Multi-Function Transformer Power Tester, Portable High Accuracy for Load & No-Load Test

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
  • Accurate measurement of various distribution transformer capacity
  • Comprehensive testing of no-load current, no-load loss, short circuit voltage, short circuit loss, and capacity
  • Automatic range switching with wide voltage and current measurement ranges
  • Three different meter testing methods
  • Automatic wiring verification and three-phase voltage/current vector diagram display
  • Full current load testing for transformers up to 1000kVA
  • Automatic correction for waveform, temperature, non-rated voltage, and non-rated current
  • High-brightness 320×240 LCD screen with brightness adjustment and touch button operation
  • User-programmable storage for 40 test sample parameters
  • Built-in real-time clock for automatic test date recording
  • Integrated thermal printer for fast result printing
  • Data storage for up to 500 test results with PC connectivity
  • Extended range measurement capability using external voltage and current transformers
