Lightning grounding resistance monitor (GRM)

Product introduction

Due to the short discharge time, large amplitude and high frequency of lightning current, after the storage tank is struck by lightning, the lightning current always passes around the storage tank along the nearest grounding down lead

The local grounding grid is released into the earth. GRM lightning grounding resistance monitor can send out 1.5khz high-frequency pulse micro current to simulate lightning current frequency,

Monitor the impulse grounding resistance of the local grounding grid around the storage tank, and record the lightning current intensity, occurrence time and other parameters during lightning stroke.

Product advantages:

1. Permanent use, one-time installation, long-term use

2. Hot work installation is not required

3. High frequency pulse current, simulating low and medium frequency lightning current waveform

4. Wireless transmission, low communication power, low power consumption, and communication distance greater than 2.5km

5. It has its own lithium battery without wiring, and the service life of the battery is more than 3 years
