INFOTECH’s On-line Oil and Gas Monitoring Device Takes Center Stage at the Exhibition

As a leading enterprise in the field of on-line transformer oil and gas monitoring, Hubei Infotech System Technology Co., Ltd. made a splendid appearance at the exhibition with its independently developed laser photoacoustic spectroscopy on-line transformer oil and gas monitoring device. The device captured extensive attention from the audience and became the undisputed focus of the exhibition.

The Infotech booth was swarmed with visitors throughout the exhibition, with numerous attendees drawn to the new-generation laser photoacoustic spectroscopy oil and gas monitoring device. Operation and maintenance technicians from power enterprises, as well as industry experts and scholars, showed profound interest in the device. They stopped at the booth to listen carefully to the explanations by Infotech’s staff, and gain an in-depth understanding of the device’s performance features and practical application cases. Experts and scholars also conducted on-site exchanges with Infotech’s team on relevant technical issues. Many professional visitors commented that photoacoustic spectroscopy technology has only recently been applied in the field of Dissolved Gas Analysis (DGA) for oil-immersed power equipment. Infotech’s innovative technologies and excellent application effects have provided an effective new-generation technical approach to solving practical problems in the operation and maintenance of power equipment, and they look forward to the device playing a pivotal role in the intelligent operation and inspection of power equipment.

Independent and Controllable Technologies Lead Industrial Upgrading

Infotech’s independently controllable photoacoustic spectroscopy on-line oil and gas monitoring device has brought a brand-new solution to Dissolved Gas Analysis (DGA) in transformer oil. Adopting high-sensitivity photoacoustic spectroscopy trace gas intelligent sensing technology, the device enables 24/7 uninterrupted monitoring of fault gases such as H₂, CO, CH₄, C₂H₂, C₂H₄ and C₂H₆ in transformer oil under the complex operating environment of power systems. It features high precision, real-time monitoring, low maintenance, stable long-term operation and automatic early warning for anomalies. Relying on its outstanding performance and application cost advantages, the device has successfully broken through industry bottlenecks.

Localized Technologies Boast Extensive Application Scenarios

Infotech’s fully localized on-line oil and gas monitoring device has been widely applied in the domestic and international power markets, bringing direct safety benefits to power industry customers. In the domestic power market, the device has been deployed at UHV substations/converter stations of many national landmark projects including the Zhundong-Wannan ±1100 kV UHV DC Transmission Project, with an installation rate of 60% at all in-operation UHV converter stations across China. In the international power market, the device has been mass-applied in projects such as the Pakistan Mera DC Project. In the actual operation of domestic and international projects, the device has repeatedly played a crucial role and become a standard safety monitoring device for UHV transformers. To date, there have been no equipment safety accidents in all projects where the device is applied.

As a leading enterprise in the industry, Infotech persists in the innovative exploration of high-precision and intelligent oil and gas monitoring technologies. On the one hand, it digs deep into the demands of power industry customers, deeply integrates cutting-edge technologies such as artificial intelligence (AI) and edge computing, accelerates the optimization and iteration of product performance and functions, and provides customers with more intelligent and personalized solutions, empowering the intelligent operation and inspection of global power grids through technologies. On the other hand, it actively leverages its advanced technological and application cost advantages at home and abroad to promote the application of independent core technologies in more industrial production scenarios, enabling its advanced technical devices to be applied in various industrial fields including rail transit, petroleum and petrochemicals, gas power generation, safety monitoring and medical testing.

For a long time, Infotech has achieved remarkable technological breakthroughs in its independent R&D field, and its products have demonstrated excellent performance and stability in practical applications. Amid technological development and transformation, Infotech will continue to lead the development of on-line dissolved gas monitoring technology in oil, and provide tailor-made integrated solutions for application scenarios with different requirements across various industries.
