Web Tutorial – Surge and Transient Voltage Suppression

A practical, visual walkthrough of how to protect facilities and sensitive electronics from lightning- and switching-induced transients.
The tutorial explains the roles of MOVs, TVS diodes, gas discharge tubes (GDTs), panel-mounted SPDs, point-of-use strips, EMI/RFI filters, ferrites, series-mode protectors, and motor/drive filters—showing where each belongs in a layered strategy and how they work together to reduce let-through voltage and noise.

You’ll learn

• What causes surges and high-frequency “hash” on AC and signal lines
• How each protection device behaves (energy handling, clamp speed, pros/cons)
• How to design a tiered protection stack: service entrance → branch panel → point-of-use → board level
• Installation essentials: short leads, bonding/grounding, filter pairing, and VFD/motor considerations

Who it’s for

Facility managers, electrical contractors, data-center operators, and engineers who need concise, field-ready guidance
to keep equipment cooler, quieter, and more reliable under real-world power disturbances.
