How to Test for Resistance—2026 Pro Tips: The Complete Industrial Guide
Read moreWhen a 200 MVA power transformer trips offline unexpectedly, the root cause is rarely a sudden lightning strike. More often, it’s a slow, invisible degradation that could have been caught months earlier—with a simple resistance test. In 2026, as electrical grids across South America, Southeast Asia, the Middle East, and South Africa expand rapidly, knowing […]

What Is Transformer Testing and Why Is It Important?
Read moreWhat Is Transformer Testing? Transformer testing involves a series of diagnostic and acceptance tests performed during manufacturing, commissioning, routine maintenance, and troubleshooting. These tests verify the transformer’s condition, identify potential faults, and help prevent unexpected failures. Common transformer tests include: Turns Ratio Test (TTR): Verifies the winding turns ratio and detects shorted turns or incorrect […]
