How to Detect Oil Contamination in Transformers: 6 Critical Methods Explained
After a catastrophic transformer failure that cost my client $1.2 million, I learned that early detection of oil contamination isn’t just important – it’s crucial for survival. Transformer oil contamination can be detected through six primary methods: visual inspection, dielectric strength testing, dissolved gas analysis (DGA), particle count testing, moisture content analysis, and acidity testing.

How Silica Gel Color Changes Protect Oil-Immersed Transformers?
Throughout my 20 years in transformer maintenance, I’ve learned that a simple color change can be the difference between a functioning transformer and a million-dollar disaster. Silica gel in transformer breathers serves as a critical early warning system by changing color from blue to pink as moisture levels increase. This visual indicator helps prevent catastrophic […]
