One monitoring layer for transformer health and grid fault response
HERTZINNO combines online DGA, acoustic voiceprint monitoring, overhead line fault indication, smart distribution line monitoring and distributed fiber sensing to cover transformer internal faults, abnormal equipment sound, overhead line events, cable thermal risks and grid corridor disturbances.
From transformer signals to grid-level intelligence.
Different faults produce different physical signals. Transformer internal faults may appear as dissolved gases and moisture. Mechanical degradation may first appear as abnormal sound. Overhead line faults require fast indication and location. Cable routes and grid corridors need distributed temperature and vibration visibility.
Online DGA Layer
Monitors dissolved fault gases and moisture in transformer oil to identify overheating, arcing, partial discharge and insulation deterioration at an early stage.
Voiceprint Monitoring Layer
Learns the normal sound pattern of transformers, cooling fans, oil pumps and auxiliary equipment, then detects abnormal humming, vibration and mechanical sound changes.
OLF Fault Indication Layer
HZ-OLF-100 supports short-circuit fault detection, ground fault detection, poor contact fault detection, insulator fault detection and section-level line fault awareness.
TWF Fault Localization Layer
HZ-TWF-30 monitors medium-voltage overhead distribution lines with traveling-wave fault localization, grounding fault detection, lightning event recognition and cloud-based diagnostics.
DTS & DAS Route Monitoring Layer
Distributed fiber optic sensing monitors cable temperature, tunnel hotspots, route vibration, third-party disturbance and grid corridor security across long-distance infrastructure.
