Surge Protective Devices/SPD for Outdoor Street Lights
Outdoor lights are susceptible to transient spikes caused by lightning strikes that are inductively coupled to the power line. Surges may be caused by direct lightning, indirect lightning, or the shutdown/opening of the main power supply.
In addition to surges, the neutral line voltage may be higher than the specified limit for the luminaire if the high-voltage line touches the low-voltage line, or if the neutral connection is weak or floating. For the purpose of this article, we will focus on surge protection.
These surge voltage transients can damage the LED power supply as well as the LED itself. Due to the sensitive nature of LED lamps, we need to provide overvoltage, overcurrent, and surge protection for LED lighting systems. The most common type of surge protector contains a component called a metal oxide varistor or MOV, which diverts additional voltage & energy away from the device it is protecting. In the case of LED lamps, it will protect the LED driver or the LED itself.
ZGSM provides SPD modules for protection over 10kV-20kV in Class I or Class II luminaires. This protection exists between the neutral phase, neutral ground, and phase ground. We offer these modules built into outdoor luminaires, such as street lights, floodlights, etc.
