  • Page 37: Maximum Demand Calculation

    7 Maximum Demand Calculation The maximum power consumption of an installation is an important measurement as most power utilities base their charges on it. Many utilities use a thermal maximum demand indicator (MDI) to measure this peak power consumption. An MDI averages the power consumed over a number of minutes, such that short surges do not give an artificially high reading.

  • Page 38: Thd Calculation

    8 THD Calculation The calculation used for the Total Harmonic Distortion is: THD = ((RMS of total waveform – RMS of fundamental) / RMS of total waveform) x 100 This is often referred to as THD – R The figure is limited to the range 0 to 100%. For low signal levels the noise contributions from the signal may represent a significant portion of the “RMS of total waveform”...
