Asset service history search that shows the technician what was done to an asset before they open the box
Know what was done here before you open the box.
See one case, screen by screen ↓Before or during a visit, a technician cannot quickly see what was done to an asset before, which parts were used and what failed. The records exist — work orders, closeout notes, photos, inspections, the asset register — but as forms and free-text fields. On a tablet the technician sees the open work order, not the asset's story, and old closeout notes, photos and the paper cards from before the system change are as good as unsearchable. So the crew cleans the cable box, dries it, resets and leaves, and the fault comes back. On a ring main unit every repeat trip takes every customer downstream off supply.
The cause may already be written down. A crew lead who opened the box properly named the fix in a closeout note, the follow-up job was cancelled, and the next two crews never saw it. When that crew lead retires, the note is the only place the diagnosis survives — and 21% of water utility staff can retire within five years (AWWA, 2025). The same history is also a safety record: a cable box last found wet with tracking, or a survey that heard discharge, is a known hazard. If the next crew does not know, they open it blind.
Estimated split for one investigation visit to a repeat fault, in crew hours, by hand and with the solution.
Six agents turn every past job into one cited life story; the technician decides and the crew lead approves.
Lumina Utilities runs electricity and water networks. RMU-4471, an Arcton SR-3 11 kV ring main unit at Calder Road secondary substation, has tripped on earth fault on Way 2 three summers running, each time taking off the 312 customers on the Harbour Lane ring. On Tuesday 13 October 2026, Tomás Reyes is sent to investigate. Here is his day, screen by screen, in the working solution.
Priya builds Tomás's route for van V-217: RMU-4471 at 08:30, TX-2290 at 13:45, LVP-0815 at 15:00 and RMU-3318 at 16:15. Each job's history is read by 06:00 and cached on the tablet. The van list is built from the parts each past job used or named: the termination kit is loaded; the 63 mm gland, breather and heater for RMU-4471, a gasket kit for TX-2290 and anti-tamper bolts for LVP-0815 are at Calder depot.
“Bushing gasket kit, 200 kVA GK-200 · TX-2290 · named 2023, never ordered”
At Calder Road secondary substation, CRD-S12, Tomás points the tablet at the tag. It reads RMU-4471 and matches it to one asset in the register, including the ID it carried before the 2014 system change, CR-S12/RMU1. Today's job is WO-2026-088391, raised by Helen Marsh: “Investigate repeat earth fault, Way 2 cable box”, with a planned outage from 09:00 to 13:00.
Tag and asset resolver: never guesses between two assets — if two could match, it asks.
The life story comes back: 19 events from 14 records and 23 photos, 2009 to 2026, in five lanes — installs and jobs, faults, repairs, tests and inspections, parts. Commissioned 14 Mar 2009. A 2021 inspection found the ground round the plinth wet. A June 2023 partial-discharge survey heard 14 dB ultrasonic at the Way 2 cable box: “Monitor, resurvey in 12 months.” It was never resurveyed. The pattern finder joins the three faults with a red band.
“Repeat found: 3 earth-fault trips · every one between June and August · all on the Way 2 cable box” — 383 and 343 days apart, 148,200 customer minutes lost.
Fold by season redraws the timeline as years stacked over a single January-to-December line. The trips of 22 Jul 2024, 9 Aug 2025 and 18 Jul 2026 fall in the same summer column. A work-order list never shows it this way, and it is the view that turns three call-outs into one pattern.
“all 3 trips fall here”
After the first trip, Daniel Mensah's crew re-terminated the Way 2 red phase and found the gland split. The record opens as it was written — crew, times, fault code EF-W2, the photos of the split gland and the tracking — with the quoted passage highlighted. The follow-up job, WO-2024-118377, was cancelled on 30 Sep 2024 as “merged with planned maintenance”. Since then, crews have dried the box and reset it.
“Gland on the Way 2 cable box is split and water is getting in round the cable. Box wet inside, tracking on the red phase. Replace the cable box gland and fit a new breather. No 63 mm gland on the van.”
Water through the split Way 2 gland ranks High, on 5 records. A dead anti-condensation heater, found in March 2025, ranks Medium. Termination workmanship ranks Low: Way 2 was re-terminated in 2024 and tripped again 383 days later. Tomás asks whether the gland and heater fix worked on other Arcton SR-3 units: nine had a wet cable box, all nine had gland CG-63-BR and heater ACH-50W fitted between 2022 and 2024, and none has tripped since, over at least 24 months each.
“RMU-4471 is the tenth with the same story, and the only one where the gland job was cancelled.”
Four hazards from past visits: the Way 2 cable box found wet with tracking on the red phase in July 2026; discharge heard at this box in 2023; SF6 last read 1.29 bar on 18 Nov 2025, so check the gauge before operating; standing water at the plinth after rain. Beside them, the past fixes and how long each held — 383 days, 343 days, 87 days so far — and the two that were never done.
“Prove dead and earth Way 2 to approved procedure ODP-11-07 before opening, under switching schedule SS-26-4471. Switching is by control.”
The gland CG-63-BR, breather SGB-40 and heater ACH-50W are not on van V-217; Calder depot has 4, 6 and 2. Tomás reserves the three for job WO-2026-088391, to collect before 09:00. Aisha Karim approves at 08:43, and they are ready at the depot trade counter.
“The agent reserves; it never orders. Nothing leaves the store until the crew lead approves.”
Tomás speaks his closeout at the substation, 2 min 14 s: the gland was split, “like Daniel said”; he fitted a new 63 mm brass gland and breather; the heater had no supply because the auxiliary fuse had gone, so he replaced both; the termination is sound. The closeout writer drafts cause, work done, parts fitted and readings after — IR 12 GΩ at 5 kV, PD ultrasonic 0 dB, TEV 7 dB, SF6 1.30 bar — and asks for the one reading that was missing.
Asked for: “Heater current after the fix?” — Tomás: “Heater drawing 0.22 amps.”
Tomás signs WO-2026-088391 as the technician who did the work. The life story gains a new event — 13 Oct 2026, gland, breather and heater replaced — and the 2024 recommendation and the cancelled job WO-2024-118377 are closed. The repeat is marked “fix fitted today, watch next summer”; the pattern finder checks it again after 31 Aug 2027.
Only the technician who did the work signs the closeout.
The same asset, seen by the five people who work on it — what their day looked like, and what it looks like now.
Six agents turn every past job into one cited life story; the technician decides and the crew lead approves.
Reads the scanned tag, QR code or typed name and finds the one asset it means in the register, including the IDs used before the 2014 system change.
Reads every work order, closeout note, photo and inspection for the asset and its connected parts, and builds the life story, each event with its date, who did it and the record.
Finds repeats — the same fault on the same part in the same season, in different years — draws the band on the timeline and the season fold, and flags a fix named in a crew note whose follow-up job was cancelled.
Ranks the likely causes by the records behind them, counts how many days each past fix held, finds where the same fix worked on sister units of the same model, and lists the hazards past crews recorded, each with its record.
Lists the parts fitted or named on past jobs, with their stock codes, and checks the van first, then the depots in the order set in Settings.
Turns the technician's spoken closeout into a record — cause, work done, parts, readings and photos — asks for any reading the history says should be proved, and links it to the recommendation it closes.
Decides on site; crew lead approves plan and parts. The agents propose; a named person decides.
Ask about any asset, electricity or water, or say what to do with what you find. Every sentence carries the record it came from; with no record, there is no sentence.
What should I check before opening the Way 2 cable box?
Four things from past visits on RMU-4471. The Way 2 box was wet with tracking on the red phase on 18 Jul 2026. A 2023 survey heard discharge at this box. SF6 last read 1.29 bar, so check the gauge before operating. Water stands at the plinth after rain. Prove dead and earth Way 2 to ODP-11-07 under schedule SS-26-4471; switching is by control.
Has the gland and heater fix worked on other SR-3 units?
Yes. Nine other Arcton SR-3 units had a wet cable box and had the gland and heater replaced between 2022 and 2024. None has tripped since, over at least 24 months each.
Reserve the parts from the 2024 note at Calder depot
Reserved at Calder depot for job WO-2026-088391: gland CG-63-BR, breather SGB-40 and heater ACH-50W, the parts named in 2024 and 2025. I have sent them to Aisha Karim to approve; nothing leaves the store until she does.
Which other assets on my patch repeat every summer?
Eight assets have 3 or more faults between June and August. Two are on your patch besides RMU-4471: RMU-2264 at Station Road and RMU-5120 at Quarry Hill, and both have a fix named in a crew note that was never done.

Software that answers questions on any asset's past jobs for field technicians. Asset Service History Search turns work orders, closeout notes, photos, inspections and the asset register into one cited life story per asset, so the technician knows what was done before, what failed and what fixed it, before opening the box.
The technician scans the tag, or types or asks about the asset. Agents resolve the tag to one asset, read its records into a timeline, find any repeat pattern, rank the likely causes and show how long past fixes held, check the parts against the van and list known hazards. Every line opens the record it came from; the technician decides what to do.
Yes. The same life story works for pumps, valves, hydrants and boreholes as for ring main units and transformers. In the sample, Pump 2 at Westmere pumping station shows four summer bearing-temperature trips and the 2024 note that named high-temperature grease.
The pattern finder groups faults by asset, part and season. By default a repeat needs at least 3 faults on the same part, in the same 3-month window, in different years, looking back 10 years. It also flags a fix named in a crew note whose follow-up job was cancelled or never raised.
Yes. It reads scanned paper cards from before the work management system, and the tag and asset resolver matches assets to the IDs they carried before a system change, so a unit's early history is on the same timeline.
No. It never gives switching, isolation or earthing steps. It lists the hazards past crews recorded, each with its record, and ends with the approved procedure and switching schedule for the job.
Yes. The technician decides on site, the crew lead approves changes to the work plan and every parts reservation, and the asset engineer decides on replacement. Agents reserve parts but never order, draft closeouts but never close a job, and only the technician who did the work signs.
