On a midsummer afternoon, the manager of the engineering department of a hotel chain was worried about the third air conditioner motherboard burnout in three months. When we took the portable testing equipment to investigate on-site, we found that the voltage fluctuation peak was as high as 380V – this is a typical accident caused by the lack of a surge protector. This real case confirms the urgent need for professional protection equipment in the current market.
Surge Hazards: The Invisible Killer Hidden in the Socket
What is a surge?
Just like a sudden increase in pressure in a water pipe will burst the pipe, a surge is a sudden increase in voltage. Thunderstorms, the start and stop of high-power electrical appliances, and even the renovation of neighbors can all cause surges.
