The Portable Standard Test System (380V–35kV) locates faults on live AND de-energized cables with live-safe coupling — factory direct at $15,000.
What Is the Portable Standard Test System?
This complete kit adds live-network fault location capability to the portable package. Its capacitive live-safe coupling lets utilities locate faults on energized feeders without interrupting service first. It includes TDR, HV supply, impulse generator, and acoustic-magnetic pinpointer.
Why Is Live-Network Fault Location Important?
Many faults must be located without a shutdown window — hospitals, data centers, and critical infrastructure cannot tolerate extended outages. The Standard system's live-safe coupling measures on energized feeders while maintaining safety. This reduces outage duration from hours to the minimum required for repair.
What Are the System's Key Specifications?
The system covers 380V–35kV with live-safe capacitive coupling rated for the network voltage. TDR range is 5–100 km (±0.5 m) with 3.125–400 MHz sampling. HV supply outputs 0–32 kV at 1,536 J, and burn-through reaches 60 kV/600 mA. System weight is approximately 95 kg across four cases.
How Does the Standard System Compare to the Basic?
The Basic system handles de-energized cables only; the Standard ($15,000) adds live-network coupling and testing capability. The $3,000 difference buys the ability to respond to faults without scheduling outages — a critical feature for reliability-focused utilities. Both share the same TDR and HV core.
