| Abstract: | The potential remote measurement for high pressure natural gas piping in Shanghai was described in this article.The system structure,configuration and function of remote control data transmit system,which is designed based on micro-consumption electronic technology,was introduced.By using this telemetry system,the piping ground potential disturbed by stray current is measured and analyzed.It has been shown from practice that using this system for real-time monitoring stray current is prominently effective,thus,it is applicable to stray current disturbed potential of natural gas piping. |
