2 Frequency of Maintenance Tests Appendix B from MTS-01 NETA Maintenance Testing Specifications for Electrical Power Distribution Equipment and Systems 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 Full-Member company for a reliability-based evaluation. The following matrix is to be used in conjunction with NETA s Frequency of Maintenance Tests table. 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 EQUIPMENT RELIABILITY REQUIREMENT MEDIUM HIGH
