Installation & Application（安装应用） Product Description
NKP-LJ-06Y Lightning Recorder
The NKP-LJ-06Y is a new-type instrument for recording lightning waveforms, using an open-loop Rogowski coil as the sensor to enable non-intrusive installation and save construction costs.
The NKP-LJ-06Y employs STM32F407 as the core processor, with a 12-bit ADC supporting a maximum sampling rate of 2MHz and up to 5,000 sampling points for a single lightning waveform.
It can real-time record various lightning parameters, including the number of strikes, occurrence time, duration, peak current, wavefront direction, energy value, and waveform data.
The NKP-LJ-06Y is standard-equipped with an RS485 communication interface, enabling real-time reading of lightning waveform parameters via the standard Modbus RTU protocol. A Micro SD card is also standard-provided to store each recorded lightning waveform.
