The difference in how series and shunt capacitors regulate the voltage and reactive power flows
At a casual look, a capacitor seems to be a pretty boring and unsophisticated device, that is, two metal plates separated by a dielectric insulating material. Couldn’t be simpler than that. The capacitor has no moving parts but instead functions… Read more
