Mineral oil-filled electrical equipment - Application of dissolved gas analysis (DGA) to factory tests on electrical equipment (IEC 61181:2007 + A1:2012); German version EN 61181:2007 + A1:2012

Title (German)

Mineralölgefüllte elektrische Betriebsmittel - Anwendung der Gasanalyse für gelöste Gase (DGA) auf Werksprüfungen von elektrischen Betriebsmitteln (IEC 61181:2007 + A1:2012); Deutsche Fassung EN 61181:2007 + A1:2012

Overview

This International Standard specifies oil-sampling procedures, analysis requirements and procedures, and recommends sensitivity, repeatability and accuracy criteria for the application of dissolved gas analysis (DGA) to factory testing of new power transformers, reactors and instrument transformers filled with mineral insulating oil when DGA testing has been specified. The most effective and useful application of DGA techniques to factory testing is during the performance of long-term tests, typically temperature-rise (heat run) and overloading tests on power transformers and reactors, also impulse tests on instrument transformers. DGA may also be valuable for over-excitation tests run over an extended period of time. Experience with DGA results, before and after short-time dielectric tests, indicates that DGA is normally less sensitive than electrical and acoustic methods for detecting partial discharges. However, DGA will indicate when these partial discharges become harmful to the insulation and the partial discharges may then be detected by inspection. The responsible committee is K 182 "Flüssigkeiten und Gase für elektrotechnische Anwendung" ("Fluids and gases for electrotechnical application") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
