Transformers tested, delivered, installed and monitored by our team


Before it leaves our workshop, every transformer undergoes a battery of tests to guarantee its compliance, among other things, with the basic international standard IEC 60076.

test platform

With its 3-strong team the test platform forms a veritable “control tower” in the workshop and is involved in the transformer manufacturing process from the very beginning. Our test technicians start by controlling the quality of the windings ensuring they are compliant with the design sheets provided by the design office, then they are involved at every stage of production through to the final acceptance of the transformers: the Factory Acceptance Tests, often carried out in the presence of the customer.

A happy customer is a loyal customer!

celduc® transfo systematically invites its customers to the factory acceptance tests on their transformer. This provides an opportunity to discuss the project the transformer is for and allows us to explain the test procedures carried out and the results obtained.  As the transformers manufactured in Sorbiers go into use on every continent and every ocean, it is not uncommon for our customers to make a long trip over to see us.

Transformateur sanglé​




This is a mechanical device placed on the transformer tank that records any shocks suffered by transformer on arrival and estimates their severity.


This is an electronic device placed on the tank which records the time and geographical location of the slightest shock event affecting the transformer during transport. It is essential that the device be returned to celduc® transfo so that we can consult the record of the shock events and print out the report.

For transformers that are to be shipped by sea, celduc® transfo can provide SEI4c packing (wooden crate and watertight cover), which meets standard NIMP15, to protect your equipment against the elements.
