          Reduce power loss by filtering harmonics


          Main drivers

          I need to reduce the overall harmonics generated by my factory’s variable speed drives and uninterruptible power supply. My budget is limited, and the solution has to be simple.

          Solution in brief

          Install AccuSine PCS active filtering for your electrical installation

          Variable speed drives and uninterruptible power supplies constitute non-linear loads. They use a fundamental sine wave (the same frequency as the network) and generate additional harmonics waves whose frequencies are multiples of the network’s frequency.

          The AccuSine PCS active filter constantly generates an equal yet opposite current to the harmonic currents generated by non-linear loads, leaving only the fundamental frequency on the network.

          The AccuSine PCS is fed from a specific outgoing feeder. It detects and analyses the current upline in real time from the non-linear loads and sends out a compensating current via its power line.


          Benefits for end users

          • Harmonic filtering reduces power loss in the upline circuit and equipment by 10%
          • Ensures harmonics of less than 5%
          • Reduces overloading and frees up additional useable capacity
          • Minimises system losses and demand power
          • Lowers outage risk
          • Extends equipment lifetime
          • Reduces wire heating (especially neutral)

          Benefits for professionals

          • Easy to install
          • Compensation automatically adjusted depending on load
          • Easy upgrades and add-ons
          • Optional power factor correction possible (recommended by utilities)
