Recently, the power industry standard DL/T1432.2-2025 "Inspection Specification for Online Monitoring Devices of Substation Equipment Part 2: Online Monitoring Devices for Dissolved Gases in Transformer Oil" issued by the National Energy Administration of China has been officially implemented. Hubei Infotech Systems Technology Co., Ltd., relying on years of experience in the research and development of online monitoring technology for dissolved gases in oil and on-site operation and maintenance, has participated in the revision and preparation of standards, and has made significant breakthroughs in deeply participating in the development of industry technical standardization.

This standard is the second part of the DL/T1432 series of technical specifications and is the latest version that replaces the 2016 version of DL/T1432.2-2016 standard. It is applicable to the inspection of online monitoring devices for dissolved gases in transformer oil. Infotech™️ is deeply involved in the development of new standards, promoting the upgrading of core technologies such as oil sample preparation, minimum detection concentration test requirements, measurement response time test requirements, cross sensitivity test requirements, special functional tests, and optimization measurement error test requirements.

The new standard fully establishes a standardized system for quality supervision throughout the entire life cycle of online monitoring devices for dissolved gases in transformer oil, helping the industry to form a unified and on-site monitoring device inspection specification. The implementation of the new standard will achieve standardization of the entire process of production, sampling, and operation of transformer oil and gas online monitoring devices, and improve the ability of monitoring devices to accurately capture latent faults in transformers. This has significant value in significantly improving the safety and reliability of transformer operation and supporting the implementation of intelligent operation and maintenance of the power grid.

Infotech™️'s ability to participate in standard preparation work is a recognition of the company's online monitoring technology strength and market influence for dissolved gases in transformer oil by the industry. In the future, Infotech will actively implement and apply standards, continuously iterate high-quality monitoring products guided by standards, drive product innovation through standardized research and development, and continue to provide compliant, stable, and accurate safety monitoring solutions for the global power system, helping the safe, intelligent, and efficient operation of new power systems.
