Substation Physical Security Back on Front Burner
Sam Sciacca’s article, Substation physical security back on front burner, describes how physical security and cyber security must dovetail at substations. Increased theft of substation materials, particularly copper and steel, and the threat of terrorism have led the power industry to approach this issue in a more sophisticated manner. Sciacca offers up-to-date thinking on the [...]

Addressing Time Synchronization Issues and Related Standards Work
Sam Sciacca’s article, Addressing Time Synchronization Issues and Related Standards Work, advises consulting specifying engineers on how to ensure that the intelligent electronic devices (IEDs) they select for clients will meet vendors’ claims for performance with regard to time resolution. The article caps a three-part series; the first article looked at Designing a Time Synchronization [...]
Managing the Magnitude of the Smart Grid
Utilities, industry, policymakers and even consumers must not underestimate what is being undertaken in the smart grid. It’s not just a next step; it’s an interrelated range of steps—and, sometimes, leaps—that are all pointed toward the same set of revolutionary goals. It’s that potentially overwhelming magnitude of the enterprise that makes the emerging smart grid [...]
Assessing Vendor Claims on Time Resolution in IEDs
Sam Sciacca’s article, Assessing Vendor Claims on Time Resolution in IEDs alerts consulting specifying engineers to the vagaries of assessing vendors’ devices that accept time inputs because few vendors provide specifications that reflect absolute accuracy of the events record produced by each of their IEDs. Opportunities abound for introducing errors in a system between the [...]
Designing a Time Synchronization Source
At distribution voltage levels, accuracy in the range of 10 to 20 milliseconds may be sufficient and provided by a local clock. When time synchronization requires a resolution of plus or minus one millisecond, an external time source is needed, such as a GPS or WWV receiver. Accuracy in the microsecond range requires synchrophasors. Sam [...]
