Some electrical equipment (including standard AC drives) are capable of distorting the mains AC supply waveform.  In extreme circumstances this can lead to troublesome heating of electrical equipment and even premature failure.  Harmonic distortion must be contained within legal limits.  CT Harmonic Calculator will help you to evaluate the potential problem and economically meet the required standards for your installations.

• Provides harmonic analysis of drive systems including comparison with the limits required by the IEEE519-1992 standard for power quality.
