1 ANSI/NETA MTS-2007 AMERICAN NATIONAL STANDARD APPENDIX B FREQUENCY OF MAINTENANCE TESTS an excerpt from the ANSI/NETA Standard for Maintenance Testing Specifications for Power Distribution Equipment and Systems 2007 edition 2007 InterNational Testing Association Approved by American National Standards Institute
2 EQUIPMENT RELIABILITY REQUIREMENT APPENDIX B Frequency of Maintenance Tests NETA recognizes that the ideal maintenance program is reliability-based, unique to each plant and to each piece of equipment. In the absence of this information and in response to requests for a maintenance timetable, NETA s Standards Review Council presents the following time-based maintenance schedule and matrix. One should contact a NETA Accredited Testing Company for a reliability-based evaluation. The following matrix is to be used in conjunction with Appendix B,. Application of the matrix is recognized as a guide only. Specific condition, criticality, and reliability must be determined to correctly apply the matrix. Application of the matrix, along with the culmination of historical testing data and trending, should provide a quality electrical preventive maintenance program. MAINTENANCE FREQUENCY MATRIX EQUIPMENT CONDITION POOR AVERAGE GOOD LOW MEDIUM HIGH
