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, ...

How Telecom Power Systems Help Extend Battery Life and Reduce Site OPEX

Sep , 24 2026

Quick Answer Battery replacement is one of the major long-term operating costs of telecom base stations. Although batteries may be designed for a 10-year lifespan, real-world conditions often cause capacity degradation within only 5–6 years. Reducing battery aging requires more than selecting better batteries. A complete telecom power solution should include intelligent charging management, ...

Wide Temperature Telecom Power Supply: Reliable Power Solution for Harsh Outdoor Base Station Environments

Sep , 27 2026

Quick Answer Outdoor base stations operate in diverse environments, from extremely cold regions to high-temperature and high-humidity areas. A standard indoor power supply may not withstand these conditions for long periods. A wide temperature telecom power supply is designed with low-temperature startup capability, high-temperature derating control, condensation protection, intelligent cooling, a...

How to Store Lithium and LiFePO4 Batteries Properly

Sep , 28 2026

Lithium batteries are designed for reliable, long-term performance, but proper storage is still important when the battery will remain unused for an extended period. Whether you are storing a battery during the winter, keeping a backup battery for emergencies, or temporarily taking an RV, UPS, or solar system out of service, the right storage practices can help minimize unnecessary battery ...

Wind Power vs Solar Power for Home: Cost & Best Choice

Oct , 09 2026

For most homes, solar power is the better first choice because it is easier to site, predict, install and maintain. Residential wind can be competitive when a property has strong unobstructed wind, enough land for a properly elevated tower and favorable local rules. Where both resources are strong, a wind-solar-battery hybrid can offer better generation coverage. Here is the short comparison. Fact...

Why Does the Main Breaker Trip First? Understanding Selective Protection in DC Distribution Systems

Oct , 09 2026

Quick Answer When a branch short circuit causes the main breaker to trip first, the problem is not necessarily that the breaker is too small or too large. A more common cause is poor selectivity and coordination between upstream and downstream protection devices. A well-designed DC distribution system should isolate a fault as close to its location as possible. Ideally, a short circuit on one bran...
