Inside the Digital Substation Upgrade: Migrating to IEC 61850 Ed. 2.1, Process Bus, and Interoperable Testing

From Hardwiring to Data Networking The modernization of substations is as much a communications revolution as a protection one. For decades, copper conductors carried analog signals from instrument transformers to relays and controls. Each new circuit meant more wiring, more panels, and more room...

The Problem with Birds in Substation Outages

Birds have been a problem for electrical substations since the first power distribution systems were built. The elevated components of substations create ideal perches and overhangs for birds to nest and find safety. Critical electrical substation design principles now include deterrent elements...

Grounding Transformers Explained

By R. W. Hurst, Editor

Grounding transformers are used to provide a path to ground for unbalanced load current and for fault currents on systems where a suitable ground is otherwise not available. Grounding transformers are normally constructed with one of the two configurations: Zig-Zag (Zn) with or without an auxiliary winding or a Wye (Ynd) with a delta connected secondary. The Zig-Zag connection is preferred as it is more cost effective and physically smaller...
