Urban grids increasingly rely on underground cables, where faults are harder to locate and
outages have significant social impact.
Key Features & Benefits:
Traveling Wave Sensor: Bandwidth 1kHz–20MHz; discharge
measurement range 1mA–3A.
Data Collection: Hidden discharge currents, fault traveling waves,
and power frequency fault currents.
Precision Timing: ±20ns synchronization for accurate fault
positioning.
Extended Monitoring: Optional modules for circulation,
temperature, and vibration.
Power Supply: Energy harvesting, solar, induction (30–1000A), or
mains (AC220V/DC24V).
Durability: Double-layer anti-interference design, IP66 protection,
resistant to extreme temperatures and EMI.
Impact: Enables rapid detection of insulation defects and discharge
faults, improving repair speed and enhancing urban grid reliability and
resilience.
