What Is The Significance Of Surge Protector Selection?
What is the significance of surge protector selection? Facing the question of what is the significance of surge protection device selection, we all know that there are many types of surge protective device, which are distinguished and installed according to different installation locations and the withstand voltage capacity of the protection equipment. The significance of surge protector selection First, according to the lightning protection zoning principle of buildings described in IEC62305-4, the junction of LPZ0A or LPZ0B and LPZ1 is an area that may directly face lightning impulse overvoltage. This area should be equipped with a T1-level surge protector with large flow and strong discharge capacity.
What is the significance of surge protector selection? This type of customer usually does not understand the significance of surge protector selection. In fact, it is okay to actively consult. There are still a few people who think that lightning strikes are low-probability events. They are perfunctory in the face of selection, and it is too late to regret when problems arise.
What is the significance of surge protector selection? Between LPZ 1 and LPZ 2, at the entrance of the lightning arrester, at the main distribution box or near sensitive equipment, a T2-level surge protector should be installed for voltage limiting. In the area behind the building's lightning protection zone LPZ2, a T3-level surge protector is installed to protect the precision equipment behind. In this way, a multi-level protection method is adopted to gradually reduce the lightning current invading the power system until it disappears, and finally achieve the purpose of protecting the equipment from lightning damage.
What is the significance of surge protector selection? Why do we still need to consider the voltage withstand capacity of the equipment when selecting a surge protector? Because the surge protector is a high-impedance nonlinear element, each time it discharges a strong lightning current, it will consume itself. After a long time, it is inevitable that degradation and failure will occur. Then, it is best to choose an SPD whose effective protection level is far less than the voltage withstand capacity of the equipment, which can effectively increase the service life of the SPD.
