Performance of High Frequency Switching Type Potentiostat used at Ninghai Sewage Plant

Taking the impressed current cathodic protection practice at Ninghai Sewage Plant for example, this paper introduces the main features and working principle of a new kind of cathodic protection power supply, i.e. high frequency switching type potentiostat. This kind of potenciostat combines advanced digital control technique, high frequency switching technique and modern communication technique, and has the advantages of convenient management and maintenance as well as prominent synthetic functions. It is the development orientation of the power supplies for impressed current cathodic protection.
