Mechanically switched capacitor
Under heavy load conditions, MSCs provide voltage control and grid stabilization in a simple and cost-efficient way. MSRs provide stability under low load conditions or can be used at the end of long, radial AC lines. However, usage is somewhat limited as the capacitors need to discharge for several minutes after switching off an MSC bank.

Open substation air capacitor bank | Technical
Eaton''s Cooper Power series open air capacitor banks are available with vertically or horizontally-oriented capacitor units. Vertical orientation results in bushings at right angles with respect to mounting floor. This type of construction is typically used to limit the bank footprint within the substation area and provide additional safety ...
Capacitor bank and improvement of power factor | PPT
A capacitor bank is a group of several capacitors of the same rating that are connected in series or parallel with each other to store electrical energy . The resulting bank is then used to counteract or correct a power factor lag or phase shift in an alternating current (AC) power supply.
