- PARTIAL DISCHARGE MEASUREMENT -
Effective diagnostics to maintain the performance and operation of critical facilities
Partial discharge is electrical discharge that can lead to serious problems in high-voltage insulation system.
The partial discharge waveform that occurs when voltage is applied contains important information related to insulation defects.
By identifying the locations where the partial discharge occurs and making a comprehensive analysis based on data such as the amount of charge and discharge pattern, it is possible to assess the risk of the system.
Partial discharge analysis is effective to prevent the system from being in dangerous situations.
SOKEN Model DAC-PD-9 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-9 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.
Software
PD Analyisis
The polarity of partial discharge waveform is automatically
determined and the number of positive and negative occurrences
are displayed.You can create 2D and 3D graphs from saved
data and use it for discharge analysis.

V-Q Mode
When V-Q mode is selected, max PD charge amount (Qmax/pps) according to rise/fall of the test voltage is automatically acquired to see the voltage/charge amount characteristic.
