The A10 Cable Fault Flash Tester locates underground cable faults in minutes with ±0.5 m accuracy across a 0–100 km range — CE certified and factory direct at $2,800.

What Is the A10 Cable Fault Flash Tester?

The A10 is a professional Time Domain Reflectometer (TDR) used by utilities and contractors to measure the distance to cable faults before excavation. It uses low-voltage pulse and pulse-current methods to detect reflections along power cables. The instrument covers 0–100 km and displays results on a 12.1-inch HD color touchscreen.

What Cable Faults Can the A10 Detect?

The A10 detects short circuits, open circuits, and low-resistance ground faults — the most common failure modes on distribution feeders and industrial cable runs. It also identifies cable joints and verifies full cable length during commissioning. High-resistance faults above roughly 500 Ω require HV conditioning before the A10 can measure them.

How Accurate Is the A10 Fault Tester?

The A10 achieves ±0.5 m distance accuracy with a sampling rate of 3.125–400 MHz and adjustable pulse widths from 20 ns to 40 µs. A 2% velocity factor error shifts a reading by 20 m on a 1 km cable, so the A10 allows velocity factor adjustment in 0.01 steps. Two-end testing confirms readings before excavation.

How Does the A10 Compare to the Megger TDR2000?

The A10 costs $2,800, while the equivalent Megger TDR2000 ranges from $4,000 to $6,000 — a 40–58% saving with identical TDR capability. The A10 includes built-in WiFi and SIM remote transmission as standard. It runs a Linux-based operating system for stable field operation.

What Is Included with the A10?

Each A10 ships with a signed factory test certificate, CE compliance documentation, a foam-lined aluminum transit case, and export packaging for sea freight. Standard orders ship within 10–15 days Qingdao/Tianjin/Shenzhen. Every unit includes a 1-year warranty, lifetime maintenance support, and free online training.

Applicable Scenarios

Distribution feeder fault pre-location — locate faults on 10–35 kV distribution feeders before excavation
Street lighting & LV network maintenance — fast fault distance measurement on urban LV cables
Industrial plant cable troubleshooting — verify cable integrity in plant power systems
New cable commissioning — measure cable length and verify installation quality
Cable joint monitoring — identify impedance changes at joints along aging feeders

Testing Method

Safety check — confirm the cable is de-energized and grounded at both ends
Connect — attach test leads to the cable under test
Set parameters — select cable type and adjust velocity factor
Run the test — transmit the pulse and read the fault distance
Mark the distance — record the reading; note joints on the trace
Confirm — repeat from the opposite end and verify consistency
Hand off — pass the distance reading to the pinpointing stage (C11)
