Ensuring Long-Term Reliability and Lifespan
The Temperature Rise Test is fundamentally a test of longevity and reliability. Its function extends far beyond initial operation, focusing on the product’s entire service life. This is especially critical for the insulation systems in electromechanical equipment like motors and transformers. A fundamental rule of thumb states that for every 10°C that the operating temperature exceeds its rated limit, the life of the insulation is halved. Therefore, the Temperature Rise Test is not just a pass/fail check for immediate failure; it is a precise measurement to ensure that the product’s thermal performance will allow it to operate reliably for its entire designed lifespan. A successful test result is a promise of durability and a predictor of reduced long-term failure rates.
