Energy Talks

This Energy Talks episode explores using dynamic resistance measurements (DRM) for safe, accurate timing tests on circuit breakers grounded on both sides. OMICRON circuit breaker testing expert Andreas Nenning shares practical insights on why this method is essential for grounded conditions, the impact of grounding resistance, and how to avoid critical threshold errors.

In this episode, OMICRON's OT security expert Simon Rommer, along with security research experts Andreas Happe and Siegfried Hollerer, discuss their work and experience with the open-source OWASP OT Top 10 Project, which addresses critical industrial cybersecurity challenges affecting OT environments. Simon and his guests describe how critical cybersecurity risks are mapped directly to global frameworks like IEC 62443 and NIST, providing actionable countermeasures and a shared vocabulary for improved industrial resilience.

Every diagnostic test leaves a digital history—from settings and firmware to maintenance documentation. As substations modernize, preserving this contextual history becomes vital for engineers, cybersecurity teams, and auditors years down the road. This episode of Energy Talks kicks off a new miniseries exploring how software supports compliance readiness in power system testing and digital substation operations. In Part 1, OMICRON Regional Training Manager Will Scheibe explains why preserving device history matters and how OMICRON’s ADMO software with its InSight data visualization platform supports structured data across the asset lifecycle.

Bushings are critical power transformer components, responsible for nearly 40 percent of failures. In this Energy Talks episode, OMICRON experts Hannes Rothleitner and Jakob Hämmerle explain how modern bushing diagnostic methods detect early insulation degradation. They highlight the industry shift toward combined testing techniques to uncover hidden flaws and discuss the future of the field, emphasizing high-quality data interpretation for better decision-making.

Reclosers have long been essential for protecting distribution networks and restoring power after faults. Today, they are evolving from standalone protection devices into coordinated system actors that combine protection, automation, communication, and control. In this episode, OMICRON application engineer Alex Auman, who specializes in reclosure and protection testing, explains how reclosers help utilities integrate distributed energy resources (DER), improve reliability, and enable self-healing grid concepts. Alex describes various automation schemes that help utilities keep more customers energized during faults and disturbances and highlights the growing importance of comprehensive testing and validation.
