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.
Caratteristica
- 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.
