Multi-Pulse Current Fault Tester — A10 (Advanced)
Multi-Pulse Current Fault Tester — A10 (Advanced)
Couldn't load pickup availability
The A10 Advanced Multi-Pulse Current Fault Tester locates intermittent and high-resistance cable faults with ±0.2 m pinpoint accuracy, capturing 10 waveforms per discharge — factory direct at $3,800.
What Is the A10 Advanced Multi-Pulse Fault Tester?
The A10 Advanced is a TDR and multi-pulse generator in one instrument, covering low-voltage pulse, HV impulse flash, and multi-pulse methods up to 40 kV. It captures 10 measured waveforms simultaneously per discharge and auto-selects the optimal one. Built-in WiFi and SIM enable remote waveform transmission to support engineers.
Why Does Multi-Pulse Outperform Single-Shot Testing?
Fault flashover is probabilistic — a single discharge has limited chance of triggering breakdown on intermittent faults. The A10 Advanced fires controlled sequences and captures 10 short-circuit pulse waveforms per event, boosting flashover probability toward 97% over a 10-impulse sequence. Real-time distance tracking confirms the reading converges as the fault stabilizes.
What Are the A10 Advanced's Key Specifications?
The A10 Advanced measures distances from 5 m to 100 km with ±0.2 m pinpoint accuracy and a 5 m blind zone. Its 12.1-inch industrial LCD with 32 GB storage displays waveform history. Multi-pulse generator output reaches 40 kV, and standby time exceeds 6 hours on AC220V/DC12V power.
How Does the A10 Advanced Compare to a Standard TDR?
A standard TDR like the A10 locates low-resistance faults but misses intermittent and high-resistance faults. The A10 Advanced adds integrated multi-pulse conditioning and 10-waveform analysis — the same capability as a separate TDR plus impulse generator. At $3,800, it replaces two tools with one unit.

FAQ
What is a multi-pulse current fault tester?
A combined TDR and multi-pulse generator that locates intermittent and high-resistance faults a standard TDR misses.
How accurate is the A10 Advanced?
It achieves ±0.2 m pinpoint accuracy with a 5 m–100 km range and 5 m blind zone.
How does multi-pulse improve fault detection?
Repeated impulses raise flashover probability from ~30% per shot toward 97% over 10 impulses.
Can the A10 Advanced be operated remotely?
Yes — built-in WiFi and SIM transmit waveforms to support engineers for remote analysis.
How does it compare to the standard A10 TDR?
The A10 Advanced ($3,800) adds integrated multi-pulse conditioning, replacing a separate impulse generator.
