Update Announcements are Catagorized as Follows: Specifications by CSI Division; Guideline Elements by Section Letter, Supplemental Resources by Subject Matter, and General. http://www2.mdanderson.org/depts/cpm/standards/rss/odg_electrical_updates.xml Revised 1.01 E. to read as, "Section 26 23 13 – 600 Volt Generator Paralleling Switchgear". Revised 1.03 C. 8 to read as, "IEEE 446 - IEEE Recommended Practice for Emergency and Standby Power Systems for Industrial and Commercial Applications". Revised 1.03 C. 10 to read as, "IEEE 666 – Design Guide for Electric Power Service Systems for generating Stations". Added 10.7 A to require, "COORDINATION WITH UTILITY COMPANY A. The Contractor shall, on behalf of the Owner, coordinate with utility company in providing required information for reviewing and assuring that installation will meet utility requirements as well as Electric Substantive Rules set forth by Public Utility Commission of Texas, which governs technical requirements for interconnection and parallel operation of on-site distributed generation and utility company distributed generation. Added 2.03 L to require, "L. Closed transition. When designing a closed-transition system, it is imperative that the system be designed with interlocks that prevent the inadvertent and indefinite paralleling of sources. The following design rules should be used when designing closed-transition system. 1. Closed-transition switchgear should be designed such that manual transfers are manually initiated and automatically interlocked. This prevents utility sources from being paralleled for an excessive amount of time. This transition shall take place within the range of 100 milliseconds, depending on specific utility requirements. 2. Closed-transition switchgear should be designed with a non-defeatable safety-circuit timing relay, which will cause source disconnection within a predetermined time if the sources are manually paralleled, or the closed-transition interlocking scheme fails to perform. For example, a timing relay that opens the tie breaker if both utility mains are closed for 10 sec would serve this function. 3. Where closed-transition automatic transfer switches are specified, a shunt-trip circuit breaker on the normal feeder could be specified to force the normal feeder to open in the case of a failed-closed transition. 4. All of the functions noted in 1-3 above should be alarmed and annunciated.
