Advances In Transformers Ratings Using Fibre Optics

ADVANCES IN TRANSFORMERS RATINGS USING FIBRE OPTICS

Presented By: Jerzy Kazmierczak Product Technical Manager Hitachi Energy TechCon 2022 For a long time, the transformer industry did not have the solution which could be used to measure the winding hot spot directly. The solution with the current transformer called “thermal image” which was connected to the hotspot gauge was commonly applied to monitor […]

Can We Securely Communicate Wirelessly in Substations?

COMMUNICATE SECURELY IN SUBSTATIONS

Presented By: Thomas Schwartz General Electrical Industrial Communications Senior Technical Application Engineer TechCon 2022 In the world of electric utilities, privately owned communication networks remain the vehicle of choice for interconnecting assets in the Field Area Network (FAN). Currently, thousands of utilities in the US are “managing multiple—sometimes more than a dozen—wireless networks in support […]

Individual Capacitor Monitoring for Intelligent Capacitor Bank Diagnostics

MONITORING INDIVIDUAL CAPACITORS

Presented By: William A Munn and Joshua Nikkel General Electric and Southern Company Services TechCon 2022 Capacitor bank monitoring is typically limited to the whole bank, per phase, or per string monitoring. The lack of granular information about individual capacitors hampers attempts to predict capacitor bank failure and contributes to capacitor bank maintenance that is […]

SUBSTATION GROUND GRID TESTING AND MAINTENANCE

Presented By: Ronald Proffitt Technical Consultant North American Substation Services TechCon 2022 Arguably, the two most important substation/plant components related to Safety and Reliability are the station battery and ground grid. If they do not function correctly, personnel Safety and equipment Reliability are at risk. In recent years with the focus on FERC PRC guidelines, […]

Understanding Legacy Transformers for Potential Extended Life

LEGACY TRANSFORMERS

Presented By: Brian D. Sparling Dynamic Ratings Inc. Senior Technical Advisor TechCon 2022 It is important for transformer users and asset managers to be adequately equipped to assess the condition of legacy transformers in their utility/organization as a basis for making critical decisions about operations. In other words, classifying candidates and priorities for, repair/rectification of […]
