Synergy that works for our customers

DV Power and MR, Maschinenfabrik Reinhausen from Regensburg in Germany have joined forces and cooperate in further development of RMO-TD instruments for the need of OLTC testing using the DRM methodology.

With TAPSCAN DRM, Maschinenfabrik Reinhausen is offering a new service for assesing on load tap-changers using dynamic resistance measurement. MR has chosen DV power intruments for this purpose. TAP SCAN DRM can obtain a quick impression of the switching sequence of the on-load tap-changer in just 30 minutes. Read more about this collaboration in MRs own broschure.

TJH2b Services is an independent analytical laboratory and consulting firm that specializes in diagnostic testing of oil, gas and other insulating materials used in transformers, power circuit breakers and load tap-changers.

We have joined forces to provide a new Dual tap changer analysis. This way, condition assessment of OLTC is brought to the new level - two assessments: operational through a DC test, and laboratory material oil analysis provide reliable indication of the tap changer repair requirements.
