Managing your HV/MV transformer's fleet:
reduce the risks of breakdowns and associated costs.
As an industrial or operator, you may need to manage several HV/MV electrical transformers, sometimes up to several hundred, spread across different sites.
Managing the transformer fleet can quickly become complex, especially when each transformer differs in terms of criticality, age, and power.
The Laboratory OKSMAN SERAPHIN assists you in analyzing the risks and criticality of your transformers. It collaborates with you to develop analytical recommendations for the upcoming year (fleet assessment) up to the maintenance plan, which establishes intervention priorities in the short- and medium-term.

Fleet management assistance
If your company operates in one of the following fields and has multiple transformers spread across one or more sites, fleet management assistance will meet your needs.

High-voltage/medium-voltage transformers serving energy stakeholders:
- Electricity production
- Electricity transmission
- Electricity distribution
Some leading companies in energy production and distribution own transformer fleets comprising up to 300 units!

High-voltage/medium-voltage transformers serving the electro-intensive industry:
- Oil and gas
- Metallurgy, cement industry
- Paper, cardboard, wood, rubber, and plastic industry
- Chemical industry
- Manufacturing of electrical equipment
- Automotive industry and transportation equipment
Manufacturing companies are modernizing their energy efficiency by using more efficient high-voltage transformers to reduce losses.

High-voltage/medium-voltage transformers serving the tertiary and information sectors:
Generalist or specialized maintainers who cater to:- Municipalities
- Healthcare and defense infrastructures
- Transportation: airports, ports, train stations, and railways
- Information and communication:
- Programming and broadcasting
- Telecommunications (wired, wireless, and satellite)
- Data centers (data processing and hosting)
Companies are doubling, or even tripling, their high-voltage transformers to ensure continuous power supply.
Get a concise overview of your transformer's status and prioritize your maintenance actions.

Opt for on-site expertise
Identify transformers requiring special attention with laboratory specialists. If necessary, an expert will visit your site to conduct a visual inspection of your equipment, audit previous interventions and review maintenance plans and specific events. They also integrate activity outlooks and investment programs.
Adapt your analyses to the criticality of your equipment and improve your budget.
The heterogeneous situations of each of your transformers (unique non-redundant ones, aging ones, those subject to major faults, etc.) in relation to your operating perspectives make prioritization essential in managing your fleet.
Instead of a systematic and recurring plan, we recommend an efficient analytical plan targeting the specific monitoring needs of each of your priority assets, thus improving your budget.

Get an assessment of your transformer fleet and have a comprehensive overview.
After each analysis, receive a detailed diagnosis of your transformer. At the end of the analytical plan, laboratory specialists provide you with a comprehensive assessment of your fleet, including the initial assessment, analyses conducted, observations, and analytical recommendations for your next campaign.
Increase the reliability of your HV/MV transformers with a strategic maintenance plan.
In addition to recommendations, our expert can collaborate with you to establish a maintenance plan, prioritizing actions based on the severity indices of audited and analyzed transformers.
