What is SPD? Presumably, everyone is familiar with surge protectors (SPDs), also known as lightning arresters (SPDs), which refer to lightning surge currents. When electrical equipment is struck by lightning, there will be a huge induced current. Surge protectors can quickly discharge lightning surge currents into the ground, thereby protecting electrical equipment from lightning strikes. Applicable to the requirements of surge protection in household residential, tertiary industry, and industrial fields, with protection modes such as relative phase, relative ground, relative neutral line, neutral line to ground, and their combinations. So what are the main parameters of surge protective devices (SPD)? And what are the related experiments? Let's learn together with the editor below
Visual inspection method
1. The Social Security Electronic Surge Protection Device (SPD) indicator window displays visual alarms: green indicates normal, and red indicates failure 2. The Social Security Electronic Surge Protection Device (SPD) indicator light is a visual alarm: the light on indicates normal, and the light off indicates failure
