Task-oriented beta.6 guides

Start from the engineering question, not from a feature list.

The current Windows release supports feeder closed-loop testing, process-bus analysis, Transformer Differential internal/external evaluation, AVR/OLTC simulation with laboratory MMS, FAT/SAT preparation, and education/research workflows.

Protection relay

Feeder testing and engineering

First run

Closed-loop TESTSET quick start

Run the source, inspect relay pickup and operated-element timing, verify the external TESTSET binary-input result, then review frozen capture and one-click re-arm.

Settings and evidence

Protection engineering

Review quantities, settings, pickup/dropout, operated-element timing, external TESTSET timing, restraint, reset, and evidence.

External source

Process-bus workflow

Use PCAP or live Sampled Values with identity, mapping, scaling, continuity, quality, complete-window, and trust review.

Transformer and control IEDs

Evaluate the two other first-class workspaces.

Transformer Differential

87T / 87T-HS / REF

Run the deterministic 10-scenario self-test, synchronized HV/LV/neutral internal injection, then paired-SV live/replay when external process-bus behavior belongs to the objective.

AVR / OLTC

Virtual plant and laboratory MMS

Exercise the 17-position OLTC, authority/interlocks, browse/read, DataSets, reports, GI/integrity, and modeled controls that terminate inside the simulator.

Preparation and learning

Use deterministic software evidence before hardware or network variables.

FAT / SAT preparation

Rehearse cause and effect

Use feeder, Transformer, AVR/MMS, and replay evidence to prepare cases without presenting ARVREL as calibrated acceptance equipment.

Education / research

Teach authority and causality

Study signal provenance, timing domains, trust gating, operate/restrain behavior, virtual controls, and reproducible evidence.

Exercises

Repeatable lab modules

Run structured experiments for timing, protection, process bus, Transformer Differential, and AVR/OLTC.

Boundary

Workflow guidance does not expand authority.

ARVREL remains virtual-output behavioral laboratory software. Use approved calibrated equipment and procedures for formal commissioning acceptance, and use live Ethernet only on authorized isolated laboratory networks.
