UHV-3000 On Load Tap Changer Characteristic Tester-Catalog

Product catalog summary

Product Introduction
The UHV-3000 Transformer On-Load Tap-Changer Tester is designed to measure various parameters of the on-load tap changer, which is the only moving part connected to the transformer circuit. It is crucial for detecting the action sequence, switching time, transition waveform, transition time, transient resistance, and three-phase synchronism of the transformer on-load tap changer.

Product Features

Lightweight instrument with output current.
Two current outputs for a wider test range and higher stability.
Automatic calculation of transition resistance and transition time values.
Strong reliability due to a perfect protection circuit.
5.7-inch large LCD display for easy on-site operation.
USB flash disk storage function for storing more data waveforms.
Independent operation of the keyboard and one-key flying shuttle for quicker and more convenient use.
