MSENSE® BM

How can I detect high-voltage bushing errors in good time?

Continuous monitoring of high-voltage bushing with MSENSE® BM

Early detection of high-voltage bushing errors

Evaluating operating reliability

17%

of transformer failures can be traced back to a defect in the bushings.

MSENSE® BM continually and reliably monitors conditions.

Robust and reliable online monitoring. Reliable messages and recommendations for action to superordinate systems.

Why is it important to continuously monitor bushings?

17%* of transformer failures can be traced back to defective bushings.
Continuous monitoring and evaluation of the condition of the bushings is imperative.
MSENSE^® BM makes it possible to detect faults in bushings early on and to take action before the transformer is damaged.

Possible causes of transformer damage

A continuous overview of condition and dissipation factors

The MSENSE^® BM online monitoring system provides reliable, unambiguous condition assessment of high-voltage bushings.
MSENSE^® BM monitors the relevant variables directly at the electrical bushings (RIP, OIP, or RIS) of the voltage levels from 10 kV to 800 kV. Um = 765 kV.
An innovative and field-tested algorithm monitors the condition of the bushing in terms of a change in capacitance (C) and the dissipation factor (tan δ) and compares the change to the limit values.
