Relay Protection Test Report Format
A relay protection test report typically includes sections for test objectives, relay details, test procedures, measured results, and conclusions.
Suggested Format for a Relay Protection Test Report
1. Report Header
- Report Title (e.g., "Relay Protection Test Report")
- Project/Plant Name
- Relay Manufacturer and Model
- Relay Serial Number
- Date of Test
- Test Engineer(s) Name(s)
- Location of Test 2. Test Objectives
- Purpose of the test (e.g., functional verification, type testing, compliance with standards)
- Scope of testing (e.g., overcurrent, differential, distance, or loss-of-mains protection) 3. Relay Settings
- Name and type of protection function (e.g., 50/51, 21, 27, 32)
- Setpoints (pickup current, time delay, voltage thresholds, frequency limits)
- CT and VT ratios
- Any special configuration or logic applied 4. Test Equipment
- List of test instruments (e.g., relay test sets, current and voltage injection devices)
- Calibration status and accuracy 5. Test Procedure
- Step-by-step description of tests performed, including:
- Current and voltage injection levels
- Phase angles and sequence of injections
- Functional checks (e.g., pickup/drop-off, broken-wire monitoring, trip verification)
- Stability and timing tests
- Reference to standards or guidelines followed (e.g., IEEE, IEC, EREC G99) 6. Test Results
- Measured values vs. expected values
- Trip times, pickup currents, and voltage/frequency responses
- Observations of any anomalies or deviations
- Tables or charts summarizing results for each protection function 7. Sequence of Events (if applicable)
- Event logs or COMTRADE playback results
- Verification of relay logic and interlocks 8. Analysis and Comments
- Assessment of relay performance against specifications
- Recommendations for setting adjustments or further testing
- Notes on any limitations or constraints during testing 9. Conclusion
- Overall evaluation of relay functionality
- Confirmation of compliance with design and standards
- Sign-off by test engineer and reviewer 10. Appendices
- Detailed test data sheets
- Graphs, waveforms, or COMTRADE files
- Calibration certificates of test equipment This format is based on examples from generator relay test reports, type-test verification reports, and differential protection procedures, ensuring that all critical aspects of relay testing are documented clearly and professionally .
