The amount of coupling capacitance is limited by the common-mode rejection requirement to no more than a few nanofarads. The concept of high frequency power transfer has been in practice with magnetic solutions for decades; it allows reduction of the size and cost of the transformer.
i0generated vary in the same way. It should also be noted that the reactive power generated by the capacitor formed between the ac- tive conductor and the ground plane decreases as the height between them in- creases. Similarly, that generated by the capacitors formed between active con- ductors decreases when the distance between them increases.
By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load. Reduced current also significantly lowers the I 2 R line losses. Capacitors provide a voltage boost, which cancels part of the drop caused by system loads.
Most noticeably, capacitors reduce losses, free up capacity, and reduce voltage drop. Let’s go a little bit into details. By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load.
Switched capacitors can regulate voltage on a circuit. If applied properly and controlled, capacitors can significantly improve the performance of distribution circuits. But if not properly applied or controlled, the reactive power from capacitor banks can create losses and high voltages. The greatest danger of overvoltages occurs under light load.
idiffer from one geometry of the line conductors to another. Likewise, the equivalent capacities and the reactive powers generated differ from one phase to another. With regard to the results in Table 4, we note that the windings of the transformers consume different reactive powers. Table 1. Capacitance values of capacitors formed.

Can transformers be used to adjust capacitors?
Transformers let us trade voltage for current, but the energy entering the low voltage side is still the same energy coming out the high voltage side. So the same volume of capacitance (and thus the same approximate materials and cost) will be needed to do the same job, regardless of which side of the transformer the capacitor is installed on.

I recently learnt about how resonance in an LC (inductor capacitor) circuit could increase the efficiency of the circuit, for application in something like Resonant Inductive Power Transfer. Excuse my naivety, but I couldn''t help but wonder then why don''t transformers also have a capacitor in them to achieve resonance and increase efficiency?
