Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion that may be readily understood.
The embodiment of the application provides a linear anode breakpoint searching method. The linear anode breakpoint lookup method can be applied to the field of safety inspection of buried pipeline facilities, and is exemplified by regional cathodic protection. The linear anode breakpoint searching method can also be applied to cathode protection implemented by buried storage tanks and equipment in fields, stations and libraries.

The regional cathode protection system provided with the linear anode has uniform protection potential distribution and good protection effect, and is widely applied to the regional cathode protection of the station, in particular to the regional cathode protection system of the buried pipeline of the newly built station.
Linear anodes include novel flexible anodes with noble metal oxide and titanium substrate (MMO/Ti) filaments as the anode core. MMO/Ti is formed by coating a titanium substrate with an electrocatalytically active metal oxide coating. The metal oxide coating has little polarization and a particularly low consumption rate. By adjusting the composition of the metal oxide layer, it can be used in different environments. Such as fresh water, sea water, or a soil medium, etc. Noble metal oxides have become the most desirable and promising auxiliary anode materials to date because of their advantages over other anodes.

The broken line is difficult to observe from the outer surface of the anode, the position of the broken point cannot be accurately judged, and the normal operation of the negative protection system is affected.
