Gas & moisture trends
Internal transformer conditions reflected in dissolved gases and moisture.
Industry / Power & Utilities
Power assets are connected. Monitoring should be too.
From generation and renewables to substations, distribution networks, cable routes and energy storage, HERTZINNO combines acoustic and multi-sensor technologies to reveal early fault signals across critical electrical infrastructure.
Industry hub for utility operators, EPC teams, asset owners and maintenance engineers.
A multi-signal view
See the weak signals before they become operating events.
Power-system faults rarely begin as one obvious alarm. They can first appear as dissolved gas trends in transformer oil, ultrasonic emissions from partial discharge, temperature rise along cable routes, traveling-wave fault transients or abnormal sound from auxiliary equipment. The monitoring method should match the physical signal and the asset environment.
This page organizes HERTZINNO capabilities by utility asset area. Detailed technical content remains on the relevant solution and product pages.
Ultrasonic discharge
Corona, tracking and arcing emissions from high-voltage assets.
Temperature rise
Local hot spots and distributed thermal changes along cables and routes.
Grid & machine events
Fault transients and abnormal acoustic patterns from lines and equipment.
01 / Generation
Power Generation & Renewables
Monitor the equipment behind reliable generation.
Conventional and renewable generation sites depend on transformers, rotating auxiliaries, electrical rooms, plant utility systems and long cable routes. Inspection and online monitoring should be selected around each asset and failure mechanism.
Typical monitoring priorities- Auxiliary and step-up transformer condition
- Pumps, fans, motors and compressors
- Compressed-air and process-gas leaks
- Cable, tunnel and fire-risk temperature
02 / Substations
Substations & Transformers
Combine internal transformer health with external fault localization.
Transformer and substation reliability requires visibility into different physical signals. Online DGA follows gases and moisture inside transformer oil, while acoustic and thermal inspection helps locate partial discharge, hot spots and abnormal equipment behavior around the yard and electrical rooms.
Typical monitoring priorities- Transformer dissolved gases and moisture
- Switchgear, GIS and bushing partial discharge
- Acoustic and thermal field inspection
- Continuous abnormal-sound monitoring
03 / Distribution
Distribution & Cable Routes
Improve visibility from overhead feeders to underground cable corridors.
Distribution networks need faster fault sectioning, while switchgear and cable infrastructure need condition information between scheduled inspections. Fault indicators, traveling-wave monitoring, acoustic imaging and DTS address different parts of this operating chain.
Typical monitoring priorities- Overhead line fault indication and localization
- Distribution-line transient monitoring
- Switchgear and cable-terminal PD inspection
- Cable tunnel and route temperature
04 / Energy Storage
BESS & Critical Electrical Loads
Add physical sensing around the systems that support stored energy.
Battery management data is essential, but station reliability also depends on step-up transformers, PCS and switchgear areas, cable trays, cooling systems and auxiliary equipment. Acoustic, thermal and distributed temperature sensing can add visibility around those supporting assets.
Typical monitoring priorities- Step-up transformer internal condition
- PCS and switchgear acoustic or thermal anomalies
- Battery, cable and trench temperature routes
- Pumps, fans, HVAC and cooling equipment
Asset-to-signal map
Match each risk to the sensing method that can see it.
A utility-wide monitoring program does not require one device everywhere. It requires a clear link between the asset, the early physical signal and the inspection or online monitoring layer used to capture it.

Portable inspection, fixed online monitoring and route-level sensing serve different purposes. HERTZINNO can combine these layers according to the asset type, site environment, communication requirements and existing monitoring platform.
Acoustic imaging
Locate partial discharge, leaks and abnormal acoustic sources during field inspection or online monitoring.
Online DGA
Track transformer gases and moisture for earlier internal fault assessment.
DTS & DAS
Use optical fiber for distributed temperature and route-level event sensing.
Grid fault monitoring

Plan the next monitoring layer
Tell us the asset, voltage environment and fault signal you need to monitor.
Share the asset type, operating environment, current inspection method and whether the requirement is portable, fixed or route-level. HERTZINNO can help structure the appropriate combination of acoustic, DGA, fiber and grid-monitoring technologies.
