APPLICATION OF ADVANCED CURRENT MEASUREMENT CONDITION MONITORING METHOD WITH CENTRALIZED PROTECTION AND CONTROL SOLUTION

In the paper a concept is proposed where current circuit supervision is done in a substation level with new centralized protection system, by utilizing Six Sigma principles. This increases the overall visibility to the system and can be used for optimizing the scheduled testing procedures. The concept is tested based on data gathered from a substation pilot installation during a period of two years. In addition, recommendations are given for applicability of Six Sigma principles for measurement supervision, in terms of required data points and measurement intervals.
