Surge Protection
Surge protection refers to devices and systems that protect electrical equipment from sudden spikes in power that could damage or destroy them. Think of it like a safety shield for electrical equipment. When there's a lightning strike or power fluctuation, these devices catch the extra electricity before it can harm expensive equipment. This is an important skill for electrical technicians because businesses and homeowners rely on surge protection to keep their valuable electronics and equipment safe. Related terms you might see include "surge suppressor," "surge arrestor," or "TVSS" (Transient Voltage Surge Suppressor).
