Nettet12. jun. 2008 · In this paper a detailed implementation of Duval triangle method was presented for researchers and utilities interested in visualizing their own DGA results using a software program. The Java language is used for this software because of its growing importance in modern application development. Nettet20. des. 2015 · Prediction of fault severity by Duval triangle method limits the concept of EWDGA to EWMEA (Energy Weighted Methane Ethylene and Acetylene). EWMEA requires subset comprising of three of primary fault gases MEA (methane, ethylene and acetylene) to be energy weighed.
