KDZD9104 Integrated Partial Discharge Analyzer for High‑Voltage PD Measurement

KDZD9104 Integrated Partial Discharge Analyzer for High‑Voltage PD Measurement

Applications:

This analyzer is widely used in high‑voltage laboratory testing, power equipment factory inspection, on‑site commissioning and condition diagnosis for power utilities. It applies to partial‑discharge measurement of transformers, mutual inductors, high‑voltage cables, bushings and capacitors. It serves teaching labs, research institutes and power‑industry training centers, supporting offline PD inspection, optional fault location and continuous on‑line monitoring tasks. It complies with international and domestic standards for partial discharge measurement for acceptance tests and fault‑feature analysis of various high‑voltage apparatus.

Profile:

KDZD9104 is a desktop four‑channel comprehensive partial discharge analyzer equipped with a TFT touch‑screen display. Designed for insulation‑performance evaluation of high‑voltage power equipment, it integrates signal amplification, multi‑mode filtering, high‑speed data acquisition, data processing, graphic visualization and automatic test‑report generation. This instrument meets the requirements of IEC 60270‑2000, GB/T 7354‑2003 and DL/T 417‑2006. It supports multi‑channel synchronous sampling for electric and optical PD signals. Optional modules enable fault point location and long‑term on‑line continuous monitoring, realizing multi‑functional integration of measurement, diagnosis and recording. Multiple built‑in anti‑interference algorithms handle complex field noise conditions. Operators can store test waveforms, review historical records and export standardized reports for lab research and on‑site power‑equipment inspection work.

Features:

  • Four independent acquisition channels supporting both electrical BNC input and optical signal input for flexible sensor connection.
  • Multiple sampling rate options: 1 M, 5 M, 10 M for different test‑scene requirements.
  • Six‑gear adjustable gain range from ‑40 dB to 60 dB; supports manual gain setting and automatic gain adjustment.
  • Configurable hardware and digital band‑pass filter with adjustable low‑cut and high‑cut frequency to suppress on‑site electromagnetic interference.
  • Rich anti‑interference functions including static interference suppression, dynamic interference filtering, antenna gating and polarity discrimination.
  • Diverse display modes: ellipse, straight‑line and sine‑wave PD patterns; supports Q‑φ, N‑φ, PRPD two‑dimensional and three‑dimensional spectrum analysis.
  • Manual and automatic data storage, waveform playback, screen capture and one‑click automatic test‑report generation.
  • Multiple external interfaces including USB, RJ45 network port, RS232 and VGA for data export and peripheral expansion.
  • Supports internal and external synchronization modes, adapting to power‑supply frequencies from 50 Hz to 500 Hz.
  • Optional functions: partial‑discharge fault location and continuous on‑line monitoring for high‑voltage equipment.
