Preventing Losses Due to Wildlife Contacts in Electrical Substations

Intrusion of wildlife into electric substations is a problem experienced by electric utilities worldwide. In the United States, substation outages caused by wildlife contacts create a financial impact of approximately $20 to $30 billion annually based upon recent EPRI research. This impact is the...

ACCELERATING TOWARDS GREATER TESTING EFFICIENCY - A true transformer test van

Test lead management, including quality of connection and correct lead placement, is an important part of testing. Poor or incorrect connections can be the culprit for nonrepresentative results that ultimately lead to longer test times and, in some cases, wasteful investigations...

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 for error. IEC 61850 changes that model completely. By transforming measurement and protection data into digital packets, it turns the substation into a high-speed data network rather than a web of...
