The transformer on-load tap-changer tester is used to measure and analyze the electrical performance indicators of power transformers and special transformers on-load tap-changers in power systems.

Product Features

Using computer control, through a specially designed measurement circuit, the transition time, transition waveform, transition resistance, and three identical periods of the on-load tap-off switch can be measured directly by the tap-off according to needs and on-site conditions. The switch leads can also be measured by the transformer three-phase bushing and neutral point direct wiring.
