MEBC-F Transformer Ratio Group Tester Send email to us

1. The instrument incorporates a three-phase precision inverter power supply internally, eliminating harmonic interference from mains voltage during measurements for enhanced accuracy. When powered by a generator, no impact is observed.
2. Utilizes three-phase output voltage to accelerate testing speed. Capable of measuring phase angle, automatically identifying connection groups 0-11. For low-voltage rectifier transformers with multiple windings, the low-voltage side requires no disconnection to measure turns ratio and 7.5° angle deviation.
3. Suitable for a wide range of transformers, particularly ideal for measuring Z-type transformers, rectifier transformers, grounding transformers, electric furnace transformers, phase-shifting transformers, and similar types.
4. Features high/low voltage reverse connection protection, transformer interturn short-circuit protection, tap changer position failure protection, and full output short-circuit protection, enhancing instrument stability.
5. After inputting rated parameters, it automatically measures transformer turns ratio, error value, and tap position. It accurately identifies the exact position of tap switches, even for asymmetrical taps, supporting up to 99 tap positions.
6. Features a 7-inch high-brightness touchscreen color LCD with clear visibility under strong light. Fully touchscreen operation with free switching between Chinese and English interfaces.
7. The instrument supports both printer output and USB flash drive interfaces, and can be equipped with an RS232 interface for paperless operation.
8. Features a multi-functional engineering plastic case designed for cold/heat resistance, waterproof sealing, and shock/drop protection, ideal for field testing.
9. Compatible with Android phones or tablets: follow the WeChat official account, download the dedicated app, and use the specialized software to fully control the instrument, store and upload test data for convenient review.
