Transformer capacity characteristic tester transformer operation maintenance and repair



is a high-precision detection device used for accurately measuring the capacity and multiple electrical characteristics of power transformers, widely applied in the operation, maintenance, and repair of transformers in power, railway, petroleum, and other systems.

In simple terms, it is like a precision instrument that conducts a "full physical examination" for transformers, mainly used to determine the actual performance and energy efficiency level of transformers, and to verify whether the capacity data on their nameplates is authentic.

⚙️ Main Functions and Measurement Parameters

This instrument integrates multiple testing functions, and one device can often replace various traditional meters. It can measure the following key parameters:

Core parameters: actual capacity, no-load current, no-load loss, short-circuit voltage (impedance voltage), and short-circuit loss (load loss) of the transformer.

Advanced parameters: some high-end models also support measuring zero-sequence impedance, harmonic content, waveform distortion, and conducting vector analysis.
