Five stages from evidence to signed work package
This is the GridAPM workbench walkthrough on synthetic data: evidence intake, the quality gate, agent reasoning, the engineer's sign-off, and the work package that ships. Every screen below is the designed product UI — including one you can try.

The walkthrough
One transformer, end to end
Follow synthetic asset TX-47 · 230/69 kV through the five pipeline stages. The rail beside the screens tracks where you are.
Intake
Approved evidence streams — DGA, partial discharge, SFRA, thermal, inspection records — are read from your systems.
Every record keeps its source, timestamp, and provenance.
A pilot starts with files your team already has: lab DGA exports, PRPD and SFRA test sets, IR imagery, inspection notes. The workbench parses each one and pins its provenance — source system, timestamp, and owner — to the asset record.

What the engineer sees The TX-47 asset header, one provenance chip per source file, and the import queue doing its work.
Correlate & quality gate
Signals are aligned per asset and screened for gaps, unit errors, and stale data before any reasoning starts.
Rejected inputs are logged with the reason they failed the gate.
Before any AI touches the data, the quality gate aligns signals per asset and screens for gaps, unit errors, and stale records. Corrections are applied in the open — here, an IR camera clock drift — and rejections are logged with their reason.

What the engineer sees Gate marks on every source chip: three passed, one corrected, nothing silently accepted.
Agent reasoning
Agents draft a condition assessment, citing each piece of evidence and flagging contradictions instead of hiding them.
Every draft carries its evidence chain and a confidence band.
Agents draft a condition assessment with the evidence chain attached: cited gas values, ratio analysis, and — deliberately — the one signal that disagrees. Contradictions are flagged, never smoothed over, and the draft carries a confidence band.

Chain of evidence
-
DGA — thermal signature
C2H4 58 ppm exceeds the 50 ppm screening limit; CH4 74 ppm. Ratio C2H4/C2H6 = 2.1 → thermal fault 300–700 °C (IEC 60599, T2). Duval Triangle 1 places the 2026-06-30 sample in T2, close to the DT boundary.
-
Thermal — IR scan 2026-06-28
Hot spot 98 °C at the B-phase LV connection, +23 K against the A-phase reference at comparable load (0.82 pu); top-oil 71 °C.
-
SFRA — no bulk winding movement
2026-05-18 sweep vs 2019 baseline: correlation 0.99 below 2 kHz — no indication of core or bulk winding displacement. The 10–200 kHz band deviates (correlation 0.87), consistent with a local connection change rather than winding movement.
- Contradiction flagged
H2 rise also fits partial discharge
H2 148 ppm (limit 80) and C2H2 11 ppm also fit a discharge; PRPD 2026-06-12 shows an emerging pattern at 30°–110° (peak 460 pC). The draft keeps the thermal fault as primary; repeat DGA in 30 d and keep the PD monitor trending to separate the two hypotheses.
Confidence
0.78 — Moderate-high agent/dga-v2.3
Draft recommendation
Re-sample oil in 30 days; keep the PD monitor trending on the HV-B bushing; thermographic follow-up on the B-phase LV connection; inspect and re-torque at the next planned outage.
What the engineer sees The chain of evidence, a flagged contradiction, the confidence band, and the persistent AI-draft ribbon.
EngineerHuman gate
Engineer sign-off
A qualified engineer approves, edits, rejects, or escalates the draft. Nothing ships without a named reviewer.
The decision, the reviewer, and the timestamp enter the audit log.
Stage 4 is the human gate. A named engineer approves, edits, rejects, or escalates the draft — and each decision stamps the append-only audit log. Nothing becomes a recommendation without this signature.

APPROVEDReturned with engineer edits Re-sample window tightened from 30 d to 14 d; draft sent back to the agent to regenerate the task list.
Draft rejected — rationale recorded Gas rise attributed to the June cooling-bank outage already logged for TX-47. No maintenance action; monitoring continues.

Work package & report
Approved decisions become maintenance work packages and audit-ready reports for your CMMS and stakeholders.
Each report traces back to the raw records it was built from.
Approval turns the draft into a work package: a prioritized task list with an outage-window note, ready for CMMS handoff and export as an audit-ready evidence pack.

FAQ
Product tour boundaries
What role does GridAPM play in operations?
GridAPM is decision support: a local-first workbench for controlled transformer APM pilots. Engineers hold final authority — it performs no autonomous control and claims no final diagnostic authority.
Can a pilot start offline?
Yes. Local-first evaluation on approved historical evidence is the default starting point. OpenAI access and any live integrations are separately reviewed and controlled.
What is the main output of a pilot?
A pilot produces evidence packs, reviewer notes, missing-evidence lists, AI draft rationale, and human-approved work-package context — the same artifacts shown in this tour.
Run this walkthrough on your own fleet
A controlled pilot follows these same five stages on your approved records, with your engineers at the gate.
