacitor current—also known as the charging current—always leads the voltage.
Learn MoreWhy Do We Use Capacitor Banks in Substations: Substations are critical components of the electrical grid, responsible for transforming voltage levels and distributing power to various load centers. The use of capacitor banks in substations serves several purposes:
Learn MoreExternally Fused – For this type of connection, each fuse unit is connected externally to the capacitor bank. This helps to save the capacitor bank from faults like surge voltage, temperature, etc. without any interruption in the operation. Internally Fused – In this type, the fuse is kept inside the casing of the capacitor bank.
