The A52 Trolley-Mounted System (Advanced) adds 40 kV conditioning, bridge measurement, and multi-pulse up to 2,048 J for the toughest cable faults — factory direct at $34,300.
What Is the A52 Advanced Trolley System?
The A52 extends the trolley platform with 40 kV HV conditioning, an integrated bridge option, and multi-pulse generator up to 2,048 J. Its 0–200 km TDR handles long feeders and high-diversity fault networks. The Linux-based data system stores waveforms for export and analysis.
Why Choose the A52 Over the Standard A50?
The A50 ($29,900) covers routine faults; the A52 ($34,300) adds the capability for high-resistance and intermittent faults on HV feeders. Its 40 kV supply conditions faults beyond the A50's 32 kV, and the bridge module measures extreme-resistance paths. For networks with frequent stubborn faults, the $4,400 premium pays for itself in reduced downtime.
What Are the System's Key Specifications?
The A52 covers 380V–500kV with a 0–200 km TDR (±0.5 m) and 40 kV conditioning supply. Its multi-pulse generator delivers up to 2,048 J with programmable sequences. The integrated bridge module adds precise fault measurement for long feeders.
Who Needs the A52's Advanced Capability?
Reliability-critical utilities and service companies facing high-diversity faults benefit most. The A52 handles water-tree-damaged cables, intermittent flashovers, and long-distance feeders that defeat standard systems. Its data-export feature supports maintenance records and repeat-fault analysis.
