According to the IEC 61643 product standard, multi-level surge protection in low-voltage systems can be divided into different types according to the different application scenarios of surge protectio
In the previous article, the editor introduced the technical characteristics of primary surge protectors. Now let's introduce the technology of varistor surge protectors for secondary protection. Type
Spark gap surge protectors for primary protection must meet the highest requirements in terms of amplitude and specific energy of surge voltage or surge current, since they should protect against dire
Application scenarios of SPD surge protectors,The IEC 61643 product standard divides the applications in which surge protective device are used into low-voltage systems, telecommunications and signal
There are two ways to connect a surge protector: Kevin connection and branch connection. Of the two connection methods, we often use branch connection, connecting the surge protection device to the li
The design of the surge protection concept of the AC system depends on the existing power grid system, etc. These systems can vary according to the grounding design of the transformer providing the po
Some electrical technicians don't know much about surge protectors. They only know that this thing can prevent lightning, and they don't know much about other things. This situation is quite common an
I believe that before readers read this article, they have some understanding of what a surge protector is and its principle and function. However, readers may have some questions about the installati
Surge protectors are important devices for lightning protection inside buildings. They can discharge lightning current to the grounding device as soon as it invades the system, thereby protecting the
In daily life, electricity is an important energy source that we cannot do without. From skyscrapers to electric lights, electricity is needed. However, in the power network, there is a data that is a
In our lives, many different power supply systems have been derived according to different power usage occasions. In addition to the common single-phase system, the power supply system also has a thre
I believe that readers are familiar with surge protectors, which play a pivotal role in our internal lightning protection. However, many readers must be confused about how to choose a suitable surge p
Lightning is a common natural phenomenon in our lives. Although it flashes and disappears in an instant, it contains huge energy. If this huge energy is not protected, it will cause huge damage. In li
When we choose a surge protector, we often see a word---following current. Then many readers will ask: What exactly is this follow-up current and how is it generated? What impact does the follow-up cu
Regarding the selection of surge protectors, I believe that all readers have a preliminary understanding. So after choosing the correct level of surge protector, how do we look at the parameters of th
Wind power generation refers to a power generation method that converts wind energy into electrical energy by rotating blades with wind power. It has low pollution and does not need to consider fuel a
Wind power generation is an increasingly popular topic in the power generation industry and is strongly advocated in the western region of my country. Because wind power generation has no fuel problem
Choosing a suitable surge protector is a rigorous job. When choosing a surge protective device, even if we have the same model, we will find a difference - remote signal. Then some readers may have qu
Energy coordination of surge protectors in lightning protection design. In actual work and production, we often have such a question: How many levels of surge protection device should we install? How
Choosing a suitable surge protector is a rigorous job. When choosing a surge protector, even if the model is the same, we will find a difference - whether it has remote signaling. Then some readers ma
Surge protector is an important part of internal lightning protection. It can discharge the lightning surge that invades the line to the grounding device, thereby protecting the safety of equipment an
Surge protectors are important equipment in internal lightning protection. Under the protection of surge protective device, even if the lightning current of tens of kiloamperes invades the internal li
Surge protector for incoming line and compensation cabinet of low-voltage complete equipment. In the power supply of life, the electricity we need is usually distributed centrally by low-voltage compl
Photovoltaic power generation is a new form of green and environmentally friendly power generation that my country is vigorously promoting. From photovoltaic power plants to solar water heaters, they
