What is the primary purpose of using isolating fittings in a cathodic protection system?

To increase current flow
To prevent electrical interference
To isolate different structures
To enhance corrosion resistance

The correct answer is: To isolate different structures

The primary purpose of using isolating fittings in a cathodic protection system is to isolate different structures. Isolating fittings are crucial components that serve to electrically separate segments of a pipeline or other metallic structures. This isolation is essential in cathodic protection systems because it prevents stray current from interfering with the protection of each individual structure. By creating an electrical barrier, isolating fittings ensure that the applied protection current can effectively reach the target structure without being diverted or affected by neighboring pipelines or structures that may have different electrical potentials. This is important not only for the efficiency of the cathodic protection system but also for preventing corrosion and damage to interconnected systems. When isolating fittings are used correctly, they facilitate the targeted application of cathodic protection to specific sections while maintaining the overall integrity and performance of the system.
