GENESYSAMS & LES

DEVELOPED BY In development

Know your assets. Plan with confidence.

GENESYS AMS & LES keeps one record per asset, scores its condition from tests, inspections, online monitoring and robot findings, and estimates its remaining life with the confidence band shown. Maintenance follows the condition, not the calendar.

The problem

A transformer can serve for decades. How much life is really left in it?

The evidence usually exists. It is just spread across systems, reports and notebooks, so maintenance follows the calendar because nothing better is at hand.

Records in many places
Nameplates in one system, oil tests in a lab report, inspection notes on paper. Nobody sees the whole asset at once.
Maintenance by the calendar
Fixed intervals send crews to healthy assets and can miss the ones that are ageing faster than planned.
One number nobody trusts
A single remaining-life figure hides how uncertain it is, so it is either trusted too much or ignored.

How it works

Every score names what it was built from.

Each part of a transformer ages in its own way, and each has its own evidence. AMS & LES reads four kinds of it and stores each against the asset it describes, so a planner can open a health index and see the test, the inspection or the reading that moved it.

A transformer opened up: the bushings on top, the windings and oil inside the tank, and the tap changer on the side.

Fleet view

Which assets need attention first, and why.

Across every site, the assets that need attention move to the front. The fleet board shows where they are; the register and the plan show what happens next.

A fleet board: rows of transformers standing on pads coloured by health, green, amber and red, with the red ones at the front.

Reading the band

How to read an estimate, and what to do next.

Each estimate names its model and its inputs: for a transformer, typically a thermal ageing model driven by load and ambient temperature, the trend of dissolved gases from oil tests, and inspection findings.

A wide band: collect data first
The record is thin: few tests, a short history or readings that disagree. An extra oil test or an online monitor is usually worth more than an early replacement.
A narrow band near the limit: plan it
When the band crosses the replace limit inside the planning horizon, the asset belongs in the capital plan, with the evidence attached.
Every change has a cause
When a new test arrives the estimate moves, and the record shows which input moved it, so a planner can tell a measurement from a model change.

Life estimation does not replace engineering judgement. It summarises the record so it can be compared across a fleet. Read the note: remaining life, with the error bars shown.

GENESYS AMS & LES, in brief

A transformer can serve for decades. But how much life is really left in it? GENESYS AMS and LES reads everything you know about each asset: the tests, the inspections, the repairs and the live readings.

It turns them into a clear picture of health, and an honest estimate of the years ahead, with the uncertainty shown, not hidden. Across the whole fleet, you see which assets need attention first, and why.

So budgets go where they matter, and work is planned by condition, not by the calendar. GENESYS AMS and LES. Know your assets. Plan with confidence.
