MSENSE® BM
Online Monitoring for High-Voltage Bushings
According to CIGRÉ, defective bushings are responsible for 17% of all transformer failures and about 50% of all transformer fires. Online monitoring by MSENSE® BM & ETOS® protects against transformer failures without unnecessary false alarms. Continuously, the system monitors the condition of the bushings. Using the patented MR-2/3 reference algorithm in combination with the reference voltage method, the system triggers a warning or an alarm based on the changes in capacitance and additionally the dissipation factor (tan δ) when the limit value is exceeded.

Why is it important to continuously monitor bushings?
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.

A continuous overview of condition and dissipation factors
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.
