Sampling Guide
Obtaining a sample of your transformer's dielectric fluid is an important step in understanding and managing the health and reliability of these valuable assets. However, you cannot simply "crack the valve" and fill any container.

Obtaining a representative sample begins with understanding a few key points:
Safety - What PPE is required to safely sample this transformer?
Equipment - What tools will I need to sample this transformer?
Procedures - What are the proper steps to obtaining the sample?
Containers - What are the industry approved containers?
Storage & Shipping - How do I safely store, pack and ship the samples to my laboratory and ensure a representative sample arrives intact?
Taking care to follow industry standards, such as ASTM D923-15 Standard Practices for Sampling Electrical Insulating Liquids, and guidelines set by industry leaders can help to ensure you answer the questions listed above. SDMyers are experts in the transformer industry and over the past half-century have developed guidelines and training courses to ensure asset safety & reliability through proper sampling techniques.
