- Protective Relay Element Tests is specified for electromechanical and solid-state protective relays in maintenance testing at clause 7.9.1.B.2 of ANSI/NETA MTS-2023. Value: electromechanical and solid-state protective relays.
- Protective Relay Element Tests is addressed in ANSI/NETA ATS-2025.
- Protective Relay Element Tests is addressed in ANSI/NETA MTS-2023.
- Protective Relay Element Tests is addressed in FAA AC 150/5345-10H.
- Protective Relay Element Tests is addressed in IEEE 946-2020.
- The criteria for commissioning test CT3 in clause 8.2.3.3 of IEEE 1547.1-2020 are the limits of IEEE 1547-2018 and its clearing-time tables for the applicable abnormal performance category, applied as defaults unless the Area EPS operator specifies otherwise; a prerequisite is that the installation evaluation has already confirmed the settings that the AGIR or the Area EPS operator requires.
- Commissioning test CT3 in clause 8.2.3.3 of IEEE 1547.1-2020 verifies cease to energize for undervoltage, overvoltage, underfrequency and overfrequency, each at the magnitude and clearing time that IEEE 1547-2018 and the AGIR specify, with the procedure being whatever the Area EPS operator requires and the details settled by mutual agreement. The clause observes that field tests of the abnormal voltage and frequency responses are complicated, so those responses are usually verified by type test, and it allows signal injection on a unit that has provisions for it.
- Clause 8.2.3 of IEEE 1547.1-2020 makes verification of the DER's voltage and frequency tripping functions and of its cease-to-energize behavior mandatory at commissioning, and it allows signal injection where actual adjustment of the voltage and frequency is impractical.
- Table 72 of IEEE 1547.1-2020 shows that, for a fully compliant PoC unit, the mandatory voltage tripping requirement of IEEE 1547-2018 is verified through the design evaluations and the applied-settings read-back rather than through a field trip test, while a field frequency trip test depends on the outcome of the design evaluation.
- The production trip tests in clauses 7.2.2 and 7.3.2 of IEEE 1547.1-2020 connect the unit per the manufacturer, apply and record the manufacturer's trip and time settings with other settings at factory values, select one function at a time, move the source beyond the setting by a margin tied to the minimum required measurement accuracy so that only the selected function causes the trip, record the RMS magnitude or frequency and the clearing time, drive each phase in turn on multiphase units, and repeat for every function.
- The test method is named Protective Relay Element Tests. Value: Protective Relay Element Tests.
