PD-4 Professional Partial Discharge Measuring System

Product catalog summary
Overview: The document provides detailed specifications for the Professional Partial Discharge Measuring System, Type PD-4, designed for diagnosing high voltage insulation issues. It complies with the IEC 60270 standard and features both analogue and digital displays.
Specifications:
  • Detector: Supplied with a calibration certificate, it offers PD ranges of 10 - 100 - 1000, with an input impedance of 50 Ohms. The PD readout is available in LCD graphics, digital, analogue, or phase-resolved patterns, with an uncertainty of ±3% of the range.
  • Filters: The system includes selectable broadband filters with high pass options of 20 kHz or 100 kHz and low pass options of 200 kHz or 400 kHz. The narrow band filter has a middle frequency selectable between 60 and 250 kHz, with a bandwidth of 9 kHz.
  • Gating and Calibration: Features up to 6 individually adjustable hardware gating windows, auto calibration ranging from 10 pC to 10,000 pC, and auto-ranging for PD and voltage measurement.
  • Voltage Measurement: Capable of measuring voltages from 100 V to 1 MV, with a frequency range of 45 to 150 Hz and a voltage scale factor of 1 to 10,000. The uncertainty is 1% of the reading.
  • Display and Interface: Offers analogue and digital displays, with PD activities shown as y(t) plots. It includes an RS232 interface for data transfer and remote control.
  • Physical Characteristics: Dimensions are 455 x 130 x 350 mm, weighing approximately 6 kg. It operates on 230/115 V power supply, with other voltages available on request.
Coupling Device: The PD and AC signals are mixed in a single 50 Ohm coax cable. The PD-channel has an input impedance of 200 Ohms (or 500 for cable measurements), and the AC-channel has an input impedance of 1 MOhm. The bandwidths are 20 kHz to 2 MHz for PD and 45 Hz to 450 Hz for AC.
Battery Calibrator: Supplied with a calibration certificate, it offers charge values of 5, 10, 100, and 1000 pC, with an output capacitance of less than 150 pF and a rise time of less than 60 ns. It is powered by a 9 V battery with a life of over 20 hours.
Measuring Cable: A coaxial 50 Ohm cable, 20 meters long, with BNC-BNC connectors is used for measurements.
