SPDM (switchyard predictive maintenance) surveys will be conducted on all main transformers and support equipment in each switchyard. These surveys will be targeted specifically towards determining the current equipment condition and establishing a baseline database.

Procedures and Guidelines for the following will be enhanced as part of this effort.

• Substation Predictive Maintenance Program Guidelines
• Periodic equipment reports
• Periodic survey reports
• Inspection techniques

Goal: Benchmark/Baseline the condition of the energized, fully loaded main transformers and their support equipment. Virtually eliminate unexpected equipment shutdowns.

Specifically, FSI project team members or its subcontractors and Utility personnel will work together to collect data for analysis to be made by FSI and the Utility. The hands-on training outlined below is intended to allow the Utility personnel to be self sufficient with the data collection and analysis procedures by the completion of the effort.

• Hands-on training of Utility personnel for each of the technologies data collection techniques and development of the SPDM program
• Classroom sessions on technology, diagnostic equipment and technique, as required.

Goal: Transfer technology and technique to Utility personnel; create understanding of what the proper use of and limitations are, for each piece of diagnostic equipment.

• Specific occurrence reports with benefit calculation assessment.
• Default benefit calculation process.

Goal: Demonstrate the switchyard program benefit/value to the Utility.

Report on the value of new on-line instrumentation for transformers, circuit breakers and other substation equipment. This report will include a description of how these new systems can or should be implemented in the SPDM program.

Goal: Evaluate each Generating Stations existing diagnostic test equipment, make recommendations on portable and on-line systems, as required.

Task V - Database Evaluation and Integration

• Recommendations concerning revising preventive maintenance scheduling.
• Recommendations to determine how often to monitor equipment.
• Periodic meeting will be held to discuss progress and future direction.

Goal: Look at existing data, database and reporting techniques. Evaluate the possibility of merging new information into the current system.

Draft outline of data acquisition process for each station.

• Briefing to orient/indoctrinate pertinent work groups.
• Assess existing diagnostic test equipment, make recommendations, as required.
• Evaluate existing software for database entry and reporting.
• Set up parameters for diagnostic equipment, as required.(Alarms/Thresholds)
• Acquire baseline data.
• Field report of energized transformer condition.
• Baseline database on disc.
• Oil quality and DGA results available in one week, Furan results in two weeks.
• Final report, including estimate of transformer remaining life.
