6 FAQs about [Effect of series capacitors on voltage]
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). Thus with series capacitor in the circuit the voltage drop in the line is reduced and receiving end voltage on full load is improved. Series capacitors improve voltage profile.
What is the effect of series capacitor in a transmission line?

Due to the effect of series capacitor the receiving end voltage will be instead of VR as seen from the phasor diagram (Figure 2). Thus with series capacitor in the circuit the voltage drop in the line is reduced and receiving end voltage on full load is improved.
What is a series capacitor used for?
Control of voltage. Series capacitors are used in transmission systems to modify the load division between parallel lines. If a new transmission line with large power transfer capacity is to be connected in parallel with an already existing line, it may be difficult to load the new line without overloading the old line.

What happens if a capacitor is connected to a resistor?
With series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS ( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series. With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply.
How much voltage does a series capacitor increase with load?
On connecting the series capacitor, the voltage reaches 99.85%, 99.66% and 99.49% for the three load cases, respectively. This represents a respective increase in the voltage by 2.23%, 4.42% and 7.2% in conformity to the adaptive nature of series compensation being increased with the load increase.
