Mechanically switched capacitors (MSC) or filter circuits (FC) allow automatic switching of the capacitor banks according to the requirement of the network system and can also be switched on and off manually. MSC increase voltage at the point of connection. Decreasing voltage through mechanically switched reactor (MSR)
Mechanically switched capacitors (MSC), mechanically switched reactors (MSR) or filter circuits (FC) are both proven solutions for fairly constant or predictable voltage or reactive power profiles. Transient and harmonic damping
A more advanced variant is a mechanically switched capacitor with damping network (MSCDN). This filter circuit provides reactive power to the grid by using a capacitive filter structure. This limits the amplification of existing harmonics in the grid, and further enhances grid stability.
The final conclusion of the work presents the importance of the Mechanically Switched Capacitors (MSCs) to a transmission system and a complete introduction of the main aspects for the equipments dimensioning and energization, contributing for the quality of the power transmission system.

A switched capacitor (SC) is an electronic circuit that implements a function by moving charges into and out of capacitors when electronic switches are opened and closed. Usually, non-overlapping clock signals are used to control the switches, so that not all switches are closed simultaneously. Filters implemented with these elements are termed switched-capacitor filters, which depend only on the ratios between capacitances and the switching frequency, and not on precise resistors. T…
