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.
