Product Description

The XHJF801B is a multifunctional partial discharge (PD) tester built for insulation diagnostics in factory and laboratory environments. Combining contact ultrasonic (AE), ultra-high-frequency (UHF), high-frequency (HF) and transient earth voltage (TEV) detection with PRPD/PRPS phase-resolved analysis, it gives transformer and switchgear manufacturers, third-party testing laboratories and research institutes a precise tool for factory acceptance testing, type tests and long-term insulation condition evaluation.

Target Audience

Designed for manufacturers, laboratories & test institutes:

Transformer, switchgear and GIS manufacturers performing factory acceptance & type testing
Third-party testing laboratories and research institutes for insulation diagnostics
Power equipment quality inspection teams evaluating insulation aging and defects

Key Features

Four detection channels: AE ultrasonic, UHF, HF and TEV for comprehensive insulation analysis
PRPD and PRPS phase-resolved analysis for precise discharge source identification
Contact ultrasonic covers SF6 (20~80kHz) and oil-filled (80~200kHz) equipment
High resolution of 0.1dB across all sensors for repeatable measurement data
Data storage, viewing, deletion and waveform recording for test reports
Multi-level alarm thresholds with color-coded amplitude display
Large-capacity lithium battery and compact 1.35kg mainframe for flexible test setup
Linux embedded OS supporting future function expansion and integration

Applications

Factory acceptance testing (FAT) of transformers, switchgear and GIS
Insulation defect location and type tests in the laboratory
SF6 gas-insulated and oil-filled power equipment diagnostics
Long-term insulation aging evaluation for research institutes

FAQ

Can the XHJF801B be used for factory acceptance testing of transformers?
Yes. Its contact ultrasonic (AE) channel covers 80~200kHz for oil-filled equipment, and the HF channel (0.3~30MHz) measures discharge on grounding leads, making it suitable for transformer FAT and insulation diagnostics.
Does it support PRPD/PRPS analysis for diagnostic reports?
Yes. The instrument provides phase-linear, PRPD and PRPS analysis windows, enabling clear discharge source identification and supporting professional insulation diagnostic reports.
What is the measurement resolution and accuracy?
All detection channels offer a resolution of 0.1dB (0.1dBm for UHF) with a linearity error below ±20%, ensuring repeatable, high-precision measurement data.
Which frequency bands does it cover for different equipment types?
AE: 20~80kHz (SF6) and 80~200kHz (oil-filled); UHF: 300MHz~1500MHz; HF: 0.3MHz~30MHz; TEV: 3MHz~100MHz, covering GIS, transformers, switchgear and cables.
Can data be exported for third-party test reports?
Yes. Test data and waveform recordings can be saved and exported to a USB drive (FAT32), allowing easy integration into factory test reports and third-party certification documentation.
