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

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
