The first step to improving energy efficiency is being able to measure and evaluate the amount of power actually being consumed. Any deviations from normal values can be used to identify the condition of the machine and evaluated through the use of monitoring systems such as the EnMon energy monitoring package included in B&R's (Roswell, GA) APROL process control system. The new X20AP energy measurement module from B&R:

  • Measures voltages, currents, frequencies, and reactive components on all phases.
  • Elevates the module to the highest level of precision  when current and voltage measurements are up to the 31st harmonic state.
  • Preprocesses signals and provides measurements together with calculated effective performance values as sets of digital variables.
