Industrial Surge Protection Device: 7 Ways Surges Damage Plants
Most plant engineers discover surge damage only after a drive fails or a production line stops, because transients rarely announce themselves. This article sets out seven specific ways surges damage industrial equipment and shows where an industrial surge protection device interrupts each failure path. It covers IGBT module destruction in variable frequency drives and servo drives, PLC logic corruption and I/O card burnout, motor winding insulation breakdown from repeated transients, sensor drift and dead 4-20 mA loop channels, SCADA data loss and corrupted batch records, cascading failure through switch-mode power supplies and UPS units, and the cumulative degradation that shortens equipment life without any visible fault. The article then traces damage back to its sources in lightning, switching operations and load transients, and explains how coordinated protection stops each mechanism.
