Transformer Design Analysis
WIth the software and hardware tools available today, it is possible to verify the performance of the transformer before building it.
An example is the 3D simulation of stray losses and temperature distribution on a rectifier transformer for aluminium smelter with 80 kA LV current. This simulation allows for the verification of the presence of tank hot spots. These hot spots may deteriorate gaskets of the tank cover or of busbars, causing oil leakage and the transformer would need to be taken out of service. The direct and indirect costs of this type of outage are order of magnitudes bigger than the cost of a study.
However, to perform these advanced simulations, it is necessary to have both skilled resources and the time and tools to dedicate these resources to these tasks.
With our experience and the high end simulation tools which we use (Infolytica) and develop, we can perform very advanced design analysis. See a partial list below. If what you need is not listed, then ask us anyway and we may be able to support you.
