Portable Cable Fault Locator & Cable Fault Tester for Underground Power Cables – TDR Cable Fault Detection, Distance Measurement, Open Circuit, Short Circuit & High Resistance Fault Location
Product Description
The Portable Cable Fault Locator and Cable Fault Tester is a professional cable diagnostic solution designed for fast and accurate fault detection and fault distance measurement in underground and buried power cable networks.
Using advanced Time Domain Reflectometry (TDR) and modern digital signal processing technology, the system analyzes reflected signals generated by cable impedance changes and helps engineers determine the approximate location of cable faults.
The equipment can be used for different types of cable faults, including low-resistance faults, short circuits, open circuits, high-resistance leakage faults and high-resistance flashover faults, depending on the selected testing method and system configuration.
Its portable design makes it suitable for utility maintenance teams, electrical contractors, cable installation companies, industrial plants and field service engineers.
Main Testing Functions
TDR technology is widely used for identifying impedance changes and determining the distance to a fault.
Typical Applications
Customer Pain Points Solved
Problem 1: Cable fault location takes too long
Instead of manually checking a large underground cable route, the tester provides an estimated fault distance, helping engineers narrow down the inspection area.
Problem 2: Underground cables are difficult to access
The portable system can be taken directly to the field, reducing dependence on laboratory testing.
Problem 3: Different fault types require different testing methods
The system can support multiple fault detection methods depending on cable type and fault characteristics.
Problem 4: Excavation costs are high
Accurate fault pre-location can help reduce unnecessary excavation and shorten repair time.
FAQ
Q1: What types of cable faults can this tester detect?
It can be configured to detect low-resistance faults, short circuits, open circuits, high-resistance faults, leakage faults and flashover faults.
Q2: Can it be used for underground cables?
Yes. It is designed for cable fault diagnosis in underground and buried cable networks.
Q3: How does TDR locate a cable fault?
The instrument sends a test pulse into the cable and analyzes the reflected signal caused by an impedance discontinuity to calculate the fault distance.
Q4: Is the equipment portable?
Yes. The portable design is intended for on-site cable maintenance and troubleshooting.
