AC Surge Protective Device is an indispensable device for lightning protection of electronic equipment. Its main function is to limit the transient overvoltage that penetrates into power lines and signal transmission lines to the voltage range that the equipment or system can withstand, or to release strong lightning current to the ground, thereby protecting the protected equipment or system from damage .
The AC Surge Protective Device contains at least one non-linear voltage limiting element, the type and structure of which vary depending on the specific application. AC Surge Protective Device plays an important role in lightning protection of electronic equipment, especially in preventing damage to electronic equipment caused by natural phenomena such as lightning.
To sum up, AC Surge Protective Device is a key lightning protection device for electronic equipment, which protects electronic equipment from damage by limiting transient overvoltage and releasing strong lightning current.
A surge protective device (SPD) is designed to protect electrical systems and equipment from surge events by limiting transient voltages and diverting surge currents. Surges can originate externally, most intensely by lightning, or internally by the switching of electrical loads. The sources of these internal surges, which account for 65% of all transients, can include […]
To choose the best technology for surge protective devices, we should consider the following technical parameters (include but not limited to): 1. Type of surge protective devices according to EN61643-11/IEC 61643-11 2. Nominal Voltage (Un) 3. Maximum Continuous Operating Voltage (Uc) /Maximum Continuous Operating Voltage for PV System (Ucpv) 4. Voltage Protection Level (Up) 5. Nominal Discharge Current (In) 6. Maximum Discharge […]
