HZ-DGA-900

No.HZ0502001
The Hertzinno HZ-DGA-900 is an advanced online Dissolved Gas Analysis (DGA) system designed for continuous monitoring of power transformer health. By utilizing a combined approach of photoacoustic spectroscopy (PAS) and photonic spectroscopy, it delivers highly sensitive and accurate analysis of fault gases.
The system features an independent innovation in PAS technology, utilizing a MEMS infrared light source and a dual-chamber design to overcome common limitations of traditional PAS systems, such as light source attenuation and mechanical noise from choppers. This robust hardware architecture ensures long-term measurement stability and a maintenance-free operation without the need for carrier or calibration gas consumables.

Comprehensive Gas Analysis: Monitors 9 specific gases (H₂, CO, CO₂, CH₄, C₂H₂, C₂H₄, C₂H₆, O₂, N₂) and moisture (H₂O) .

Exceptional Sensitivity: The two-stage absorption chamber design enables detection of trace gases down to 0.2 ppm.

Rapid Diagnostics: Completes a full measurement cycle within 1 hour.

Innovative Hardware: Employs a double-sided design to separate the gas measuring structure from electronic components for enhanced site reliability.

Maintenance-Free Reliability: Self-calibration capabilities and a standard 5-year warranty ensure low total cost of ownership.

Environmental Resilience: Operates reliably in extreme temperatures ranging from -40°C to 70°C.
