VAM ANALYSIS SERVICE

The VAM takes the pulse of the on-load tap-changer – MR provides the diagnosis

The condition of the on-load tap-changer is critical for the operation of your transformers. Using vibro-acoustic measurements (VAM), you get meaningful data at an early stage. VAM records characteristic vibration signals that an on-load tap-changer emits during a tap-change operation. The installed MSENSE® VAM monitoring system, measurements taken on site by the MR TESSA® VAM service or your own devices, such as TESTRANO 600 from OMICRON, provide the data.

Measurement Procedure

Functional Scope

Creating meaningful diagnoses from the measured vibration signals is challenging and requires a detailed understanding of the switching sequences of on-load tap-changers. As the leading global manufacturer of on-load tap-changers, MR and its experts have unique knowledge in order to interpret VAM data thoroughly.
