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.
Circuit breakers are necessary, and many experts need them to prevent circuit fire caused by short circuit current. Miniature circuit breakers are known to protect only from voltage spikes for a short period, whereas the circuit breaker protects overcurrent in the wiring. If there is over-voltage, it can damage the appliance. However, over-voltage will not […]
In modern power systems, the use of direct current (DC) power supplies is becoming increasingly popular, especially in areas such as renewable energy and electric vehicles. With the widespread use of DC power supplies, the risk of overvoltage faced by electrical equipment has also increased. Therefore, DC surge protective devices (SPDs) have become an important tool for […]
How to choose the right surge protector? Choosing the right surge protective device (SPD) and protective circuit breakers involves considering a wide range of parameters related to types of SPDs, circuit breaker arrangements, and risk assessment. Three rules of thumb for choosing surge protection Now that we’ve established that SPDs should be at the heart […]
