...Abstract An alternative method to record the potential shift when performing a coating conductance test outlined in NACE TM0102-02¹ is proposed. This method utilizes an oscilloscope rather than a digital multimeter to capture the potential shift when performing the applied current...

..., and calculating the resistance by dividing the voltage drop by the current ( Figure 6 ). The shape and magnitude of the ripple was measured with a digital storage oscilloscope. Discussion The experiment was designed to determine the effect, if any, of various magnitudes of ripple in CP current on the corrosion...

... by most cathodic protection field personnel. This study was an attempt to verify the existence of positive spiking in DC ripple, and possible results. During the project one hundred cathodic protection (CP)rectifiers were observed and oscilloscope waveforms recorded in Tyler, TX. in Bishop, TX stainless...

... to that from cathodic protection rectifiers. An understanding of these potentials is necessary. This paper discusses the "average” DC pipe-electrolyte potential, the "rms", "maximum” and "minimum" potentials and the actual wave-form from an oscilloscope measurement in field applications. Their uses...
