RC Waveforms

Useful wave shapes can be obtained by using RC circuits with the required time constant. If we apply a continuous square wave voltage waveform to the RC circuit whose pulse width matches that exactly of the 5RC time constant ( 5T ) of the circuit, then the voltage waveform across the capacitor would produce RC waveforms looking something like this:

6 FAQs about [High voltage impact capacitor waveform]

What is the 11th harmonic waveform of a capacitor bank?

Figure 4.29 shows a current waveform of a capacitor bank in resonance with the system at the 11th harmonic. The harmonic current shows up distinctly, resulting in a waveform that is essentially the 11th harmonic riding on top of the fundamental frequency.

Does a capacitor bank experience high voltage distortion during resonance?

A capacitor bank experiences high voltage distortion during resonance. The current flowing in the capacitor bank is also significantly large and rich in a monotonic harmonic. Figure 4.29 shows a current waveform of a capacitor bank in resonance with the system at the 11th harmonic.

What is a harmonic current waveform?

The harmonic current shows up distinctly, resulting in a waveform that is essentially the 11th harmonic riding on top of the fundamental frequency. This current waveform typically indicates that the system is in resonance and a capacitor bank is involved.

How does the voltage drop across a capacitor work?

The voltage drop across the capacitor alternates between charging up to Vc and discharging down to zero according to the input voltage. Here in this example, the frequency (and therefore the resulting time period, ƒ = 1/T) of the input square wave voltage waveform exactly matches twice that of the 5RC time constant.

What causes a good impulse voltage waveform?

Due to the presence of stray capacitances etc, the order of the differential equation governing the impulse waveform is increased, and the practical circuit will have exponential terms to the order of the number of storage elements. To obtain a good impulse voltage waveform, it is necessary to damp out the oscillations caused.

What happens if a capacitor bank has a harmonic current?

These harmonic currents can also cause interference with telecommunication lines and errors in power metering. A capacitor bank experiences high voltage distortion during resonance. The current flowing in the capacitor bank is also significantly large and rich in a monotonic harmonic.
