Cathodic Protection Training Course
Module 8
Ground beds and resistivities
Ground resistivities
The effect of ground resistivity on cathodic protection systems is misunderstood resulting in poor design and inacccurate analysis of acquired data.
Resistivity measurements
There are many sorts of surveys used to determine the resitivity of the ground through which pipelines pass.
Resistivity effects on corrosion.
There are many effects of ground resistivity on corrosion.
Spread of protective currents.
The resistivity of the ground affects the spread of protective currents.
The effects of resistance on monitoring measurements.
These effects are clear if you have studied Module 01.
Groundbed siting
Stes for groundbeds requires an in depth understanding of all aspects of cathodic protection
Practical work with instruments being compiled.
Several field trips are required to practice chosing ideal sites for cathodic protection ground beds.
On-line real time discussion.
