Maintenance Tips for Every AC Charging Cable and EV Port Maintaining an AC charging cable and your EV port is very important. Good care helps your car charge fast. It also keeps you and your vehicle safe. This guide offers simple tips to help you keep your equipment in top shape. Part to Clean What to Use Why It Matters Cable Jacket Damp cloth with mild soap Removes road salt and gri...
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...
Medium Voltage STATCOM for Mining Mining sites depend on stable medium voltage power. Crushers, conveyors, pumps, mills, hoists, compressors, and ventilation systems all place heavy demand on the electrical network. These loads do not always operate at a steady level. They start, stop, ramp up, and change throughout the day. This can create voltage fluctuation, poor power factor, and reactive powe...
Introduction: The High Cost of the "Invisible Killer" in July 2026 As we move further into the industrial energy transition of 2026, the reliance on diesel generators, gas turbines, and isolated microgrids remains a mission-critical reality for remote mining operations, large-scale agriculture, and telecommunication base stations. Yet, an "invisible killer" continues to bleed operational bu...
Three-Level AHF Stops Capacitor Failures in VFD Plants Capacitor banks can fail under VFD harmonic loads. Learn how a three-level active harmonic filter reduces THDi and supports capacitor-bank protection. A recurring VFD-plant problem looks like this: capacitor banks fail repeatedly even after replacement. The capacitors may not be the root cause. Nonlinear loads can inject 5...
Why Professional Power Quality Design Before Buying AHF, SVG, or STATCOM A 480V switchboard can look normal during a routine inspection and still trip the generator every time the UPS load transfers. The breaker records show high neutral current, the capacitor bank contactors run hot, and the plant team sees THDi above the local utility limit. This is where Power Quality Design matters more...
Stop Hidden Power Costs from Automotive Dynamic Loads: Benefits of Power Quality System Upgrade Automotive assembly lines operate with extreme load volatility. High-power lifting equipment and robotic welders demand instantaneous reactive power during startup cycles. Traditional capacitor-based compensation systems fail to track these millisecond-level transients, leading to severe power fa...
A plastics extrusion plant in Ohio replaced motor starters with VFDs and cut drive energy use by 4%. Three months later, its 1000 kVA transformer ran 18 K above nameplate temperature, two capacitor banks tripped on overcurrent, and the utility applied a power-factor penalty. THDi on the 480 V bus measured 32% at full production. Adding capacitors would make that worse, not better. The fix i...
