Advanced Cable Fault Locator & TDR Cable Tester – Complete Underground Power Cable Fault Detection System for Open Circuit, Short Circuit, High Resistance, Flashover, Fault Distance and Cable Pinpointing
Product Description
The Advanced Cable Fault Locator & TDR Cable Tester is positioned as a complete professional solution for modern underground cable maintenance.
The system combines advanced signal acquisition, digital waveform processing and multiple cable fault testing technologies to help engineers identify and locate different types of cable faults.
For customers looking for more than a basic TDR tester, the system can be configured with additional cable route tracing, high-voltage fault activation and pinpointing functions.
Core Testing Functions
Cable Fault Pre-Location
Determine the approximate distance between the test point and the suspected fault.
TDR Testing
Suitable for many open-circuit, short-circuit and low-resistance fault conditions.
High-Resistance Fault Testing
Advanced methods can be used for difficult high-resistance faults.
Flashover Fault Testing
Useful for applicable intermittent or flashover-type faults.
Cable Route Tracing
Identify underground cable direction and route.
Fault Pinpointing
Further narrow the physical fault location after pre-location.
Complete Workflow
Step 1 — Cable Identification
Confirm the target cable.
Step 2 — Cable Route Detection
Determine cable direction and depth where required.
Step 3 — Fault Pre-Location
Use TDR or an appropriate advanced method to calculate fault distance.

FAQ
Q1: What is the difference between a cable fault tester and cable fault locator?
A cable fault tester generally focuses on detecting or analyzing cable faults, while a cable fault locator emphasizes determining where the fault is located. Many modern systems combine both functions.
Q2: What cable faults can the system detect?
Depending on configuration, the system can address open circuits, short circuits, low-resistance faults, high-resistance faults, leakage faults and flashover faults.
Q3: Can it test underground power cables?
Yes. Underground and buried cable fault location is one of the primary applications of professional cable fault location systems.
Q4: Can it locate the exact fault point?
TDR generally provides fault pre-location, meaning it estimates the distance to the fault. For final pinpointing, a route tracer and/or acoustic-magnetic pinpointing system may be used.
Q5: Is the system suitable for field maintenance?
Yes. Portable cable fault location systems are specifically designed for on-site troubleshooting and maintenance.
Q6: How should customers select the correct model?
The correct configuration depends on several factors:
- Cable voltage level
- Cable length
- Cable construction
- Cable insulation type
- Expected fault resistance
- Required testing methods
- Required fault-location range
- Whether cable route tracing is required
- Whether final pinpointing is required
