Data records

  • Annex A.2 of IEEE 1547.1-2020 defines clearing time as the interval from the start of the abnormal condition until the DER ceases to energize the Area EPS, made up of detection time, any adjustable delay, the interposing device operating and arcing time, and the interrupting device time. The trip time, which starts at the leading zero crossing in the first half cycle where the parameter is beyond its limit, can be either a part of the clearing time or equal to it; every normative requirement is expressed as a clearing time.

  • IEEE 1547.1-2020 sets out the test and verification procedures (type, production, interoperability, commissioning and periodic) used to show that distributed energy resource equipment conforms to IEEE 1547-2018. Clause 1.2 applies the procedures to every DER technology. Source: IEEE 1547.1-2020, clause 1.2. Verified 2026-10-24. Record std.ieee-1547-1.scope
  • Annex A of IEEE 1547.1-2020 is normative and defines the test signals used by the type tests, including the meaning of clearing time, the step function used for the voltage trip tests and the rate-limited step used for the frequency trip tests. Source: IEEE 1547.1-2020, clause Annex A. Verified 2026-10-24. Record std.ieee-1547-1.structure.annex-a
  • Clause 8.1.3.4.2 of IEEE 1547.1-2020 lets the Area EPS operator or the AGIR impose specific commissioning tests, witness them, or ask for a record of the tests that were run and their results, and treats commissioning as following completed type, production, design and installation steps. Source: IEEE 1547.1-2020, clause 8.1.3.4.2. Verified 2026-10-24. Record std.ieee-1547-1.structure.area-eps-operator-role
  • Clause 8 of IEEE 1547.1-2020 covers DER evaluations and commissioning tests, the field procedure; a note in clause 4.1 explains that clauses 8 and 9 are deliberately less prescriptive than the type and production test clauses because installations and Area EPS operator practices vary. Clause 8.1 presents its procedures as recommendations, with the evaluations and tests actually run being those that the interconnection requirements of the Area EPS operator call for. Source: IEEE 1547.1-2020, clause 4.1, 8.1. Verified 2026-10-24. Record std.ieee-1547-1.structure.commissioning
  • Clause 8.1.2 of IEEE 1547.1-2020 defines four compliance classes that decide how much verification remains for the field: a DER unit that is fully compliant alone, a DER system of units and supplemental devices type tested together, a partially compliant unit, and a DER composite built from partially compliant components and supplemental devices. The composite class needs a detailed design evaluation, an installation evaluation and commissioning tests confined to the requirements that its supplemental devices affect. Source: IEEE 1547.1-2020, clause 8.1.2. Verified 2026-10-24. Record std.ieee-1547-1.structure.compliance-classes
  • Clause 4.5.4 of IEEE 1547.1-2020 names the data formats for reported results: a secured PDF for written results, CSV files with a checksum for tabular results, and the COMTRADE or PQDIF formats for oscillographic data. Source: IEEE 1547.1-2020, clause 4.5.4. Verified 2026-10-24. Record std.ieee-1547-1.structure.data-formats
  • Clause 8.1.4.1 of IEEE 1547.1-2020 lists the steps required for every DER verification: reviewing the owner's project requirements and the AGIR requirements, determining the reference point of applicability, confirming that the interconnection agreement is executed, verifying every setting against the Area EPS operator's requirements, verifying the operating modes and the abnormal and normal performance categories to be commissioned, checking the settings against the protection study, and listing the elements to be verified at commissioning. Source: IEEE 1547.1-2020, clause 8.1.4.1. Verified 2026-10-24. Record std.ieee-1547-1.structure.design-evaluation-steps
  • Clause 4 of IEEE 1547.1-2020 holds the general requirements shared by all of its tests: the accuracy and tolerance basis for judging performance, the statements the manufacturer must supply, the test source and measurement system requirements, and the content and format of test reports. Source: IEEE 1547.1-2020, clause 4. Verified 2026-10-24. Record std.ieee-1547-1.structure.general-requirements
  • Clause 6 of IEEE 1547.1-2020 holds the interoperability tests: a general procedure for adjustable settings, nameplate, configuration, monitoring and management information tests, and protocol mapping tests for SunSpec Modbus, IEEE 2030.5 and DNP3, each including read and write tests of the voltage trip and frequency trip settings. Source: IEEE 1547.1-2020, clause 6. Verified 2026-10-24. Record std.ieee-1547-1.structure.interoperability-tests
  • Clause 4.6.3 of IEEE 1547.1-2020 ties the measurement system's uncertainty to a fraction of the minimum required measurement accuracy of IEEE 1547-2018 Table 3, requires valid traceable calibration, sets the sampling rate relative to the highest frequency of interest, and defines applicable voltages as RMS values over the preceding fundamental period. Source: IEEE 1547.1-2020, clause 4.6.3. Verified 2026-10-24. Record std.ieee-1547-1.structure.measurement-system
  • IEEE 1547.1-2020 gives no numeric pass band of its own for a trip magnitude or clearing time measured in the field: a type test passes when the unit trips inside the clearing time of IEEE 1547-2018 (clause 5.4.2.4), a production test passes when the unit trips inside the manufacturer's ranges (clause 7.2.3), and the commissioning test of clause 8.2.3.3 is judged against the limits and clearing-time tables of IEEE 1547-2018. Source: IEEE 1547.1-2020, clause 5.4.2.4, 7.2.3, 8.2.3.3. Verified 2026-10-24. Record std.ieee-1547-1.structure.no-field-tolerance
  • Clause 9 of IEEE 1547.1-2020 covers periodic tests, whose purpose is to confirm continued conformance using the clause 8 field methods as agreed. Re-verification is called for when firmware or software changes without being tested, when hardware is modified or replaced with parts that are not substitutes, when protection functions, operating modes or settings are adjusted after commissioning, and when power quality problems appear in the field; the clause names no test interval. Source: IEEE 1547.1-2020, clause 9. Verified 2026-10-24. Record std.ieee-1547-1.structure.periodic-tests
  • Clause 7 of IEEE 1547.1-2020 requires production tests on every unit, run at the factory or as part of commissioning, consisting as applicable of overvoltage, undervoltage, overfrequency and underfrequency trip tests at one set of trip points that the manufacturer specifies. A unit passes when it trips within the ranges the manufacturer specifies, and clause 7.4 lists the documentation to be available on request. Source: IEEE 1547.1-2020, clause 7. Verified 2026-10-24. Record std.ieee-1547-1.structure.production-tests
  • Clause 4.5.5 of IEEE 1547.1-2020 defines a naming convention for reported parameters that joins the parameter name to a data context (technical range, evaluated range, specified range, specified settings or applied setting) and a data type, and Annex B supplies the normative results-reporting template that uses it. Source: IEEE 1547.1-2020, clause 4.5.5, Annex B. Verified 2026-10-24. Record std.ieee-1547-1.structure.settings-naming
  • Clause 4.5.3 of IEEE 1547.1-2020 applies its reporting requirements to type, production and commissioning tests; for installation evaluations and periodic tests, any format the parties agree on that meets clauses 8 and 9 is acceptable. The commissioning summary report, carrying the results and any recommended corrective actions, comes from a person or entity qualified to run or supervise the tests and goes to the Area EPS operator. Source: IEEE 1547.1-2020, clause 4.5.3. Verified 2026-10-24. Record std.ieee-1547-1.structure.test-reports
  • Clause 4.6.1 of IEEE 1547.1-2020 recognizes that its full test source requirements may not be achievable for production and commissioning tests: the manufacturer and the testing laboratory agree acceptable source requirements for production tests, while for commissioning tests the Area EPS operator together with the DER operator (or a representative of either) agree them. Signal injection is permitted where a test allows it, and the report identifies the tests that used injection and the reason. Source: IEEE 1547.1-2020, clause 4.6.1. Verified 2026-10-24. Record std.ieee-1547-1.structure.test-source-by-agreement
  • Clause 5 of IEEE 1547.1-2020 holds the type tests, covering temperature stability, voltage and frequency trip, ride-through, rate of change of frequency, phase-angle change, enter service, synchronization, interconnection integrity, dc injection, unintentional islanding, open phase, current distortion, active power limiting, voltage regulation modes, frequency droop, prioritization, overvoltage contribution, fault current and persistence of settings. Source: IEEE 1547.1-2020, clause 5. Verified 2026-10-24. Record std.ieee-1547-1.structure.type-tests
  • Clause 4.1 of IEEE 1547.1-2020 orders the verification phases: type tests and interoperability tests run by a type testing laboratory on one or more samples, production tests on every unit or supplemental device, a design evaluation that decides which items still need on-site verification, then installation evaluations and commissioning tests carried out on site by qualified personnel, and periodic tests as agreed between the Area EPS operator and the DER operator. Source: IEEE 1547.1-2020, clause 4.1. Verified 2026-10-24. Record std.ieee-1547-1.structure.verification-phases
  • Clause 8.1.4.2 of IEEE 1547.1-2020 selects one of four verification summary tables by compliance class and reference point: Table 72 for PoC units, Table 73 for PoC composites, Table 74 for PCC systems and Table 75 for PCC composites. Each table marks, for every applicable clause of IEEE 1547-2018, whether each design evaluation, installation evaluation and commissioning test is required, dependent on the design evaluation, or not required.
