The proper functionality of a transformer turns ratio test set is of utter importance. When working with electricity and high voltages, precise equipment is necessary to ensure correct operation and safe handling. In order to assure the accuracy of a turns ratio test set, calibration should be performed on a frequent basis.
Calibrating a turns ratio test set can reap many benefits. Test sets that have been calibrated regularly are known to obtain the following:
Calibration of a turns ratio test set minimizes any ratio measurement uncertainties. When calibration is performed, uncertainties within the ratio measurement are processed to determine an acceptable margin of error.
Turns ratio test sets that are calibrated frequently are guaranteed to be more reliable than those that are not. This is because measurements of a test set have been calibrated to be the most accurate.
Any instrument that has been calibrated is said to have a longer life-span than those that have not. This is because instruments that are calibrated are well-maintained and properly used.
A turns ratio test set should be calibrated regular to ensure it is accurate and reliable. Many test sets will have a manufacturer recommendation on how frequent the instrument should be calibrated. Although following this schedule could be beneficial, it is important to note that turns ratio test sets should also be calibrated after the following:
Notably, making a personal calibration schedule for a turns ratio test set is highly recommended. Every test set is used differently; for example, some more frequently than others. For this reason, a test set should be scheduled to be calibrated annually, quarterly or monthly depending on its usage.
Can you calibrate your test set or should you leave it to a lab?
