                                                    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

                                                    Solution applicable to small to medium-sized buildings

                                                    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 analyzes the current upline in real time from the non-linear loads and sends out a compensating current via its power line.

                                                    > 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
                                                    > Minimizes system losses and demand power
                                                    > Lowers outage risk
                                                    > Extends equipment lifetime
                                                    > Reduces wire heating (especially neutral)
