The Automation Paradox: Why Smarter Factories Are More Sensitive to Sags

The denser a factory's automation, the more one voltage sag can halt the whole line. Here's why, and how battery-free TSP protection changes the equation.

What LV-Only Means: Where a Voltage Sag Protector Actually Goes

A voltage sag protector for LV (≤1kV) systems installs in front of the sensitive load, not the utility incoming point. Here is where TSP actually goes and why.

The 10-Year No-Replacement Math: How Storage Design Life Changes TCO

Battery-based voltage sag protectors require periodic replacement cycles, while EDLC-based, battery-free WESCO TSP is built around a 10-year storage design life, structurally changing the maintenance math behind TCO.

Sizing a Voltage Sag Protector: It Starts with a Load Survey

TSP capacity should be sized around the loads that actually need protection, not total incoming power. This article covers load survey, capacity calculation, and installation placement, plus the risks of over- and under-sizing.

0.1 Seconds on an Automotive Line: When Welding and Paint Shops Trip on a Sag

A sag under 0.1s trips robot controllers and PLCs on automotive welding and paint lines. Why restart outlasts the sag, and how battery-free TSP prevents it.
