Re: cathodic protection calculation

Home Electrical Engineering Forum General Discussion cathodic protection calculation Re: cathodic protection calculation



the calculation of a cathodic protection sytem depends at first to the objet to protect (its material, dimensions, geometry, caoting ), at second of the envirnement (soil, sea, river…).

the envirnement is catactrise with its resistivity, if the resitivity is too low, and if its caot isn't made of lagging, and if its the electrolyt isn't sufuric acid then  you can protect the objet with a system of cathodic protection.


th e calculation depends en the external surface of the objet and ist type of coating.

there's same vlaues isccated in nace standards or  europeen standards that give you grid of values to use in calculation of cathodic protection
