“DIRANA is the fastest test system for reliable moisture determination of oil-paper insulated power transformers.”

Benefits of this solution

Moisture determination

Moisture leads to a reduced breakdown strength of the oil and an accelerated aging of the cellulose insulation. The determination of moisture is vital for evaluating the remaining lifespan of your transformer.

Combined advantages

DIRANA combines advanced time domain spectroscopy (PDC+) with frequency domain method spectroscopy (FDS). As well as the moisture content of the transformer, DIRANA also determines oil conductivity, dissipation/power factor and capacitance.

Software support using PTM

DIRANA operates with the Primary Test Manager ™ (PTM) software: The easy to use software determines all relevant parameters, provides automatic analysis and requires no expert knowledge.

Easy and comfortable testing

With DIRANA you get all the required components in just one box, which makes it easy to transport (19 kg/ 42 lbs). Its simple wiring concept and clamps with integrated guard connections make setting up tests easy and fast.
