The Lights are Still On!

Don A. Genutis Columns, In the Field, Summer 2021 Columns

The technician’s job is usually to ensure the lights are on, but we often need to shut a facility down to perform much needed outage-based maintenance. This switching activity is often straightforward, but when the electrical system is complex and several issues exist, unexpected events can occur. Our team was recently fortunate to be awarded a major contract to provide …

Best Practices for Setting Transformer Differential Protection CT Compensation

Steve Turner Columns, Relay Column, Summer 2021 Columns

Historically, CT connections compensated for the phase shift across a transformer when applying differential protection prior to the advent of numerical transformer protection relays. For example, a delta-wye transformer would have wye connected CTs on the delta side and delta connected CTs on the wye side. The delta connected CTs have the same connection as the transformer delta connected winding …

Key Points of NFPA 70E’s Safe Work Practices

Power Factoring Medium-Voltage Breakers

Rick Youngblood Features, Summer 2021 Features

A test technician’s toolbox can never have too many options. The more ways we can detect or confirm a problem in a piece of equipment, the better. Early in my career at Duke Energy, I was never satisfied with just one test result indicating a problem, and I often second-guessed myself as to whether the equipment was bad or if …

Advancements in the Industry: Simplifying the Testing of Automation and Control Systems

Eugenio Carvalheira and Andreas Klien CAP Corner, Summer 2021 CAP Corner

During the life cycle of a substation automation system (SAS), it takes considerable effort and time to test the communication, interlocking logic, and proper operation of all signals transmitted to supervisory control and data acquisition (SCADA) systems. In a substation that makes use of IEC 61850 communication, all the engineering and configuration data can be saved in standard-format files — the …
