Description
Hua Mao and co-authors review live monitoring of gases dissolved in transformer oil, in a 2025 paper. A transformer's oil betrays its health: stray sparks, hot spots, and arcs each brew telltale gases. Reading them early warns of failure and grades the gear's aging. The old way, lab tests on drawn oil, is slow, and the gases themselves can burn or blow, a risk to crews on site.
The review sorts the live tools built in the last six years. One line runs a mini gas chromatograph at the tank. Another reads light spectra from the oil. A third sniffs with gas sensors. Each is scored on how little it can detect, how fast it answers, and what it costs to keep. The authors see the field moving toward smart, sharp, always-on watch, feeding a grid that guards itself.
