SPD Maintenance: Why Surge Protective Devices Cannot Be Installed and Forgotten

Aug , 31 2026

Quick Answer A Surge Protective Device (SPD) cannot be considered permanently effective simply because its indicator window remains green. The indicator only shows part of the device status. Actual protection performance also depends on installation quality, grounding conditions, upstream protection coordination, wiring length, and previous surge events. During lightning strikes, grid switching, o...

Why a Running Fan Does Not Mean Your Power Supply Cooling Is Working Properly

Sep , 02 2026

Quick Answer A running fan only shows that the fan is operating. It does not mean the power supply is effectively cooled. Actual cooling performance depends on airflow, air pressure, ventilation design, ambient temperature, and installation conditions. Long-term high temperature can accelerate component aging, reduce available power capacity, and shorten power supply lifespan. Key Takeaways...

Harmonics in Power Systems: Why Normal Operation Does Not Mean the System Is Healthy

Sep , 08 2026

Quick Answer The biggest challenge with harmonics is that they usually do not cause immediate equipment failure. A power system may continue operating normally, while distorted current gradually increases losses, temperature rise, and stress on the entire power distribution system. For systems with rectifiers, UPS systems, battery chargers, variable frequency drives, and switching power supplies, ...
