DIRANA uses dielectric frequency response (DFR) analysis in order to determine the condition of high-voltage insulation systems such as those in power transformers, bushings, cables and generators.
With DIRANA you can test assets filled with mineral oil, natural and synthetic ester as well as air or vacuum. Commonly tested assets are:
- Power transformers
- Instrument transformers
- Bushings
Additionally, dielectric measurements are available for condition diagnosis of other assets, such as:
- Rotating machines
- Resin-bonded paper (RBP), resin-impregnated paper (RIP) and resin-impregnated synthetic (RIS) bushings
- Cables
Features
Compact and rugged all-in-one test set Revolutionary new FDS & PDC+ algorithm for up to 20x faster testing: Less than 2 hours for a full 10 µHz 1 kHz frequency sweep Fully automatic parameter setting and improved moisture assessment for optimal results Support of ester-filled assets due to new databases for synthetic and natural ester Guided workflow for test setup, execution and assessment for easy analysis without expert knowledge
