Shanghai Hertzinno Technology Co., Ltd. products

The Hertzinno DGA900 is an advanced online Dissolved Gas Analysis (DGA) system designed for the real-time monitoring of transformer conditions. Leveraging MEMS technology, the DGA900 surpasses traditional PAS technology by providing maintenance-free operation while monitoring nine types of gases and moisture in transformer insulation oil. It uses MEMS IR light sources, which enable precise modulation of different frequency bands, improving gas analysis sensitivity. Its dual-chamber design separates the gas analysis chamber from the acousto-optic chamber to prevent contamination and enhance system longevity. The system features a vacuum degassing and pressure leveling mechanism, maintaining pressure equilibrium with transformers and preventing downtime. With a robust automatic calibration system, Hertzinno ensures high measurement accuracy over time. The DGA900’s photoacoustic spectroscopy eliminates the need for consumables, providing a reliable and cost-effective solution for optimizing transformer performance and preventing outages.

The HZ-OLF-100 Smart Grid-Transmission Line Fault Indication System is designed to enhance the reliability and efficiency of power network operations by accurately identifying fault locations and types. Utilizing advanced passive acquisition technology, it effectively minimizes false alarms using current and voltage amplitude along with phase characteristics. Remarkably, the system requires no additional power supply, operating efficiently through solar energy, power induction, and lithium battery options. A standout feature is its ability to form a self-organizing network, allowing ultra-long-distance data transmission without reliance on 4G/5G networks, thereby reducing construction costs. The system boasts high adaptability to extreme outdoor conditions, functioning optimally in temperatures ranging from -25°C to 70°C. It continues to operate effectively even during prolonged periods of overcast and rainy weather. Further technical features include a combination of Gaussian Filtering and Wavelet signal processing for precise fault analysis and location, supported by synchronous fault phasor analysis.
