• Overloading of capacitor banks due to harmonic resonance. 
• Overcurrent during capacitor bank switching.
• Short capacitor lifetime
• Overheating of supply system
• Interference of network and data transmission systems.
• Utility waveform distortion 
• Faults and trips on voltage sensitive systems and devices

The voltage across the terminals of the capacitor will increase the output voltage by 7% because of the inductive reaction of the reactor. The input value is at 415V, add the 7% inductive reaction, and this will give you a total output of 440V. 

In detuned power factor correction systems, the presence of higher voltage rated capacitors and reactors causes a difference between rated capacitor power and obtained reactive power. The obtained power must be calculated in order to avoid low compensation.
