The Institute of Electrical and Electronics Engineers, Inc. (IEEE) approved a new standard for switching devices in low-voltage circuit breaker switchgear and also began work to correct a standard for surge voltage protective equipment.

One of the advantages of long-wavelength technology is that the radio tags can be low in cost, near credit card thin (1.5 mm) and fully programmable using 4 bit processors. Despite their high functionality, RuBee radio tags have a proven battery life of ten years or more using low-cost, coin-size lithium batteries. The RuBee protocol works with both active radio tags and passive tags that have no battery.

IEEE P1902.1 - IEEE Standard for Long Wavelength Wireless Network Protocol - will provide for asset visibility networking that fills the gap between the non-networked, non-programmable, backscattered, RFID tags widely used for asset tracking and the high-bandwidth radiating protocols for IEEE 802.11 - local area networks and IEEE 802.15 - personnel area and data networks.

The new standard, IEEE C37.13.1 - Standard for Definite Purpose Switching Devices for Use in Metal-Enclosed Low-Voltage Power Circuit Breaker Switchgear - provides guidance in evaluating switching devices, other than low-voltage power circuit breakers conforming to IEEE C37.13. According to IEEE, it was developed to aid in the design, use and installation of power circuit breaker switchgear operating at 600 V ac or less, which are used in motor control and other repetitive-duty applications.

The IEEE has also begun to correct IEEE PC62.21 Corr. 1 - Recommended Practice for the Application of Surge Voltage Protective Equipment on AC Rotating Machinery Rated 1 kV to 30 kV, Generators and Single-Turn Coil Motors. This corrigendum will involve some technical changes and will enable the standard to be converted to an interactive software document making it easier for users to apply in their own problems.
