MSENSE® VAM

How can I detect mechanical irregularities on the tap-changer from the outside before they become a serious problem?

One of a kind:
Continuous measurement and detailed analysis from MR

Use vibro-acoustics to analyze the heartbeat of your tap-changer

Prevention is the top priority

100%

additional protection for the tap-changer.

MSENSE® VAM detects anomalies before they become a problem.

Operational reliability and maintenance optimization through the world's first online solution for vibro-acoustic monitoring. Self-learning algorithms.

Enabled

Online detection of mechanical anomalies
Early intervention and prevention of malfunctions and serious incidents

Supplements

Previous monitoring processes for tap-changers, such as analysis of the torque
Detects irregularities before they become problems

Preventive analysis detects possible weaknesses early on

Mechanical irregularities in the tap-changer, e.g. on the spring mechanism and during the switching sequence
Time differences in the switching process compared to reference measurements
Contact anomalies in the tap-changer
Bent selector arms

Detectable anomalies: e.g. loose connection or aged spring mechanism

How MSENSE® VAM works

MSENSE^® VAM intelligently listens into the tap-changer, measures continuously and transmits the measured data online.

Based on algorithms, MSENSE^® VAM can evaluate whether a problem exists and gives recommendations for action. Foreign noises are faded out.

Your benefits:
Increased operational reliability and cost optimization

The first online solution for vibro-acoustic monitoring
Indicates faults early on that would not otherwise be detected
The detailed analysis from MR provides you with possible causes and clear recommendations to prevent malfunctions.
The self-learning algorithm guarantees easy integration into any transformer and can be used for a wide range of tap-changers from other manufacturers.
Can be flexibly combined with other ETOS^® modules to create an integrated, smart system solution
