A METHOD FOR MEASURING CATHODIC PROTECTION CURRENT

摘要

A method of noncontact measurement of Cathodic Protection Current (CPC) is disclosed. The method includes inline measurement of a magnetic field induced by the CPC. To induce a non-zero magnetic field, an inline magnet is placed next to a wall in a way to produce axially asymmetric magnetic saturation inside a metal. Further, a value of the CPC is determined by using the measured magnetic field.
