Earth/Ground Resistance Online Detector Factory Price China Manufacturer( MiniType,Wireless system)

https://www.sltup.com/Earth-Resistance-Online-Detector-Factory-Price-China-Supplier-Minitype-Wireless.html

Sunlight Earth Resistance Online Detector 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.

Ground 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. 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 (Micro Type, wireless) transmission modes

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.

Sunlight Ground Resistance Online Detector/tester advantages(Micro Type, 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 (Micro Type) 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.

Application of Ground Resistance Online Detector

Suitable for tower grounding of transmission lines; Meteorological lightning protection grounding; Grounding of communication; Grounding of transformer distribution station; Grounding of railway facilities; Grounding of building warehouse; and Electrical equipment grounding.
