With Ultrasound examination, we detect and identify abnormalities even before they cause functional problems. The specific sound quality is made audible with headphones and the intensity is visualised on the display.
Using a contact probe and magnesium probe, we check the transformers on all sides. The high-voltage switches are measured remotely via air only.
We can detect spark discharge, partial discharge and corona. Corona can occur above 1000V and forms a conductive path between conductors which eventually causes a short circuit.
We detect these faults at an early stage, preventing a lot of damage from short circuits and operation/production downtime.
