NRYZ-2008 Transformer Load Tap Changer Tester

NRYZ-2008 Transformer Load Tap Changer Tester is an integrated measuring instrument for measuring and analyzing the electrical performance indicators of on-load tap-changers of power transformers and special transformers. It adopts microcomputer control, through the design of precision measurement circuit, it can realize accurate measurement of the on-load tap-changer's transition time, transition waveform, transition resistance, three identical phases and other parameters.
The instrument has the functions of displaying, analyzing, storing and printing the measured data. It can diagnose the potential fault of the load tap switch in the preventive test of the power equipment and the maintenance of the transformer.
