Designing Cathodic Protection For Power Plant Applications Pdf Deep This document discusses the unique challenges of designing cathodic protection systems for buried piping in power plants. it notes that power plant environments are highly congested underground with many structures that can influence cp system design. maintaining electrical isolation of piping is difficult due to the extensive copper grounding network connecting all above ground structures. The design firm also should be responsible for start up of the cathodic protection system, including the collection and analysis of baseline data and hands on training of plant personnel in periodic maintenance and monitoring procedures.
Figure 1 From Designing Cathodic Protection For Power Plant The cathodic protection current demand is the amount of electricity required to polarize the structure to a level that meets the criteria described in section 4. Recently many such cases were investigated at power plants both coastal and non coastal and based on studies it was identified that these components could be well protected by application of suitable anti corrosive coatings and properly designed cathodic protection systems. accordingly identification of suitable anti corrosive coatings and design & application of cathodic protection systems. The first step in the design of sacrificial anode type cathodic protection systems is the determination of the total current required for the system. this fixes the current to be supplied by the sacrificial anodes. Design and configuration of a semi deep anode groundbed cathodic protection system is based on the required current output and expected geologic condition. it is important to consider all facilities that will be in electrical contact with the cathodic protection system.

Corrosion control systems which relocate these oxidation reactions, by making the protected structure a cathode in a larger corrosion cell, is called a “cathodic” protection system.” the cathodic protection anodes are installed to become the anode in this larger corrosion cell and provide the location for all oxidation reactions in the cell. The designing of cathodic protection systems is rather complex, however, it is based on sim ple electrochemical principles described earlier in chapter 2. corrosion current flows between the local action anodes and cathodes due to the existence of a potential difference between the two (fig. 5.1). as shown in fig. 5.2, electrons released in an anodic reaction are consumed in the cathodic.
