Cathodic Protection Training Course

Module 09

Cathodic protection groundbeds.

Groundbeds are designed to inject Direct Current electricity into the ground.
They are connected to the positive terminal of a transformer/rectifier or directly discharge the corrosion current from the base metal which is sacrificed to protect the subject metal.
In either case the ground at the centre of the groundbed is more positive that the surrounding ground. It has a higher electrical potential and will show this on a digital voltmeter.
It is good to be able to imagine a groundbed as a pile of electricity and this can be displayed by a computer using a spreadsheet.
Below are the links to information about Sacrificial anodes, Impressed current anodes, materials, conductors, volts drops, header cables, ring mains, insulation, jointing systems, groundbed potential profile plotting, closeness of anodes, horizontal, vertical, borehole and disused-used oil-wells, Scrap metal groundbeds, Practical bench experiments relating to groundbeds and Field work with survey to locate a groundbed and plot it's profile.
When completed the student will be required to complete a report and engage in an on-line real-time discussion in order to recieve a certificate of understanding and ability.
