Shunt capacitor switching in distribution and transmission systems
The switching devices associated with different loads in distribution and transmission networks have different switching duties to fulfil with sometimes contradicting performance requirements. Thus, a switching device intended to switch reactors might require other abilities than a device to switch capacitors. In this Technical Brochure (TB) the switching …

Fundamentals | Capacitor Guide
Where E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.
