DC Surge Protection Device ( DC SPD) is designed to limit transient over voltages of atmospheric origin and divert current waves to earth, so as to limit the amplitude of this over voltage to a value that is not hazardous for the electrical installation and electric switchgear. Type 2 DC Surge Protection Device ( DC SPD): […]
In lightning protection products, surge protectors and arresters are widely used. Both are important components to protect electronic equipment. There are also fundamental differences. Let us first see what these two lightning protection products are. The surge protector is to limit the instantaneous overvoltage that enters the power line and signal transmission line within the voltage range […]
Surge protection devices (SPD) and surge arresters have the same function: they can protect electrical equipment from overvoltage conditions, but what is the difference between them? The following is a brief description of the differences between them. 1. Different Rated Voltages: According to NEC 2017 Sec 280 & 285, the rated voltage of the surge […]
