Earth/Ground Resistance Online Detector/Tester Factory(Non-Explosion proof, Wireless network system)

Description

http://www.sltup.com/Earth-Resistance-Online-Detector-Factory-Price-Non-Explosion-Wireless.html

Earth/Ground Resistance Online Detector/tester using circuit measurement method to measure the ground resistance, installed in the connection between ground lead and vertical ground, monitoring the connection condition of the grounding lead line through the online detecting, or by calculating the equivalent grounding resistance of the whole grounding grid through the grounding resistance value, so as to determine the running status of the grounding grid.

Earth Resistance Online Detector developed by Sunlight company does not change any design structure of the original grounding system, and  adopts on-line monitoring technology such as non-contact measurement, which will not affect the grounding effect and the normal operation of facilities. There is no need for self-test and real-time detection,and The product can be installed and used as a single product, or it can be formed into a wired network system or a wireless network component system. With the support of the system, the data can be stored. Through the curve display of the accumulated data, you can intuitively see the changing trend of the ground grid and detect whether the ground grid is in health conditions or not.

Earth Resistance Online Detector (Non-Explosion proof) wireless transmission modes

---

Wireless network system: Data transmission through Lora wireless communication, by the main communicator (concentrator), GSM/GPRS/4G transceiver module, monitoring software, power adapter, computer, etc., suitable for remote or construction wiring inconvenient site, wireless transmission distance accessibility can cover 5 km under barrier-free conditions, and the factory can meet 1 km of stable communication.

Advantages of Sunlight Earth/Ground Resistance Online Detector/tester (Non-Explosion proof, wireless mode) 

---

Sunlight grounding resistance online monitoring system passes various tests, such as The highest harsh level requirements stipulated by surge, static electricity, pulse group, radiation immunity, power frequency magnetic field immunity, voltage short drop, radio frequency magnetic field conduction harassment, That is  to say, Sunlight Earth/Ground Resistance Online Detector/tester (Explosion proof) can work in a stable strong interference environment. 

also, the product passes the 100 KA lightning surge test. That is to say,  during the actual operation of the product, when 100 KA lightning current pass through, Sunlight Earth/Ground Resistance Online Detector/tester detector works normally.
