ASTM D3613 for Sampling Insulating Liquids for Gas Analysis and Water Analysis
ASTM D3613 Standard Practice for Sampling Insulating Liquids for Gas Analysis and Determination of Water Content
3. Significance and Use
3.1 A study of gases and moisture contained in insulating oils from transformers and other electrical power apparatus can frequently give an early indication of abnormal behavior of the apparatus, and may indicate appropriate action be taken on the equipment before it suffers greater damage. Specific gas and moisture content can be determined from oil samples for this purpose. Care must be taken in drawing samples to prevent contamination and to ensure a truly representative sample.
