Surge protection device T1,T2,T3 relative info
1. According to the definition of IEC61643.1 standard: base on the application environment and test requirements, it can be divided into class I test, class II test and class III test, which are identified as "T1", "T2" and "T3". The test waveforms weremaximum impulse current Iimp (10/350μs); In (8/20μs), impulse voltage of 1.2/50μs. The energy difference between T1 and T2 is huge, T1 being hit directly and T2 being affected by the shock wave
2. From the point of view of the product analysis, as to T1, T2 and T3 level lightning protection device can not be used "advantage" and "disadvantage" to distinguish good or bad, because these lightning protection device each with different use. These can be compared according to the environment and energy used. T1 is applied environment LPZ0A or LPZ0B and LPZ1 interface area, used for lightning high incidence area, lightning current intensity is large level I protection. According to the building lightning protection code, Class I buildings should have T1 SPD of no less than 12.5kA (10/350μs), and local laws and regulations will have more stringent requirements, T1 SPD impulse current will be larger, and T2 SPD should not be less than 60kA (8/20μs). The SPD installation of II and III buildings is different.
3. Class T2 and Class T3 should be installed base on the way of gradual weakening of lightning protection energy and the required configuration of insulation and voltage resistance of protection equipment. For example, the T2 class and T3 class SPD can achieve low residual pressure and more effective protection for equipment. These lightning protection devices have different uses, can be configured according to the appropriate situation of lightning protection device
