Swiss capacitor bank

What is a capacitor bank?

A Capacitor bank is a grouping of several capacitors of the same rating. Capacitor banks may be connected in series or parallel, depending upon the desired rating. As with an individual capacitor, banks of capacitors are used to store electrical energy and condition the flow of that energy.

What is a cab automatic capacitor bank?

Equipped with a power factor controller to regulate their automated operation and monitoring features, CAB automatic capacitor banks remove power factor charges of the electricity bill and reduce the losses of electrical equipment and wiring. CAB: Low voltage automatic capacitor banks to compensate reactive power in circuits with non-linear loads.

What is a capacitor bank & harmonic filter?

Capacitors banks and harmonic filters. Medium and high voltage Capacitors banks and harmonic filters. Medium and high voltage Arteche’s capacitor banks and harmonic filters allow keeping system stability and diminishing the loses, contributing to improving the operative efficiency of electrical grids and power systems.

What is a shunt capacitor bank?

Shunt capacitor banks, also called filter banks, are widely used in transmission and distribution networks to produce reactive power support. ABB's capacitor bank protection is used to protect against faults that are due to imposed external or internal conditions in the shunt capacitor banks.

What causes a capacitor bank to fail?

Internal faults are caused by failures of capacitor elements composing the capacitor units, and units composing the capacitor bank. Other faults inside the bank can be a flashover within the rack (short circuit over a single or multiple series groups of units of the same phase) and rack phase-to-phase and phase-to-earth faults.

What is the purpose of a shunt capacitor protection scheme?

The purpose of the protection scheme is to limit the effect of overload to a safe and acceptable level, and to prevent the abnormal system conditions from damaging the shunt capacitor bank by disconnecting it in case of a loss-of supply condition.
