The AQ-C255C capacitor bank protection device has been specifically designed for the protection of capacitor banks. It includes voltage protections in addition to the new power factor controller that functions as the control unit of an automatic capacitor bank system and can control up to five (5) capacitor banks.
I used to work for a company that made motor protection systems that were used in petrol pumps. They used a 0,1uF X2 400vac capacitor in series with a 100R 0,25W carbon film resister across all the motor relay contacts. As …
Capacitor bank protection 1. Unbalance relay. This overcurrent relay detects an asymmetry in the capacitor bank caused by blown internal fuses, short-circuits across bushings, or between capacitor units and the racks in which they are mounted.. Each capacitor unit consist of a number of elements protected by internal fuses.
In distribution systems, these capacitors provide reactive power to offset inductive loading from devices like motors, arc furnaces and lighting loads. The incorporation of capacitors into a power distribution system offers economical and operational benefits including increasing system load capacity, reducing losses and improving power factor.
choice of the devices for the switching of the capacitor banks and the filtering of the harmonics. In fact, after a first descriptive part, the ABB offer is illustrated in terms of power factor correction devices, intended not only as suitable capacitors, but also as those devices able to carry out switching and protection of the capacitor banks.

What is a Capacitor? Capacitors are one of the three basic electronic components, along with resistors and inductors, that form the foundation of an electrical circuit a circuit, a capacitor acts as a charge storage device. It stores electric charge when voltage is applied across it and releases the charge back into the circuit when …
