Why is CT Selection the Core of AHF System Performance? The current transformer (CT), as the "sensing organ" of the active harmonic filter (AHF), directly affects the accuracy of harmonic detection and the dynamic response speed. If the CT is not properly selected, the following problems may occur: Failure of Harmonic Compensation: Low-frequency or high-frequency harmonics are missed in det...
Power Factor Correction: Boost Efficiency & Save Energy What is Power Factor Correction? Power factor correction (PFC) fixes a hidden problem in electrical systems: wasted energy. Imagine your equipment pulls 100 units of power from the grid, but only 70 units do real work (like running motors). The other 30 units are "reactive power" — useless energy that heats wires and inflates...
