P37.117: Using Voltage and Current Measurements for Monitoring Asset Conditions
Past EPRI Work on Topic
| Product ID | Title | Description | Published Date |
|---|---|---|---|
| 3002030062 | Evaluation of CCVT Secondary Voltage Recordings During Power System Phenomena | This is a report documenting the results of recording a healthy CCVT’s signals during the occurrence of imposed defects in nearby systems or equipment at EPRI’s 138-kV research substation. The planned 2025–2026 baseline testing and secondary signal recording associated with accelerated aging tests will build upon lessons learned from this effort. | December 2024 |
| 3002027138 | Using Voltages and Currents:Applicable Assets | This report is a review of literature to determine which substation assets are likely candidates for health monitoring using voltage and current signals. The selection of CCVTs/VTs for P37.117’s 2025-2026 evaluation is based in part on the outcomesof this report. | December 2023 |
| TR-100205 | Workshop Proceedings: Failed High-Voltage Instrument Transformers | These workshop proceedings describe utility field failures, identify failure modes, and identify possible mitigation measures associated with high voltage current and potential transformers. The field data from these proceedings may inform failure modes identified in upcoming P37.117 testing. | January 1992 |
| TR-113649 | Proceedings: High Voltage Current Transformers and Bushings: Failure Prediction and Prevention Symposium | These conference proceedings include several reports and papers documenting high voltage Current Transformer (CT) accelerated aging tests sponsored by EPRI, including approach, monitoring techniques, and analysis of failed units. The lessons learned from accelerated aging tests in this space inform approaches to accelerated aging test for other instrument transformers in 2025+ forP37.117. | December 1999 |
