- SOKEN Digital Partial Discharge Analyzer DAC-PD-9A
Effective diagnostics to maintain the performance and operation of critical facilities
SOKEN Model DAC-PD-9A is a digital partial discharge analyzer that applies to IEC 60270, which is referenced in a variety of IEC standards for PD measurement.
DAC-PD-9A provides narrow band, wide band and ultra-wide band measurement up to 40MHz, which enables to select an appropriate frequency band for each specimen.
All data will be sampled in time series, and statistical measurement can be performed. In the wide band measurement, the positive and negative polarities of the discharge waveform are discriminated and displayed. The further analysis is possible by creating graphs with the stored data.
Digital Partial Discharge Analyzer
