- 7-inch touch screen with wiring diagrams for each step
- Harmonic analysis and vector display for wiring checks
- English user interface; English operating system available
Overview
Some transformers are sold as copper-wound when their windings are actually aluminium, and some users under-declare transformer capacity. This analyzer is designed for these problems: it identifies the winding material of a transformer from the different electrical characteristics of copper and aluminium, and measures its real capacity.
It combines three instruments in one: a transformer capacity tester, a transformer characteristic (loss) tester and a winding material analyzer. A built-in battery and three-phase 50 Hz source mean capacity and load loss can be measured with no external supply; one charge covers more than 100 transformers. A DC resistance function with six current levels up to 10 A is included.

Frequently asked questions
How does it tell copper from aluminium?
Copper and aluminium windings have different electrical characteristics. The analyzer measures these and identifies the winding material without opening the transformer.
Does it need an external power supply?
Not for capacity and material tests: the built-in battery and three-phase source supply the test signal. For no-load and load loss tests, an external supply and regulator are used.
Who uses it?
Utilities checking customer transformers, and buyers who want to verify transformers on delivery.
