-A surge is a sudden spike in voltage caused by lightning, power-line disturbances, or other electrical events. While it is impossible to prevent surges from occurring, it is possible to protect equipment from the damage they can cause.+Sometimes you may hear someone say, "The PC keeps freezing whenever it rains," or "Equipment suddenly stopped working after a thunderstorm." In many cases, a surge may be the cause.
  
-An SPD (Surge Protection Device) is designed for this purpose. When a surge enters the power line, the SPD redirects the excess energy to ground, helping to protect the connected equipment.+A surge is a sudden burst of electrical energy caused by lightning, electrical switching, or other unpredictable events. Just as we cannot stop lightning from occurring, we cannot completely prevent surges from happening. 
 + 
 +Instead, we protect our equipment from them.

-SPDs are typically installed at the power input of a control panel or electrical system. A proper ground connection is essential, as the surge energy must have a safe path to flow away from the equipment.+An SPD (Surge Protection Device) is installed at the power input and provides a path for surge energy to escape safely to ground. When a surge arrives, the SPD helps divert it away from the equipment. 
 + 
 +Proper grounding is essential. Without a ground connection, the surge has nowhere to go.
  
-You can think of an SPD as a lightning rod for your electrical system. It cannot stop a surge from occurring, but it can help prevent the surge from damaging your equipment.+You can think of an SPD as a lightning rod for your electrical system. It does not prevent surges, but it can help keep them from damaging your equipment.
