AUTOMATIC CONTROL OF POWERSTATION: Cathodic Protection Systems

The use of impressed current cathodic protection on power station circulating water systems is increasing. This is probably due to the consistently better performance of installations generally and, notably, of present‐day anode materials. With the increase will arise new maintenance problems. In this article the authors describe experimental equipment developed for the automatic control of such cathodic protection systems and fitted on a turbine condenser box at Brighton ‘A’ Power Station. This prototype unit has now been operating for several months, with considerable success.
