Surge protection for BMS: when protection may not be needed
More surge protection is not automatically better. A building management system may not need a separate surge protective device at every point if…
Voltage protection rating explained: why lower clamping can help
A lower clamping voltage can mean stronger surge protection, but only when you compare devices designed for the same system. A voltage protection…
Protecting Capital Equipment from Power Surges in Commercial Buildings
A surge can be brief, but the damage can last. Surge protection devices help limit transient voltage before it reaches sensitive equipment. Layered…
Surge Protection for Critical Infrastructure in Commercial and Industrial AC Facilities
For commercial and industrial facilities, surge protection for critical infrastructure means protecting key points in the power system, from the…
SPD Wiring Length Rules and Their Effect on Installed Protection
An SPD’s label isn’t the whole protection story: connection wires can add voltage during a surge. For BS 7671-based installations, the total…
How to Size Surge Capacity for an Industrial Facility
A generator’s required apparent-power capacity is the facility’s real load divided by its power factor: for example, a 400 kW load at a 0.80 power…
Power Surge Damage in Industrial Equipment and Repair Costs
A surge can damage industrial equipment without leaving a visible mark. Identifying power surge damage in industrial equipment means looking for…
Surge Protection for PLC I/O Cards: A Practical Guide
What if the surge disrupting a PLC never enters through the panel’s main power feed? The control cabinet may have incoming power protection, yet…
Surge Protection for Industrial UPS: A Practical Guide
What if the UPS protecting your critical equipment isn’t the whole answer to a damaging surge? Surge protection for industrial UPS systems depends on…
Common Modes of SPD Failure: Warning Signs, Causes, and Prevention
What if a failed SPD is warning you about more than the device itself? The common modes of spd failure include MOV degradation from repeated surges…
