Product Description

General Information 

Transformer on-load switch tester is a test equipment for testing the on-load tap changer of action sequence and switching time. Transformer On-load Tap Changer Tester is mainly applied to measure the  transient waveform,  transient time, transient resistance value, three-phase synchronization of transformer on-load tap-changers.

 

Feature

  • Test transformers of type Y0, Y, and △, and display resistance values directly.
  • Automatically analyze waveform faults and mark the faults.
  • Automatically adjust resistance values and time ranges based on sampling data.
  • Display synchronization status of three phases for transformer type △.
  • Test with or without winding.
  • Support four-terminal connection mode for high-accuracy resistance measurement.
  • Enable continuous testing to save power-off time.
  • Generate word reports.
  • Equipped with an 800×480 colorized LCD with touch screen and a high-speed printer.
  • Store up to 1000 groups of data and allow saving to USB flash disk.
