Product Introduction

The broadband impedance spectrum (BIS) was developed to address the drawbacks of the conventional time domain reflectometry (TDR) method when locating faint localized defects in cables.

This rechargeable portable instrument serves as a non-destructive testing system. Combined with our self-developed BIS testing software and hardware, the system boasts high identification sensitivity and positioning accuracy for cable local defects and intermediate joints, with a positioning error less than 0.5%.

Adopting the frequency-domain measurement principle, the incident signal is reflected at impedance discontinuities. The reflected waves are analyzed at the transmitting end, and the positions of cable impedance discontinuities are calculated based on the signal propagation speed within the cable.

FAQ: Cable Impedance Spectrum Analyzer

Q1: What core principle does this cable impedance spectrum analyzer adopt?

A1: It works on the frequency-domain measurement principle. The linearly swept sine incident signal reflects at cable impedance discontinuities. The system analyzes reflected waves or standing waves, then calculates the exact position of cable defects based on signal propagation speed inside cables.

Q2: What advantages does BIS technology have over the traditional TDR method?

A2: Conventional TDR fails to identify tiny, subtle localized cable defects. Our BIS system delivers much higher sensitivity, with positioning error less than 0.5%, and accurately locates millimeter-level hidden cable faults that TDR cannot detect.

Q3: What types of cable defects can this instrument detect?

A3: It can detect defects caused by dampness, overheating, external mechanical damage, chemical corrosion, radiation, water trees, aging and other factors, as well as abnormal intermediate cable joints.

Q4: What is the effective detection range of the device?

A4: The effective testing length covers cables from 50 meters up to 100 kilometers, applicable for most medium and high-voltage power cables.

Q5: Is this tester a non-destructive testing device? Will it damage the tested cables?

A5: Yes, it belongs to a complete non-destructive testing system. No high voltage is applied to cables during testing, so no damage will be caused to cable insulation and internal structures.

Q6: How long does a single cable test take?

A6: One full test is finished within 1 minute, greatly improving the working efficiency of cable maintenance teams.

Q7: Can it test cables without original cable ledger and length records?

A7: Absolutely. It can automatically measure cable total length and locate fault points without relying on original drawing or account information.

Q8: What is the battery life and charging condition?

A8: Equipped with an 8000mAh rechargeable battery, continuous working time exceeds 6 hours, and fast charging is supported for outdoor field operations.

Q9: What are the applicable working temperature and humidity ranges?

A9: Operating temperature: -15℃ ~ +50℃; Working relative humidity ≤80%, suitable for harsh outdoor construction environments.

Q10: Does the system support automatic test report generation?

A10: Yes. It can annotate defects on time-domain, frequency-domain and compensated spectra, classify faults by type and severity, and export standardized electronic test reports automatically.
