  • Page 15: Product Description

    4 Product description 4 Product description The detection of dissolved gases in transformer oil is generally considered to be the first indication of emerging faults in transformers. Several interna- tional standards highlight the relevance of this examination method, includ- ing the IEEE Std C57.104™-2008, IEC 60422, IEC 60567 and IEC 60599 standards.

  • Page 16: Scope Of Delivery

    4 Product description The device is available in two device versions: Measured variables Hydrogen (H2) Carbon Moisture Oil tempera- monoxide (H2O) ture (CO) MSENSE® DGA 2 MSENSE® DGA 3 MSENSE® DGA 2 for measuring and analyzing the fault gas hydrogen (H2) present in the transformer oil, for detecting the oil moisture content and for measuring the oil temperature.

  • Page 17: Function Description

    4 Product description 4.2 Function description The MSENSE® DGA 2/3 measuring head is positioned in the transformer in- sulating oil. There is often a large distance between the measuring head and the origin of the gases. It is therefore important for the early detection of gases that the oil at the installation position is in motion, either due to natural convection or due to artificially generated oil circulation.
