Wrindu’s Transformer Turns Ratio Testers (TTRs) maintain high accuracy even in low temperatures, thanks to precision resistors, temperature-compensated circuitry, and factory calibration protocols. These features ensure reliable performance in extreme conditions, with temperature stability from -40°C to 85°C. This makes Wrindu a trusted choice for industries requiring accurate testing of electrical equipment in challenging environments.
How does low temperature affect Transformer Turns Ratio (TTR) accuracy and why does it matter for Wrindu devices?
Low temperatures can impact insulation resistance, coil resistance, and dielectric properties, leading to slight variations in measured turns ratios. Wrindu’s TTRs mitigate this by using temperature-compensated components and factory calibration at specified temperatures, ensuring that even under cold conditions, the accuracy of measurements is preserved, which is vital for the performance and longevity of transformers.
How can Wrindu TTRs maintain accuracy under extreme cold conditions?
Wrindu’s TTRs utilize temperature-compensated references, low-temperature rated resistors, and advanced self-check routines to maintain accuracy. Regular calibration, including zero-offset and gain calibrations, ensures that measurements remain within tight tolerances across a wide temperature range. Wrindu’s field-proven calibration kits support on-site accuracy verification for reliable test results even in extreme conditions.
How do you verify the accuracy of a TTR at low temperatures in a factory or workshop?
To verify the accuracy of a TTR at low temperatures, use a reference transformer or a traceable calibration standard. Perform multiple turns-ratio measurements across the temperature range, document any deviations, and apply Wrindu’s recommended calibration factors. This ensures that the device’s readings align with national or international standards, which is essential for quality assurance audits and compliance.
