How much does a DGA test for transformers cost?

Dissolved gas analysis (DGA) of transformer oil is a technique that measures the types and concentrations of gases dissolved in transformer insulating oil. The cost depends on your method. Sending a sample to a lab costs between $100 and $500 per test. Buying a portable analyzer is a one-time cost of $15,000 to $50,000. An online monitor can cost $25,000 to over $100,000 to install.
