Turbine oil varnish: why it forms while antioxidants remain
Varnish forms when degradation products from hot spots, micro-dieseling or static discharge exceed oil solvency, even with antioxidants left. Here is how.

Moisture in transformer paper and oil: how temperature moves it
Warming pushes water from transformer paper into oil and cooling pulls it back slowly, so an oil moisture result shows paper moisture only at equilibrium.
판단 프레임워크
기술적 판단의 기준을 개별 사례에 적용할 수 있도록 정리합니다.
