Electrical Substation Technologies Live Online Forum March 2024

Electricity Today T&D Live Online Forums

March 21, 2024

Live Online Event

Hosted by The Electricity Forum

Forum Sponsors
Critter Guard

The focus of our Electrical Substation Live Online Forum will be substation reliability, security and stability. The changing environment in the energy sector creates a need for substation system operators to be able to robustly evaluate the impact that possible measures have on the dependability of supply of their networks. Electrical substations are is considered an important part of the power grid, and this has gained significant focus for electrical power system planners and operators to improve reliability. Our FREE Live Online Forum is a great way to learn from leading Electrical Substation professionals who are speaking on subjects about current or future technologies for reliable power substations.

45 minutes presentation includes 10 minutes of Q&A.

1:00 pm - 1:45 pm

Critter Guard

An Ounce of Prevention is Worth a Pound of Cure

Critter Guard has published their own curated statistics on the frequency and type of animal related outages for power utilities.  It's not a matter of IF you'll experience an animal outage, but a matter of WHEN.  This presentation will detail Critter Guard's efforts to prevent animal outages and keep the power on!


1:45 pm - 2:30 pm


The Importance of Through Fault Monitoring for Power Transformers

One of the more common causes of mechanical failure in power transformers comes from exposure to through faults. Most of today’s transformer protective relay systems provide comprehensive monitoring of these potentially damaging events but are rarely activated. In this paper we will define the characteristics of a through-fault, investigate various proper settings for a through-fault monitor, and present an actual case study of a severely damaged transformer exposed to this condition. We will also see examples of detecting mechanical failure in the transformer as it relates to a through-fault condition.

Vibro-Acoustic as a Fast Diagnostic Tool for On Load Tap Changers

The functioning of an On-Load Tap Changer (OLTC) is complex, since a lot of mechanisms are operating at the same time. Classic testing techniques give very little information on mechanical problems occurring inside an OLTC while in service. This presentation shows how the vibroacoustic method is used as a fast diagnosis tool to easily detect mechanical problems in Tap Changers ON-LINE or OFF-LINE, before they create an outage. We will show also how simultaneous correlation of signals recorded by Vibroacoustic, Motor Current and Dynamic Resistance Measurement (DRM) allows a fast understanding of the internal movements of an OLTC. Each of these tests provides a piece of information that creates a complete picture of the OLTC's condition. Finally, we will present a real case showing how the electric utility New Brunswick Power uses this tool to properly adjust an OLTC.


3:15 pm - 4:00 pm
