Performance Features

1) The interface adopts an intelligent color screen display, making operation simple and convenient. The circuit adopts a new generation of fully digital solutions, ensuring long-term instrument stability.

2) Fast testing speed: three-phase transformation ratio testing can be completed with a single connection in just 10 seconds.

3) Blind testing function: transformation ratio and group testing can be performed even when the high and low voltage connection methods are unknown.

4) Suitable for testing the transformation ratio, group, and polarity of transformers ranging from distribution transformers to 1000KV transformers, single-phase transformers, current transformers (CTs), voltage transformers (PTs), and Z-type connected transformers.

5) Wide testing range: up to 10,000 taps, with up to 197 tap positions.

6) AC/DC dual-use: adaptable to lithium battery power supply or 220V AC charger power supply. 7) Features a non-disconnect clock and date display; data storage is available via internal storage and USB flash drive. Internal storage can hold 500 test data entries, which can be transferred to a USB flash drive in Word format, allowing for direct editing and printing on a computer.

8) The instrument has high and low voltage reverse connection protection, as well as transformer short circuit and inter-turn short circuit protection.

9) Small size and lightweight, making it easy to carry and use.
