Product Description
Electronic Power Comprehensive Analyzer Transformer Load No-Load and No Load Tester
The MYRS-II Transformer Power Tester is a multifunctional measuring instrument that combines the capabilities of both a Transformer Capacity Tester and Transformer Characteristic Parameter Tester. This advanced device accurately measures power frequency parameters including capacity, type, no-load current, no-load loss, short-circuit (load) loss, and impedance voltage for various transformers.
This instrument features compact design, lightweight construction, high measurement accuracy, excellent stability, and simple operation. It completely replaces traditional multi-meter methods for measuring transformer loss and capacity, offering simplified wiring and convenient testing and recording capabilities that significantly improve work efficiency.
Key Features
