What are series and parallel capacitor combinations?

These two basic combinations, series and parallel, can also be used as part of more complex connections. Figure 8.3.1 8.3. 1 illustrates a series combination of three capacitors, arranged in a row within the circuit. As for any capacitor, the capacitance of the combination is related to both charge and voltage:

What is the effect of series capacitor in a transmission line?

Figure 1 A transmission line with series-capacitor-compensation applied. Due to the effect of series capacitor the receiving end voltage will be instead of VR as seen from the phasor diagram (Figure 2).

What is the effect of series capacitor in a circuit?

Due to the effect of series capacitor the receiving end voltage will be instead of VR as seen from the phasor diagram (Figure 2).

Why is series compensation important in a parallel circuit?

When the new line with large power transfer capability is paralleled with an already existing line, then it is difficult to load the new line without overloading the old line. In such case the series compensation reduces the series reactance and proper load division among parallel circuit can be done easily.

What are the advantages of a series capacitor?

Load division increases the power transfer capability of the system and reduced losses. Control of Voltage – In series capacitor, there is an automatic change in Var (reactive power) with the change in load current. Thus the drops in voltage levels due to sudden load variations are corrected instantly.
