Metrel MI 3280 Digital Transformer Analyser
The MI 3280 Digital Transformer Analyser is a multi-function, portable battery-powered (Li-ion) test instrument. It is designed for diagnosing the turn ratio, phase deviation, and excitation current of both single and three-phase transformers, as well as measuring winding resistance.
Measuring Functions
The MI 3280 offers a comprehensive suite of diagnostic tools for transformer maintenance:
Turn Ratio Measurement: Available for both single-phase and three-phase transformers.
Phase Deviation: Measures the deviation between high-voltage and low-voltage windings.
Excitation Current: Monitored simultaneously during turn ratio testing.
Winding Resistance: High-accuracy resistance measurement for single and three-phase windings.
Key Features
User Interface: A 3.4" colour LCD touchscreen offers easy-to-read results and intuitive navigation.
Simple Operation: Straightforward design allows users to operate the instrument with minimal training.
Data Management: Store results directly on the instrument or transfer them to a PC via USB or the built-in Bluetooth interface.
Software Integration: Includes Metrel ES Manager for creating test structures, editing autotests, and professional report generation.
On-Site Support: Built-in help screens and Autotest sequences streamline the testing process.
Rugged Design: High degree of environmental protection (IP 65 with case closed, IP 54 with case open).
Power: Built-in charger and rechargeable Li-ion batteries included as standard.
