According to published weather data for the year 2019, 2.35 billion lightning strikes were recorded across the world, with 223 million of these in the United States. The movement of atmosphere causes electrical charges to build up between clouds. A tipping point is reached where the insulating properties of the air cannot withstand the level of energy and a discharge occurs.
Surge Protective Devices (SPD), formerly known as Transient Voltage Surge Suppressors (TVSS) have been around for a long time. The most recognized version is integrated into outlet strips and used to protect sensitive electronics from surges, or higher than expected voltages on the power line. Early versions of these surge strips were known to have problems where internal components could overheat and cause a fire. Thermal protection was added to the designs to greatly reduce the potential for a fire hazard. Such an implementation in an outlet strip is considered a Type 3 SPD. Read More
