Detect grid faults before they become outages.
HERTZINNO provides acoustic, DGA, DTS and AI voiceprint monitoring solutions for transformers, substations, switchgear rooms, GIS equipment, transmission assets and underground power cables. Detect partial discharge, overheating, insulation degradation and abnormal equipment sound signatures before they escalate into costly failures.
Power & Grid Asset Reliability Monitoring
HERTZINNO power and grid safety solutions combine online DGA, acoustic imaging, thermal imaging, AI voiceprint analysis and distributed temperature sensing to monitor transformer faults, partial discharge, overheating, cable thermal hotspots and abnormal sound signatures across power infrastructure.
What can go wrong in power and grid assets?
Power failures often begin with weak signals: dissolved fault gases in transformer oil, ultrasonic emissions from partial discharge, temperature rise in cable routes or abnormal sound patterns from mechanical and electrical equipment.
Transformer Internal Faults
Overheating, arcing and insulation deterioration generate fault gases before protection systems respond.
Partial Discharge
Corona, tracking and arcing in high-voltage equipment can lead to insulation failure and unplanned outages.
Cable Thermal Hotspots
Underground power cables and cable tunnels require continuous thermal visibility to prevent overload and fire risks.
Abnormal Equipment Sound
Motors, fans, GIS equipment and auxiliary systems may show acoustic changes before visible degradation appears.
From periodic inspection to continuous grid intelligence.
HERTZINNO builds a multi-layer monitoring architecture for power infrastructure. Online DGA monitors transformer internal health, acoustic imaging locates partial discharge, DTS tracks cable temperature along the full route, and AI voiceprint devices identify abnormal sound signatures from critical equipment.

Power & Grid Safety FAQ
How does HERTZINNO detect partial discharge?
HERTZINNO acoustic cameras capture ultrasonic emissions from partial discharge and convert them into visual sound maps, helping engineers locate corona, tracking and arcing sources.
Why is online DGA important for transformers?
Transformer faults generate dissolved gases under thermal or electrical stress. Online DGA tracks these gases continuously, helping operators identify internal faults earlier than scheduled oil sampling.
Where should DTS be used in power systems?
DTS is suitable for underground power cables, cable tunnels, substations and fire-risk routes where operators need distributed temperature visibility instead of isolated temperature points.
Can the solution integrate with existing monitoring platforms?
Yes. HERTZINNO devices can be connected to SCADA, asset management systems or third-party monitoring platforms depending on the deployment architecture and communication requirements.
