Study Notes

Key Indicators of Transformer Health

Hydrogen, carbon monoxide, and moisture in insulating oil are primary early indicators of possible thermal and electrical damage in transformers, according to IEC standards (IEC 60475, IEC 60567, ASTM D 4057).
Analysis of dissolved gases (DGA) can quickly and cost-effectively identify five out of six common transformer problems, as noted by CIGRE's 2011 "Guide for Transformer Maintenance."

MSENSE® DGA Technology

MSENSE® DGA devices, when combined with ETOS®, classify errors based on concentrations of gases such as carbon dioxide, acetylene, ethylene, methane, ethane, and oxygen.
The MSET/MSET DGA software allows customization of threshold values, trend tracking, daily measurement counts, and communication parameters.
MSET DGA enhances monitoring and error classification using MSENSE® DGA 5 and MSENSE® DGA 9 devices; both solutions are included in the product package.

Data Management and Visualization

MSET/MSET DGA presents measured data in a clear format, with graphical representations of trends that can be exported for further analysis.

Advanced Fault Analysis and Classification

MSENSE® DGA 5 offers intensive monitoring of fault gases, essential for critical and strategically important transformers.
The MSENSE® DGA 9 device utilizes Rogers or Duval algorithms to provide detailed classification of thermal and electrical faults.
