RELAY ANY PU → TESTSET BI2
BO2 is generic ANY PICKUP. Another enabled element may assert it before the element that ultimately trips.

Closed-loop authority
The TESTSET measures the wire, not the relay's private state.
Internal relay trip may request BO1. The authoritative TESTSET trip exists only after BO1 behavior, the virtual trip wire, independent 10 kHz BI sampling, and BI1 acceptance.

07Measured timing and auto-stop
Open-wire invariant: disconnect BO1→BI1 and the relay may trip internally, but the TESTSET must record no external trip and must not trip-auto-stop.
Operator timing semantics
Generic pickup and operated-element timing are intentionally separate.
Element pickup → element trip
The operated element owns its own P→T. A 60 ms representable 50P definite delay remains exactly 60.000 ms in the reference engine.
Relay trip request → TESTSET BI1
BI1 owns the measured external trip time and optional auto-stop. Evidence keeps the contact/input path visible.
Reset and evidence
One reset transaction, one clear re-arm condition.
After BI1 auto-stop, ARVREL shows OUTPUT OFF · FROZEN CAPTURE. One relay RESET drains stale fault-window acquisition, clears relay state once, releases BO1/BO2 and TESTSET BI1/BI2, and reports READY TO RE-ARM only after the modeled postcondition is satisfied. Completed TESTSET timing and trip evidence remain available.
Multi-IED laboratory
Feeder, transformer, and voltage-control workflows stay in one product line.
Feeder protection and closed-loop testing
4I+4V internal injection, live/replay SV, 50/51/67/27/59/59N, external virtual-I/O timing, operation records, and evidence schema 9.
87T / 87T-HS / REF
10-scenario self-test, synchronized HV/LV/neutral internal injection, CT/vector compensation, security logic, and paired-SV live/replay evaluation.
Virtual transformer control and MMS
Simulated transformer plant, 17-position OLTC, authority/interlocks, MMS browse/read, DataSets, reports, and modeled controls that terminate inside the simulator.
Process bus and trust
Visibility, protection authority, and control authority remain distinct.
Live and replay
Npcap live Sampled Values plus PCAP/PCAPNG replay with SCL-assisted identity, mapping, scaling, quality, continuity, and freshness evidence.
Three trust permissions
AllowsMeasurement, AllowsPickup, and AllowsTrip expose why a stream can remain visible while new protection authority is blocked.
Reviewable evidence
Settings fingerprints, source/run identity, timing events, operated-element cause, trust state, topology, frozen capture, and virtual-control outcomes are retained for review.
Bounded claims
Behavioral fidelity is not calibration or certification.
The 1 µs clock, 10 kHz BI sampler, contact behavior, ADC model, and relay delays define a deterministic behavioral laboratory profile. ARVREL does not claim a calibrated commercial test set, a manufacturer-specific relay clone, IEC 61850 conformance, IEC 60255 type testing, commissioning acceptance, or protection-grade hard-real-time performance.
