A generator failure during an emergency is the worst possible time for a generator to fail. Data centers, hospitals, water treatment plants, and utility backup systems all depend on generators that sit idle for months and then must start and carry full load within seconds. Whether they do depends largely on the condition of their insulation — and… Read More »
Motors fail. The question is whether you catch it during a scheduled outage or at 2 AM on a Sunday. Insulation testing is the tool that decides which one. This guide covers everything you need to run a complete motor insulation testing program — from a single 5 kW pump motor to a 2,000 kW medium-voltage drive. It’s… Read More »
Cable insulation fails silently. Unlike a motor that vibrates or a transformer that overheats, a cable with degrading insulation gives you no warning until it faults. And when it does fault, it takes out the circuit — sometimes causing arc flash, fire, or hours of downtime while you trace the problem. Regular insulation testing on cables catches degradation… Read More »
Transformer insulation is the single most critical component determining the life and reliability of a power transformer. Over 60% of transformer failures are linked to insulation breakdown. Once it fails, you’re looking at months of downtime and repair costs that can reach hundreds of thousands of dollars. The good news: insulation problems don’t happen overnight. They develop over… Read More »
