Note: The difference between T1 type and T2 type surge protector

The T1 type surge protector refers to the product with the lightning test waveform of 10/350us, and the T2 type surge protector refers to the product with the lightning test waveform of 8/20us.

The main difference between the two types of surge protectors lies in the different test waveforms. The energy of the 10/350us waveform is stronger than the energy of the 8/20us waveform, so in many cases the T1 surge protector is generally 12.5kA, 15kA, 25kA, etc. , T2 surge protector does have 20kA, 40kA, 60KA, 100kA, etc. Although the value of T2 type surge protector looks larger, their test waveforms are different. In fact, the energy of T1 is stronger.

Therefore, the national standard GB50057-2010 requires the installation of a T1 type surge protector in the main incoming line, which is also the first-level surge protector. When selecting the type, pay attention to the surge protector must have a T1 test Iimp (10/350us) test This parameter is generally Iimp is greater than or equal to 12.5kA, and the protection level Up≤2.5kV is enough.

Tip: Lightning protection is probabilistic protection, and we cannot provide 100% protection.

First, lightning discharge itself has a certain degree of randomness, and lightning parameters have certain statistical properties, which determines that all protective measures based on these statistical characteristics of lightning parameters cannot provide 100% protection. Such as: direct lightning protection-shielding characteristics; lightning current amplitude, waveform, etc. have statistical properties;
Second, the lightning protection equipment cannot prevent the formation of lightning flashes;
Third, lightning protection devices cannot ideally eliminate all interference voltages/currents. The fundamental purpose of taking protective measures is to ensure that most of the energy caused by interference does not spread to the vulnerable parts of the device and the staff.
Finally, the cost of protection against high-level surges with a small probability of occurrence has risen sharply.
