Power quality is a growing issue in Africa. Many sites now use solar inverters, VFDs, battery systems, UPS units, and LED lighting. These loads improve efficiency, but they also create harmonic currents and reactive power problems. This is one reason harmonics damage transformers in modern facilities. In many African industrial power systems, transformers carry the stress of the whole network. Whe...
Why EV Charging Stations Need an Active Harmonic Filter EV charging stations are expanding quickly in commercial buildings, parking structures, fleets, and public infrastructure. As more fast chargers connect to the electrical system, power quality becomes a serious issue. Many charging stations use high-power electronic converters. These are nonlinear loads. While they improve charging efficiency...
