At normal operating voltages, the SPDs are in a high impedance state and do not affect the system. When a transient voltage occurs on the circuit, the SPD moves into a state of conduction (or low impedance) and diverts the transient energy and current back to its source or ground. This limits or clamps the voltage amplitude to a safer level. After the transient is diverted, the SPD automatically resets back to its high impedance state.\r\n\r\n<strong>What Sets the Two Systems Apart?<\/strong>\r\n\r\nOn a basic level, the lightning protection system protects the facility and structure from direct strikes, while SPDs protect electrical equipment and systems against surges or transients.\r\n\r\nHow the two operate, and the components involved, also vary.
