Suitable for precise measurement of a series of power frequency parameters such as material, capacity, type, no-load current, no-load loss, load loss, impedance voltage, DC resistance, etc. of transformers.

This instrument is a multifunctional measuring instrument, consisting of an active transformer capacity tester, transformer characteristic parameter tester, transformer DC resistance tester, and transformer material analyzer.

Includes transformer capacity. Transformer no-load loss. The transformer has functions such as load loss and code level determination. It is compact in size, easy to operate, and convenient to use.

It can accurately measure a series of power frequency parameters such as material, capacity, form, no-load current, no-load loss, load loss, impedance voltage, DC resistance, etc. of various transformers.
