Cost-optimized early warning system for online DGA monitoring of power transformers

Early, reliable detection of gas and moisture trends in oil
Detect errors, minimize risks
is a critical value for moisture in the oil.
MSENSE® DGA 2/3 is the practice-oriented and retrofit-capable early warning system.
No maintenance and service costs. Monitoring of early indicators, configurable alarms, and integration into SCADA systems.

Monitoring of the primary indicators and detection of Trends

  • The analysis of dissolved and free gases (DGA) is the only online diagnostic option for detecting and analyzing errors in electrical equipment filled with insulating oil. 
  • Fault gases such as hydrogen and carbon monoxide indicate errors in the windings.
  • Moisture indicates oil quality.
  • The MSENSE® DGA 2/3 early warning system can reliably detect gas and moisture trends in oil.
Oil measurement

The early warning and notification system in detail

  • For paper-insulated transformers
  • Detects individual gas concentrations
    • Moisture in the oil
    • Hydrogen (H2)
    • Carbon monoxide (CO)
  • Continuously monitors the primary early indicators for possible damage with thermal and electrical causes
  • Shows negative trends that could develop during the service life of a transformer
  • Warns and notifies the user when an individually defined limit value is exceeded

Before it gets critical. MSENSE® DGA 2/3

Safe and reliable use and top performance, even under extreme conditions such as in the Arctic, desert, or rainforest.
