DIRANA can determine the condition of high-voltage insulation systems like in power transformers, bushings, cables and generators with dielectric response analysis.
DIRANA determines the moisture content of the paper and the oil conductivity in oil-paper insulations in a non-invasive way. The measurement results are shown in categories defined by IEC 60422.
DIRANA combines Frequency Domain Spectroscopy (FDS) and an advanced version of Polarization Depolarization Current (PDC+) measurement. In combination with the automated frequency range setting DIRANA ensures the shortest measurement time on all assets at any temperature.
Key features
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
Compact all-in-one test set
Applications
Water analysis of oil-paper insulated assets, such as power transformers, instrument transformers and associated components like bushings
Dielectric measurements, including capacitance, power factor/dissipation factor and insulation resistance, of power transformers, instrument transformers, rotating machines, bushings (RBP, RIP and RIS insulation) and cables
