Surge memory

 

Surge memory  

This device counts the peak value and continuous duration of inducted lightning surge current as energy volume, so, with a 10/200μs lightning surge waveform as reference, it can categorize and display three levels, depending on the input current value. Further, it judges waveforms longer than 10/200μs to have more current, and shorter waveforms to have less, and counts based on this judgement.

This device counts the peak value and continuous duration of inducted lightning surge current as energy volume, so, with a 10/200μs lightning surge waveform as reference, it can categorize and display three levels, depending on the input current value. Further, it judges waveforms longer than 10/200μs to have more current, and shorter waveforms to have less, and counts based on this judgement. The unit comprises an external current transformer (CT) and built-in electronic counter housed in a plastic case. The unit’s current comes from a lithium battery built into the electronic counter, making the unit practically maintenance-free.
