Zhuhai Huawang Technology Co., Ltd. (HUWOR) participated in drafting Q/GDW 12082-2021, the technical standard for wireless sensors used in the Internet of Things (IoT) for power transmission and transformation equipment, issued by State Grid Corporation of China (SGCC). The company is listed among the drafting organisations of the standard, which was published and implemented on 2021-12-06.
About the standard
Q/GDW 12082-2021, titled Technical standard of wireless sensors for the internet of things for power transmission and transformation equipment, specifies the requirements for the types, naming, identification, technical requirements, testing, inspection rules, marking, packaging, transport and storage of wireless sensors.
The standard applies to wireless sensors used on power transmission and transformation equipment at 35 kV and above; wireless sensors applied to equipment at other voltage levels may refer to it. It defines the product-level specification that covers sensor classification, power supply modes (P1-P4), environmental and electromagnetic compatibility (EMC) tests – the same categories that shape the design of the wireless sensor products HUWOR manufactures.
Why the standard matters to customers
For utilities and integrators deploying wireless sensor networks in substations and on transmission lines, Q/GDW 12082-2021 is the reference that defines what a compliant wireless sensor must satisfy. HUWOR’s participation in drafting the standard means the company’s sensor products were designed with direct knowledge of the specification’s intent, not merely checked against it afterwards:
- Sensor naming and identification follow the standard’s conventions
- Power supply modes and environmental test requirements are built into the product design
- Wireless sensors are designed for interoperability within the State Grid IoT architecture
A standard participation history, now documented
HUWOR’s contribution to the standard is publicly verifiable. The drafting organisation list of Q/GDW 12082-2021 includes Zhuhai Huawang Technology Co., Ltd. alongside the drafting institutes and manufacturers of the State Grid system. As an SGCC enterprise standard, Q/GDW 12082-2021 is not published on the national standard platform; publicly available copies are distributed through third-party standard sites, while the official distribution channels are China Electric Power Press and the State Grid internal standard system. HUWOR hosts an official full-text copy of the standard for reference: Q/GDW 12082-2021 full text (Chinese, PDF). The standard information is documented on several public standard databases: the entry at freebz.net (standard title, number, issuing body, dates, drafting organisations and personnel), the standard forum thread at bbs.biaozhuns.com (standard cover page, full-text PDF and drafting information), and the guifanku.com standard library.
How the standard relates to HUWOR products
The HUWOR wireless sensor family – including the TEV, UHF, ultrasonic and combined partial discharge sensors, temperature and humidity monitors, and leakage current sensors – is developed within the framework of the Electric Power Internet of Things (EPIoT). The company’s role in drafting the wireless sensor technical standard is part of a broader contribution to national and industry standards that spans the sensors, testing instruments and online monitoring systems in its portfolio.
