Technical Features

It is suitable for a wide range of transformer types, including Z-type transformers, rectifier transformers, grounding transformers, furnace transformers, phase-shift transformers, balanced transformers, Scott transformers, and inverse Scott transformers.

1. Automatically measures transformer ratio, error value, and tap changer position. It can accurately measure the exact position of asymmetrical tap changers, especially for those with asymmetrical taps. It can measure up to 99 tap changer positions.

2. The instrument utilizes a three-phase precision inverter power supply, eliminating the harmonic effects of mains voltage during measurement, resulting in more accurate and faster measurements.

3. A three-phase output voltage increases test speed, allows for phase angle measurement, and automatically identifies transformer wiring groups 0-11.

4. Features include high and low voltage reverse polarity protection, transformer turn-to-turn short-circuit protection, tap changer misalignment protection, and output short-circuit protection, enhancing instrument stability.

5. Features a 7-inch high-definition color touchscreen LCD with a modular display.

6. The instrument can be connected to an external printer for paperless office work.
