ndb’s model AE-250E is the newest tool for locating PS within large power transformers. IT uses combined technology of HFCT probe to prove PD exists and then uses 4 acoustic sensors which are moved around various positions ( usually only 4 positions), to take ‘shot views’ using Time of Flight measurements. The unique Mirador software then assembles and analyses the view to give an insightful, 3D view of the transformer and the PD location. If the PD is coming from deep in the core or windings, it will be difficult to late by any test set or technology. Fortunately many PD problems are in connections, joints and splices, which the AE-250E can identify. [Click Ndb AE -250E for brochure]
