Capacitor fuse blow: At resonant conditions, due to high capacitor currents fuses will be operated. Capacitor failure: Insulating layers of the capacitors can be damage due to overtime overheating or excessive voltage stresses. Voltage distortion: For resonant condition the distortion causes due to one or two closely spaced harmonic orders.
