Capacitor banks are designed for an original load. Over time, this changes. This can lead to the original capacitor bank being insufficient or unsuitable for the new situation. It can also be the case that the bank enters in resonance with the installation and becomes a harmonic generator, worsening the efficiency level of the installation.

A capacitor (or condenser) is an electrical device that can store energy in the electric field between a pair of closely-spaced conductors (called ''plates''). When voltage is applied to the capacitor, electric charges of equal magnitude but opposite polarity build up on each plate. They are used in electrical circuits as energy-storage devices.

Capacitor banks generally require very little maintenance because they are static type of equipment, but don't be fooled by this statement. Capacitors are well known for their dangerous reaction when something goes wrong. Standard safety practices should be followed during installation, inspection, and maintenance of capacitors.
Initial Inspection Measurements and Energization Procedures During the initial inspection before energization of the capacitor banks the following measures should be taken: Measure #1 – Verify proper mechanical assembly of the capacitor units, clearances as per the electrical code, and soundness of the structure of all capacitor banks.
