Transient surge events, which are extreme bursts of extra energy that last for just a few microseconds, are a significant threat to outdoor lighting systems. Voltage surges can be caused by direct and indirect lightning strikes, electrical discharge switching events, static or electrification . Street lights are susceptible to damage from voltage surges in both the differential and common modes. A differential mode surge occurs between the line-neutral (L-N) and line-line (L-L) terminals of a luminaire. A common mode surge occurs between phase cores to earth (L-G) and neutral core to earth (N-G). Transient voltage protection for street lighting systems is implemented by installing surge protection devices (SPDs) in the main distribution cabinet, the cable junction box, and the luminaire. The energy pulses in common mode surges are generally larger than the energy pulses in differential mode surges. An SPD installed in a luminaire should be preferably a full mode protection device that pro tects the luminaire against both common and differential mode surges with overvoltages up to 20 kV in common mode and 10 kV in differential mode.
