Mainly used to measure the transient waveform, transient time, transient resistance, and three-phase synchronicity of transformer on-load tap-changers.

1. High output current and lightweight.

2. Tests YN, Y, and Δ transformers, displaying resistance values directly without conversion.

3. Can measure with or without windings.

4. Waveform display automatically adjusts resistance and time amplitude based on sampled values.

5. Comprehensive protection circuitry ensures high reliability.

6.7-inch LCD display for easy on-site operation.

7. Automatically stores 500 sets of data.
