Service to the point:

assume responsibility
profit additionally

The regular maintenance and servicing of transformers is both a demanding and responsible task. Nevertheless, there are many possible reasons why this task cannot always be fully accomplished. Take advantage of the qualified service of WGM Support. We offer you demand-oriented services based on the latest testing technology, sound advice and, in addition, an intelligent IT solution that not only supports you in planning maintenance and repair measures more efficiently, but also in controlling them more specifically and documenting them consistently.

Our Services:

Targeted localization of partial discharges


Partial discharges in the insulation system are caused by external influences and lead to damage to the solid insulating material component. Such damage is often accompanied by a further propagation of a fault. In many cases, this material aging causes a partial breakdown in a limited period of time and thus a failure of the equipment. In order to detect critical faults in time before transformers fail and thus require expensive repair or replacement, regular measurement of internal partial discharges is recommended. However, the investment in suitable measurement technology for such tests is high and means a long-term capital commitment.

Furthermore, correctly detecting partial discharge signals on site is usually costly and difficult. Save the effort and the high investments: WGM Support has intelligent measurement technology based on sound sensors and profound know-how for the on-site measurement of partial discharges on transformers. With our portable measuring system, we reliably localize potential sources of error for partial discharges. All measurement results are analyzed by us and visualized in a 3D graphic. You will receive a detailed test report on the basis of which further specific repair measures can be initiated. If you require further information, please contact WGM Support.
