Smart Grid & Transformer Monitoring

Online DGA,HERTZINNO,

Online DGA for Transformer

The Hertzinno DGA is a new-generation online DGA featuring proprietary technological innovations.By integrating enhanced photoacoustic spectroscopy (PAS) with photonic spectroscopy, this system enables continuous online monitoring of 9 fault gases and trace moisture in transformer oil.The system provides the earliest possible warning by detecting faults during their formation phase, before electrical protection systems respond.

Transformer Acoustic Fingerprint Monitoring

HERTZINNO acoustic fingerprint systems learn the normal voiceprint of transformers and detect abnormal humming, vibration, cooling fan noise, oil pump degradation and mechanical changes. Combined with online DGA, voiceprint monitoring gives operators a broader view of transformer health.
DTS & DAS Fiber Sensing for Smart Grid Monitoring,HERTZINNO,

Fiber Sensing for Smart Grid Assets

HERTZINNO DTS and DAS systems turn fiber optic cables into distributed sensing networks for smart grid infrastructure. DTS provides continuous temperature visibility along power cables, cable tunnels, trenches and transformer-related routes, while DAS detects vibration, disturbance and third-party interference along transmission corridors, underground cables and critical grid perimeters.

Strength of HERTZINNO DGA

01

MEMS IR

The electronically modulated MEMS infrared light source replaces mechanical choppers, eliminating vibration noise and enhancing detection selectivity and stability.

02

Gas Chambers

The two-stage absorption chamber combining gold-coated tubular absorption cavities with resonance enhancement technology enables precise capture of trace gases.

03

Vacuum Degassing

The system employs vacuum negative pressure degassing to perform temperature-controlled degassing of oil, thereby accommodating measurements of mineral oil and other types of oil.
