Nine technical parameters of lightning arrester manufacturers
1. Nominal voltage
In accordance with the rated voltage of the protected system, in information technology systems this parameter indicates the type of protector that should be selected. It marks the effective value of the AC or DC voltage.
2. Rated voltage
The maximum effective voltage value that can be applied to the designated end of the protector for a long time without causing changes in the characteristics of the protector and activating the protective element.
3. Rated discharge current
The maximum peak impulse current that the protector can withstand when a standard lightning wave with a waveform of 8/20μs is applied to the protector 10 times.
4. Maximum discharge current
The maximum peak impulse current that the protector can withstand when a standard lightning wave with a waveform of 8/20μs is impacted once.
5. Voltage protection level
The maximum value of the protector in the following tests: flashover voltage with a slope of 1KV/μs; residual voltage at the rated discharge current.
6. Response time
Mainly reflected in the action sensitivity and breakdown time of the special protection element in the protector, changes within a certain period of time depend on the slope of du/dt or di/dt
7. Data transfer rate
Indicates how many bit values are transmitted in one second, unit: bps; it is the reference value for the correct selection of lightning protectors in data transmission systems. The data transmission rate of lightning protectors depends on the transmission method of the system.
8. Insertion loss
The voltage ratio before and after the protector is inserted at a given frequency.
9. Return loss
It represents the proportion of the front wave reflected at the protection equipment (reflection point). It is a parameter that directly measures whether the protection equipment is compatible with the system impedance.
