Voluntary Standards Cover the Spectrum: from Power Line Noise Emissions to Precision Irrigation


In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:

Noise Emissions from Overhead Power Lines and Substations
Power lines and substations and are crucial components of bringing electricity into homes and businesses, but they can also bring noise to their surroundings through “corona discharge,” or a limited electrical breakdown of the air. Whether a crackling sound or a low frequency hum, these noises must be measured so that they can be taken into consideration when developments are being built near electrical equipment. IEEE 430-2017, IEEE Standard Procedures for the Measurement of Radio Noise from Overhead Power Lines and Substations, is a new standard developed by ANSI member and accredited standards developer IEEE. It provides uniform procedures for the measurement of radio noise generated by corona discharge from overhead power lines and substations. The procedures in the document apply in the frequency range of 0.010 MHz to 1000 MHz, with an emphasis on the standard amplitude-modulation broadcasting and television broadcasting.

IEEE is the world’s largest technical professional organization for engineering, computing, and technology professionals, with 423,000 members in over 160 countries. The organization fosters collaboration among its members in technologies including computing, sustainable energy systems, aerospace, communications, robotics, healthcare, and more.

Precision Agriculture and Irrigation
Precision agriculture is the use of big data and predictive analytics in agriculture to yield greater results with fewer resources. Farmers may use sensor technologies, GIS data, and other IoT end-devices to conserve resources while utilizing precision agriculture. Within the context of irrigation, farmers can use systems that analyze crop, soil, and weather data to determine if a field needs to be irrigated, saving money by reducing unnecessary water use. ANSI member and accredited standards developer the American Society of Agricultural and Biological Engineers (ASABE) recently released two standards that provide guidelines to support precision irrigation: ANSI/ASABE S632-1 JUL2018, Precision Agriculture Irrigation Language: Core Concepts, Processes, and Objects, which enables an industry-wide format of data storage that can be used by irrigation data analysis and prescription programs; and ANSI/ASABE S632-3 JUN2018, Precision Agriculture Irrigation Language: Irrigation System Operations, which guides management-level communications and record-keeping as they pertain to irrigation operations.

ASABE is dedicated to the advancement of engineering for agricultural, food, and biological systems. The membership organization is open to all stakeholders interested in the technologies for these systems, which support the production of food, fiber, timber, and renewable energy sources through efficient and environmentally sensitive methods.
