Transformer service programmes

Trafoser is bought as a programme with a defined outcome, not as a list of service line items. That is how utilities, industrial operators, IPPs and development-finance programmes actually procure, and it is how these pages are organised.

Fleet condition assessment

A structured survey of your transformer population that produces a ranked, evidence-based picture of asset health and a prioritised intervention plan.

Rehabilitation and life extension

Refurbishing a degraded transformer and returning it to reliable service instead of replacing it — weeks instead of years, at a fraction of replacement cost.

Oil management programmes

Ongoing custody of transformer oil condition across a site or fleet. A single oil test is data; a trend is a decision.

Training and capacity building

Capability that stays behind after demobilisation. Frequently a contractual requirement where a development bank funds the work.

01Remote and cross-border sites

Reach is part of the scope

For a remote or cross-border site, the programme also carries shipping, temporary import, customs, permits, abnormal-load transport, site generation, fuel and water planning, satellite communications, and a contingency for the part that does not clear customs. It is planned before the technical work, because it decides whether the technical work happens.

02From a finding to a programme

Programme scope builder

Choose what testing or inspection has shown, and see the tests that characterise it, the standards it is read against and the programmes that address it.

Select a finding to see the tests, standards and programmes that follow from it.

Guidance, not a diagnosis. What a result means depends on the unit's history, loading and other readings, and only an engineer who has seen all of them can say.

Transformatör sayısı

Fleet size sets the order of work.

Sent with the enquiry

Recorded for the engineer. The scope does not change.

Liquid-filled asset

Dry type: Cast resin and VPI — inspection, cleaning and electrical testing. No oil work applies. Transformer scope

Gerilim aralığı

Where this leads

Start with a condition assessment

Tell us the assets, the site and the situation. If the fleet's condition is unknown, an assessment is the lowest-commitment way to find out what you actually have — and it defines whatever comes next.
