What can be a direct consequence of gas blockage in deep anode beds?

• A. Increased current output
• B. Reduced efficiency of cathodic protection
• C. Higher resistance in the system
• D. Improved corrosion resistance

Answer: (B)

Gas blockage in deep anode beds can lead to a reduced efficiency of cathodic protection systems. When gas collects around anodes, it can create an insulating layer that prevents adequate current flow from the anodes into the surrounding electrolyte, which is essential for protecting the infrastructure from corrosion. This impediment in current distribution diminishes the system's ability to effectively control corrosion, thereby compromising its primary function. As a result, the protective measures intended to inhibit corrosion become less effective, making it crucial for cathodic protection systems to be monitored and maintained to prevent gas buildup around anodes.
