Transformer maintenance training for your technicians
Une compétence qui demeure après la démobilisation. Souvent une exigence contractuelle lorsqu'une banque de développement finance les travaux.
Who transformer maintenance training is for
Your technicians learn transformer maintenance, oil handling, testing and the reading of results, to the same published methods the programmes use, and, where a programme is under way, on the job beside the team doing the work. The aim is capability that stays after demobilisation.
Development-finance and donor-funded programmes
Development banks and donors frequently make capacity building a contractual requirement, so that the utility can keep the work going after the contractor has left. Training delivered with the programme is a direct way to meet it.
Utilities and operators keeping the work in-house
Asset and maintenance teams who will look after the transformers once the programme team has demobilised, and want their own technicians sampling, testing and maintaining to the same methods.
Rural electrification and mini-grid programmes
Distribution transformer fleets spread over long distances, where local technicians see each unit far more often than any visiting team can.
What the training covers
Topics are chosen with you from this list, for the work your technicians will carry on.
Transformer maintenance
Routine inspection and maintenance of the transformer and its fittings, from breathers, gaskets and seals to cooling and the protection devices, and how to record what is found.
Oil sampling and handling
Taking oil samples to IEC 60475, and samples for dissolved gas analysis to IEC 60567, without contaminating them; handling oil on site with spill containment, and keeping used oil under a chain of custody.
Test equipment operation
Running the routine field tests safely and consistently, and recording each result with the method it was measured to, so that one set of results can be compared with the next.
Reading results: condition and dissolved gases
Condition-assessment method and what the results mean: oil results read against IEC 60422, and dissolved gas analysis interpreted to IEC 60599, or to IEEE C57.104 where the specification is written to IEEE.
Safe working around high-voltage plant
Safe working practice around energised and de-energised high-voltage plant: permit-to-work, isolation, lock-out tag-out (LOTO) and switching discipline.
On-the-job mentoring
Where a programme is running, your technicians work beside the team through the real work, from sampling and testing to treatment and the reading of results, so the capability stays after demobilisation.
How the training runs
Phases, in order. The dates are agreed with you; where the training runs alongside a programme, they follow that programme's mobilisation plan.
Topics agreed
The subjects chosen with you from the scope, around the transformers your technicians look after and the work they will carry on.
Training in the agreed topics
Your technicians taken through the topics agreed, to the published methods the programme team works to.
Mentoring during the work
Where a programme is under way, your technicians join the team on it for sampling, testing, treatment and the reading of results.
Handover
Course materials left with your team, so the methods stay after the programme team has gone.
What you provide
Who is to be trained
Your technicians, the transformers they look after and the work they will carry on, so that the topics are chosen around it.
Time for your technicians
When your technicians can step away from their duties, so that the dates are set around the work they already carry.
What your team keeps
Technicians who can carry the work on
Your own staff, able to sample, test, maintain and read results to the methods the programme used, after demobilisation.
Results that fit the trend
Samples and tests taken to the same published methods as the programme's, so your team's results can be read alongside ours in each unit's trend.
Course materials
The written material from the training, kept by your team for reference and for technicians who join later.
Standards the training works to
The training works to the same published methods as the programmes, so what your technicians learn is what the programme team does on site. The oil tests and diagnostics themselves are listed on the capabilities page.
| Standard | What it governs here |
|---|---|
| IEC 60475 | Sampling oil for the general tests |
| IEC 60567 | Sampling oil for dissolved gas analysis |
| IEC 60599 | Interpreting dissolved gas results |
| IEEE C57.104 | Interpreting dissolved gas results where the specification is written to IEEE |
| IEC 60422 | Reading oil results against the limits for oil in service |
| IEEE C57.152 | Guide to the electrical field tests on a transformer |

Transformer maintenance training: common questions
What can transformer maintenance training cover?
Transformer maintenance and oil handling; the operation of test equipment and the interpretation of its results; condition-assessment method and the interpretation of dissolved gas analysis to IEC 60599; and safe working practice around energised and de-energised high-voltage plant. The topics are chosen with you, course materials are provided, and the training can run as on-the-job mentoring while a programme is under way.
Does the training cover oil sampling and dissolved gas analysis?
Yes. Technicians learn to take oil samples to IEC 60475, and samples for dissolved gas analysis to IEC 60567, without contaminating them, and to read the results: dissolved gases interpreted to IEC 60599, or to IEEE C57.104 where the specification is written to IEEE, and the other oil results against IEC 60422. The point is to know what a result should lead to, whether a repeat sample, a shorter interval or a closer look at the unit.
Can training run alongside another programme?
Yes. On-the-job mentoring during a condition assessment, a refurbishment or an oil-management programme puts your technicians beside the team through the real work: sampling, testing, treatment and the reading of results. The aim is capability that stays after demobilisation, which is the purpose of the training.
Why is training often part of development-finance projects?
Development banks frequently make capacity building a contractual requirement, so that the utility can sustain the work after the contractor has left. Training delivered alongside a programme, on the utility's own transformers and with the test methods its technicians will go on using, is a direct way to meet that requirement.
