HUMIDITY LEVEL MEASUREMENT
PAPER FROM PROCESSORS
DIRANA can determine the condition of high voltage insulation systems, including power transformers, bushings, cables and alternators. It also determines the moisture content in oil-paper insulators from the dielectric response. The measurement results obtained are compared with values from an integrated database, and the moisture content is evaluated between “dry” and “very wet” values in accordance with IEC 60422.
DIRANA reduces the time required for measurement by 50% by using a combination of time and frequency methods (PDC – Polarization Domain Current – and FDS – Frequency Domain Spectroscopy).
