• Center frequency is adjustable from 10 kHz – 10 MHz in 10 kHz steps

Partial Discharge Measuring

• The model PD3U comprises a Spectrum Analyzer, a PD detector, and a RIV meter in one instrument. This combination enables PD measurements even with a large background noise, such as in non-shielded test areas. Observing the frequency spectrum of a significantly noisy PD signal allows the user to select frequency bands with less disturbance resulting in a clearer pattern acquisition.
• In RIV mode, the instrument has bandwidth of 9 kHz and 270 kHz. When utilizing either the CAL3B or CAL3D calibrator, the range is 400 kHz – 1900 kHz in steps of 100 kHz. Technically, the 4 Channel unit in RIV mode, is a selective µV-meter according to the CISPR weighing curve whereas the repetition rate has a strong impact on the reading.
• Measurements are according to IEC 60270-2000, IEEEC57.12.90, and RIV measurements are according to NEMA/CISPR regulations and other relevant standards.
