How To Choose Flow Rate When Purchasing Surge Protector
Even a small surge or peak voltage can ultimately destroy or affect the performance of expensive electronic equipment, such as computers, telephones, fax machines, televisions, audio/video equipment, and other household appliances and tools. The widespread use of computer chips has increased the need for surge protection, as these chips are often very sensitive to voltage fluctuations. Therefore, installing a power supply surge protective device is essential, and the selection of surge protector becomes even more important, such as:
surge protection device Current Selection
1) Building Lightning Protection Zoning and Equipotential Bonding Examples
LPZOA: All objects within this zone are susceptible to direct lightning strikes. Therefore, each object can conduct lightning current, and the electromagnetic field in this zone is not attenuated.
LPZOB: All objects within this zone are unlikely to be struck directly by lightning, but the electromagnetic field in this zone is not attenuated.
LPZ1: All objects within this zone are unlikely to be struck directly by lightning. The current flowing to each conductor is further reduced than in LPZOB, and the electromagnetic field in this zone may also be attenuated, depending on shielding measures. LPZ2 (subsequent lightning protection zone) should be introduced if it is necessary to further reduce the conducted current and (or) electromagnetic field. The subsequent lightning protection zone should be selected according to the environment required by the system to be protected.
