IEEE approves new standard

The Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) Standards Board has approved a new standard for automatically reclosing line circuit breakers on transmission and distribution (T&D) lines. It also approved the start of work on two other T&D standards: a new guide to protective relay applications and the revision of a standard on lightning performance. A new standard that will compare distribution equipment in North America and Europe was also begun. The new standard, IEEE C37.104 (TM), “Guide for Automatic Reclosing of Line Circuit Breakers for AC Distribution and Transmission Lines,” describes current practices for automatically reclosing transmission and distribution lines, as well as reclosing considerations and coordination practices.

New software for A3 ALPHA meter

ABB has released MeterIT Metercat Software version 1.2, which reads ABB’s MeterIT A3 ALPHA meter. A new feature of the software is the ability to program Itron’s 50ESS ERT, a radio-based module recently integrated under-the-cover of the meter. (Metercat stores meter readings for later retrieval and saves meter data to reports in standard HTML format.)
