Surge, also called surge, is beyond the normal voltage instantaneous overvoltage, generally refers to the power grid for a short period of time like a "wave" of high voltage caused by the large current. In essence, the surge is a violent pulse that occurs in just one million seconds. So what does surge voltage mean? What are the causes of surge voltage? What are the solutions to surge voltage? Next, let's answer these questions together.
One, what does surge voltage mean?
Circuits are struck by lightning and in the connection, disconnection of inductive loads or large loads often produce a very high operating overvoltage, this transient overvoltage (or overcurrent) is called the surge voltage (or inrush current), is a transient interference.
Two, surge voltage causes?
There are two reasons for the generation of surge voltage, one is lightning, the other is a large load on the grid on or off (including compensation capacitor switching) when generated.
Three, the surge voltage solution
Use of surge protectors, surge protectors are through the discharge of lightning current, limit the surge voltage to protect electronic equipment, is the main means of lightning protection of electronic equipment, but also the main measures of internal lightning protection, thus becoming an important part of the integrated lightning protection system.
Surge protectors are connected in parallel at both ends of the protected equipment to protect electronic equipment by discharging surge current and limiting surge voltage.
