The instrument can display, analyze, store and print the measured data, it solves the problem that the current on-load tap-changers of power transformers are backward in the measurement methods, without the dedicated measurement means. It can timely diagnose the potential faults of the on-load tap-changer in the power equipment preventive test and transformer overhaul, having great significance to improving the reliability of the power system operation.
