ElecTwin® replaces the clipboard. Your survey team captures every nameplate, setting, cable run and panel on a tablet, against templates built for power system modelling, with photographs attached and each asset tagged where it stands. It works with no network at all · substation basements included · and publishes a structured model that ETAP, SKM, CYME and EasyPower take straight in.
Every power system study · arc flash, short circuit, load flow, protection coordination · begins with someone walking a plant and writing on paper. That walk is where the schedule slips, where the errors enter, and where the cost actually sits. ElecTwin is built for that walk and for what happens to the data afterwards.
Templates per equipment class, built from what a power system model actually needs rather than a generic inspection checklist. Photograph, tag, GPS stamp and validate at the panel, on a tablet, with no signal.
A missing %Z, a transformer with no secondary voltage, a feeder with no parent bus · flagged while the engineer is still standing in front of the panel, not three weeks later when the model will not converge.
A structured, connected electrical network that ETAP, SKM, CYME and EasyPower ingest directly. And it stays alive afterwards, so the next survey is a delta rather than a repeat of the whole exercise.
Data collection and modelling routinely take more effort than the study itself.
This is not our opinion, it is the consensus of the people who sell these studies. Published industry guidance puts field data collection and scheduling at one to two weeks, engineering and modelling at one to two weeks, and the report and labels at three to five days · then adds another one to two weeks of slippage caused by out-of-date diagrams, missing breaker settings and equipment nobody can get into. The calculation is the fastest part of the whole project.
Drawn from published arc flash study guidance from independent engineering practices, 2026.Data is written by hand at the panel, then typed into a spreadsheet days later by someone who was not there. Every transposed digit survives all the way into the incident energy result, and nothing downstream will catch it.
Faded, painted over, or facing a wall with 200 mm of clearance. The engineer writes “check later”, and later never comes. The bus gets a default value and nobody records that it was a default.
The model will not converge, three fields are missing, and the plant is four hundred kilometres away with a shutdown window that closed last Tuesday. This single event is the most common reason a study slips a month.
The pattern behind all three is the same. The data is validated at the wrong time, in the wrong place, by the wrong person. ElecTwin moves validation to the moment and place of capture, which is the only point at which a gap is cheap to close.
Tell us the site, the approximate bus count and which package the model has to land in. We will tell you what the capture would look like and how many field days it should take.
This is the difference between ElecTwin and a generic forms tool. Fifteen component classes, each carrying exactly the fields a power system study consumes, in the order an engineer actually reads a panel, with the mandatory ones enforced before the record can be closed.
| Equipment class | Captured fields | Enforced before close |

This is the capture screen as the surveyor sees it. Utility, generator, bus, bus duct, transformer, cable, fuse, contactor, HV and LV circuit breaker, switch, relay, motor, load and capacitor · each with a live count of what has been captured and what state it is in.
Note that HV and LV breakers are separate classes, that bus duct is its own type, and that contactor sits beside fuse. That granularity is not cosmetic · it is what stops a surveyor forcing a component into the wrong template and producing a model that will not grade.
Counts update as the team works. A survey manager opening this screen can see the shape of the capture without asking anyone for a status.
Templates are configurable per project, because a distribution utility survey and a chemical plant survey do not want the same fields. What is not configurable is that a mandatory field cannot be skipped silently · it is either filled, or it is recorded as a declared gap with a reason and a photograph, which is a very different thing from a blank cell in a spreadsheet.
This is not a degraded mode or a sync-later compromise. The app is built to run an entire survey campaign with the device in flight mode, because that is the normal condition of the places this work happens: LT rooms below grade, switchyards inside steel structures, plants that do not permit a cellular device on the floor at all.
Templates, validation, the growing single-line, search across what the team has already captured, photographs at full resolution. None of it asks for a network.
The queue uploads in order over whatever it gets · hotel wifi, a phone hotspot, the site office in the morning. Interrupted uploads resume rather than restart.
Three engineers can work three areas of the same plant on three tablets. Each holds its own portion, and the merge happens server-side against the asset hierarchy rather than by someone reconciling spreadsheets on a Sunday.
That is the app's own description, and it is the whole product in one line. Install it on any Android tablet or phone your survey team already carries, sign in, and capture against your templates · in a switchyard, in a basement LT room, in a plant that does not allow a connected device on the floor.
There is nothing to procure and no hardware to specify. The devices your engineers are holding today are the devices this runs on.
Downloading it is free and tells you in ten minutes whether the capture flow suits how your engineers actually work. Templates are configured per project, so what you see on a first install is the standard set rather than yours · tell us your conventions and we will shape it to them.
Every component carries a state from the moment it is captured to the moment it is signed off. This is what separates a survey tool from a forms app: the data has a lifecycle, a reviewer, and a way back when something is wrong.
Saved locally on the device and waiting to be submitted. Editable by the surveyor until it goes up.
Saved without its source component selected. Still editable, but flagged as incomplete until the source is set.
Sent up and awaiting approval. The surveyor can no longer change it; the reviewer can see it.
Accepted by the reviewer. Locked from editing, open for viewing. This is data the model can be built on.
Sent back. The reviewer has flagged something that has to be looked at again, with the reason on the component.
Captured by a different surveyor on the same project. Visible to you, and selectable as the source component for what you are capturing.
The red state is the one worth dwelling on. Every other survey method discovers a bad record when the model refuses to converge, by which point the plant is four hundred kilometres away and the shutdown window has closed. A re-survey flag raised the same week costs an hour.
One substation, your templates, your reviewer in the approval seat. You will know within a day whether the states match how your team actually signs work off.
A number typed into a spreadsheet is an assertion. A number with the nameplate it was read from attached is evidence · and six months later, when the model disagrees with the plant, that is the difference between an argument and a two-minute check.
Nameplate, relay setting sheet, breaker dial, panel front, cable marking. Each image is attached to the specific asset and the specific field it evidences, not dumped into a folder named after the site.
Where the plate is faded, painted or inaccessible, the surveyor records what is legible, photographs it, and marks the remainder as a declared gap with a reason. The gap travels into the model as a flagged assumption rather than a silent default.
The engineer building the model opens the photograph beside the field. Most queries that would have triggered a phone call, or a second trip, are settled from the desk.
ElecTwin does not compete with your analysis package and does not ask you to change it. It solves the step before it · producing a clean, connected, validated network that the package can ingest without a week of manual entry.
Structured export for the Excel and Access data interface, which ETAP imports with any layout and field naming, runs consistency checks on, and can use to generate the one-line automatically.
Component and connectivity export shaped for the import path, so buses, branches and device settings land as objects rather than as a document to re-key.
Network and equipment export for distribution and industrial models, with the source and feeder topology preserved.
Equipment schedules and connectivity in the structure the model builder expects.
Excel, CSV and JSON against a published schema, plus a REST API. If your team has its own toolchain, it reads the same data we do.
Equipment schedules, cable schedules, the asset register and a survey report pack · generated, not retyped.
Where a package offers no documented import route for a given object type, we say so rather than implying a connector exists. The honest position is that ElecTwin removes the data collection and data entry burden from your study, and the last mile into any given package is scoped openly at proposal stage.
ETAP, SKM, CYME, EasyPower or something in-house · we will show you exactly what lands in it and what still needs an engineer's hand.
Most electrical data collection is treated as a one-off cost against a one-off study. Three years later the study is stale, nobody trusts the single-line, and the whole exercise is repeated at full price. That is the cycle this module exists to break.
A survey is a photograph. A twin is a record that stays true.
Once captured, the electrical network lives as a structured asset model · every device, every setting, every connection, with its evidence attached. When a transformer is replaced, a relay is re-set or a feeder is added, that single change is updated rather than the plant being re-walked. The next study starts from a current model, and the re-survey scope is the delta, not the site.
Because the expensive half of it is already done, and done to a standard you can audit. This is the argument that makes the first capture pay for itself.
An electrical modification that alters fault level or protection grading is flagged against the model at the time it happens, instead of being discovered at the next audit.
The electrical network resolves against the same asset register as the machines, so a motor is one asset with both a mechanical and an electrical identity rather than two records in two departments.
Practices selling arc flash, protection coordination and load flow studies, where field data collection is the least profitable and most schedule-destroying part of every engagement.
Multi-plant Indian manufacturers whose single-lines are out of date, whose last study is years old, and who are asked for electrical safety evidence during customer and statutory audits.
Network operators and distribution licensees running asset surveys across substations and feeders, where the field teams are large, geographically spread and working well outside network coverage.
A single-plant capture typically runs a fortnight end to end, most of which is the field days themselves. Nothing here requires a shutdown that the survey would not have needed anyway.
Equipment classes, mandatory fields, the naming convention and the target package are agreed before anyone goes to site. Half a day, done remotely.
Tablets, offline, area by area. Each asset captured, photographed, connected to its parent and validated at the panel. Progress visible centrally whenever a device finds a connection.
Records from every surveyor merge against the hierarchy. Conflicts and declared gaps are listed for decision, and anything needing a second look is identified while the team is still on site.
The connected network exports to ETAP, SKM, CYME, EasyPower or open formats, along with the equipment schedules, cable schedules and photograph archive. The model then stays live for the next change.
Nobody should roll this out across a group on the strength of a demonstration. Every entry point below ends with something real in your hands.
We configure the templates to your conventions and capture a single substation or one MCC room with your engineer alongside ours.
The complete electrical network of a single plant, from the incomer to the last distribution board, delivered as a model and an asset register.
For consultants and EPCs who want their own engineers capturing with it on their own projects, under their own templates and branding.
The register the electrical network resolves against, so a motor carries one identity across both the mechanical and the electrical world.
Where the static model meets live measurement · the captured network becomes the map that incoming energy and load readings resolve onto.
Consumption by feeder, machine and shift against the state tariff, structured by the distribution network ElecTwin captured.
Evidence packs with provenance for statutory and customer audits, including the electrical safety records that come out of the study.
The same field-capture discipline applied to routine inspection rounds once the register exists.
The wider programme this sits inside, for plants taking the whole journey rather than a single survey.
These are the questions electrical consultants, plant engineers and survey managers actually put to us. Where the honest answer is “no”, it says so.
Tell us the site, the approximate bus count and the package your model has to land in. We will configure the templates to your conventions, capture with your engineer alongside ours, and hand back the data, the photographs and the export · usually inside a week. You judge it against what your own team would have produced on the same day.
