    Abstract: Up till now, the local cathodic protection renewal of oil & gas field station can be only designed based on previous experience. Therefore, it may lead to some facilities out of protection and inhomogeneous distribution of potential. What is worse is that it can cause mutual interference with surrounding systems, resulting in the malfunction of the... Show More
