In this episode of Energy Talks, we dive into high-voltage and circuit breaker testing under Latin America's unique field conditions. OMICRON power system testing expert Yefersson Cañon shares first-hand experience working with regional utilities and industrial plants. He explores local maintenance requirements, technical standards, and safety practices. Discover real-world problem-solving strategies, the role of grid diagnostics in disaster recovery, and the future trends shaping the region’s power sector.
In this episode of Energy Talks, OMICRON Cybersecurity Expert Simon Rommer launches an essential new mini-series focused on operational technology (OT) cybersecurity countermeasures in the power industry. Instead of just chasing the latest tech trends or treating security like a generic checklist, this series takes a step back to ask a fundamental question: Countermeasures—what for, and against what?
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.
