8.2: Capacitance and Capacitors
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.

What is Reactive Power Compensation? – Capacitor Connect
Methods of reactive power compensation. In most cases, the compensation is capacitive. A system may use capacitors in parallel (shunt) to line, or it may be in series, incorporated in the transmission line circuit. Depending on application, the compensation may be done using passive devices, active electronic circuits or …
Star and Delta Connection of Capacitors
Delta connection of capacitors requires two bushings. Since there is no connection to ground, the capacitor bank cannot be a ''sink'' for any ground currents or zero sequence currents. Individual branch of the delta connected capacitor need to be protected against phase-phase short circuit by a current limiting fuse.
