Multi-Pulse Current Fault Tester — A10 (Advanced)

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.

Key Features

• Ten measured waveforms displayed simultaneously for selection and analysis
• Ten LV short-circuit pulse waveforms from one discharge; auto-select optimal
• Real-time display of distance change between test point and fault point
• Cable path direction detection; WiFi + SIM remote data transmission

Technical Specifications

Applicable Scenarios

• Medium-voltage distribution networks — pre-locate faults on 10–35 kV feeders
• Long rural feeders — reach faults beyond basic TDR range
• Dense urban underground cable systems — pinpoint in congested networks
• Emergency restoration after storms — rapid multi-pulse fault location
• GIS and cross-bonded systems — test complex cable configurations
• High-resistance and intermittent faults — locate faults single shots miss

Testing Method

1. Safety check & isolation — de-energize and ground both ends
2. Connect test leads — attach TDR/impulse leads to the faulted phase
3. Low-voltage pulse pre-location — obtain a first distance reading
4. Multi-pulse discharge — apply ≤40 kV sequences for stable flashover
5. Review 10 waveforms — select the optimal one (or auto-select)
6. Track real-time distance — monitor convergence during discharge
7. Confirm direction — verify cable route orientation
8. Record & transmit — save to 32 GB; share via WiFi/SIM if needed
9. Pinpoint on site — mark the dig point (±0.2 m)
10. Discharge & secure — auto-discharge, verify zero voltage

Quality & Delivery

• 100% factory tested — calibration and test certificate included
• CE certified — EU compliance
• Export packaging — foam-lined transit case
• Lead time — 15–20 days
• After-sales — 1-year warranty, lifetime maintenance, free training

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.
