In support of the ORNL Advanced Diagnostic Engineering Research and Development Center (ADEC), motor current signature analysis (MCSA) has been used to monitor a variety of motor-driven devices at the Philadelphia Electric Company's Eddystone Generating Station as part of a program conducted by the EPRI M D Center. The purpose of this project is to demonstrate the ability of MCSA to monitor degradation in aging power plant equipment. The focus of this work has been the development and demonstration of an on-line, automated data acquisition system that has, for the last several months, provided motor current signature information on eight motor-operated valves (MOVs) that are a part of the unit 2 turbine steam extraction system. Since October 1989, over 1200 MOV actuations have been recorded and analyzed. The work carried out thus far has resulted in the discovery of undesirable MOV operational characteristics and the identification of other signature trends that will be closely monitored over the next few months. In order to improve data analysis capabilities, an automated data analysis program has been developed that significantly reduced the time required to extract diagnostic information from the MOV motor current signatures. This report provides the results from the analyses of extraction valve motor current signatures that were acquired during the period November 1989 through January 1990 and is thus intended to serve as a companion to the first progress report that covered the month of October 1989. 1 ref., 90 figs., 4 tabs.
