What is Efficiency ??
What is Efficiency ???




                               Do more with LESS !!




 Comparison of what is actually produced or performed with what can be
 achieved with the same consumption of resources (money, time, labor,
 etc.).
Efficiency in your power
network
 • Financial           • Downtime reduction        • Energy Efficiency


Reduce :
                        Increase availability
 Installation costs
                        Reduce costs associated
   - save space
                        with fault-finding and
   - save time
                        trouble-shooting
 Base product costs
 Running costs
 Upgrading costs




                                   SAVE COST

Power Quality and Harmonics
          Harmonic disturbances are caused by non-
          linear loads.

          Most electronic loads draw harmonic currents
          and hence induce harmonic voltages in
          electrical networks, e.g. :

             ● Power electronic equipment (rectifier, inverter,
               speed controller, dimmer)
             ● fluorescent lighting
             ● welding machines
             ● data processing equipment (computers &
               peripherals)
                                                                       Power Quality


Effects of harmonics in
electrical systems
                    Effects on installations
                       ● accelerated aging of certain equipment
                         (by heating, vibrations)
                       ● electromagnetic disturbances
                       ● motor overconsumption
                       ● damage capacitor banks
                       ● overloads in the neutral conductor
