Protective Relay Test Record

A defensible protective relay test record is the primary deliverable of NETA acceptance and maintenance testing — it must capture relay nameplate data, CT and VT ratios, test equipment with calibration traceability, relay settings as-found and as-left, measured test results compared to tolerance, functional test coverage, deficiency findings, safety controls, and dual-signature review. This tool generates that record entirely in the browser. Work through the collapsible sections in order: enter job and equipment information, select the test type (Acceptance per ANSI/NETA ATS-2025, Routine Maintenance per ANSI/NETA MTS-2023, Commissioning, or Emergency) and the applicable standard, document test instruments with calibration dates, NIST traceability, and frequency/waveform notes, then fill in relay and device data including firmware version, settings file name and checksum, and settings revision. The Nameplate section captures manufacturer, model, device number, serial number, TCC number, CT and VT ratios, ground-fault CT ratio, and element ranges. The Relay Settings and Test Data section supports dynamic element entry — add as many ANSI relay elements (50, 51, 46, and others) as the relay requires, each with pickup, time dial, as-found, and as-left columns. The Functional Test Coverage section tracks each tested function with Pass/Fail/N/A status and notes. The Safety section documents LOTO or energized work condition status, energized work permit requirement, arc flash/shock risk assessment reference, and PPE boundaries. The Deficiency Summary captures findings and recommendations. The Review section records technician and reviewer signatures, date, and report revision. Relay Family Templates provide a starting point for common relay types. The record saves to browser localStorage for session persistence, exports to JSON for archiving, imports JSON to reopen a saved record, and prints to PDF. Built to align with ANSI/NETA ATS-2025 and ANSI/NETA MTS-2023 documentation requirements.

A live look at the app you'll launch — every control on the left drives the visualizations on the right in real time.

• 01Complete a NETA-aligned protective relay test record from job header through dual-signature review, following the logical sequence of a relay acceptance or maintenance test
• 02Document test equipment calibration traceability including calibration date, due date, certificate reference, and NIST traceability status for each instrument
• 03Record relay nameplate data, CT and VT ratios, ground-fault CT ratio, and element ranges required to verify that the installed relay matches the coordination study basis
• 04Enter relay element settings as-found and as-left with measured test values and evaluate compliance against manufacturer published tolerance, project specification, or engineering study tolerances
• 05Document safety controls — LOTO status, energized work permit requirement, arc flash and shock risk assessment reference, and PPE boundaries — as a mandatory element of the test record
• 06Capture deficiency findings with recommendations, obtain technician and reviewer signatures, assign a report revision, and export or print the completed record

• —Not a design document, stamped calculation, or approval record.
• —Not a substitute for engineering analysis by a licensed professional.
• —Not an accredited test report — it is a NETA-aligned educational field workflow, and acceptance decisions stay with the responsible test organization.
• —Not a relay setting file and not a coordination study of record.
• —Not connected to live equipment and not a safety device.
