#6 - What does electrical insulation actually do? (Part 3) - Solids and Liquids

What actually happens inside insulation before it fails? Most insulation problems do not start with a visible failure. They begin inside the material, where small defects change how the electric field behaves. A tiny void, a small amount of moisture, or a minor imperfection can create a weak point that slowly develops over time. In this episode, we break down how solid and liquid insulation behaves under electrical stress. You will learn how materials like XLPE, epoxy, paper, and transformer oil respond to electric fields, how partial discharge begins inside defects, and how long term processes like electrical treeing lead to failure. We also cover why moisture has such a strong impact on insulation performance, how aging changes material properties, and why many failures appear sudden even though they have been developing for years. This episode is designed for new technicians, apprentices, and anyone entering the electrical industry who wants to understand how insulation behaves inside real equipment. By the end, you will be able to look at cables, transformers, and bushings and understand how internal insulation degrades and why small defects can lead to major failures.

#5 - What does electrical insulation actually do? (Part 2) - Air as an Insulator

What happens when air stops acting like an insulator? Air is everywhere in power systems. It separates conductors, surrounds equipment, and provides the clearances that keep systems operating safely. But under the right conditions, air can quickly transition from an insulator to a conductive path. In this episode, we break down how air behaves under electrical stress. You will learn how ionization begins, how avalanches form and grow, and how those processes develop into corona, streamers, and full electrical breakdown. We also cover how geometry, spacing, pressure, and environmental conditions influence when and where breakdown occurs. This episode is designed for new technicians, apprentices, and anyone entering the electrical industry who wants to better understand high voltage behavior in real systems. By the end, you will be able to look at clearances, conductors, and substation layouts and understand why air insulation works in some conditions and fails in others.

#4 - What does electrical insulation actually do? Part 1

What does electrical insulation actually do? Most people think insulation is just a material like rubber, porcelain, or oil. But in reality, insulation is a system designed to control electric fields. When you understand how electric fields behave, insulation failures stop being mysterious and start making sense. In this episode, we break down the fundamentals behind how insulation really works in power systems. You will learn why geometry often matters more than voltage, how electric fields concentrate at weak points, and what actually happens during electrical breakdown. We also introduce key ideas like partial discharge, contamination effects, and why insulation ratings are more than just numbers on a nameplate. This episode is designed for new technicians, apprentices, and anyone entering the electrical industry who wants to build a strong foundation in real-world power system behavior. By the end, you will start to see electrical equipment differently and understand how cables, insulators, bushings, and transformers are designed to survive under high voltage conditions.

#3 - Darkness to Light: The Fight for Rural Electrification

By the early 1930s, nine out of ten American farms were still in the dark. Cities glowed with electric lights, radios, and neon signs, but out in the countryside, nights ended with kerosene lamps and wood stoves. This episode takes you deep into the forgotten struggle to bring electricity to rural America; a fight that wasn’t just about technology, but about power in every sense of the word. We trace the story from the shadow empires of holding companies that controlled three-quarters of the nation’s electricity, through their dramatic collapse in the 1930s, to the creation of the Rural Electrification Administration and the farmer-led cooperatives that finally lit up the last dark corners of the map. It’s a story of money, politics, and class; but also of dignity, connection, and what it means to share progress. Perfect for: History buffs, energy nerds, and anyone who’s ever flipped a light switch and wondered what it took to make that possible.

#2 - AI’s Energy Hunger and the Return of Nuclear Power

What do AI and nuclear power have in common? More than you think and your future career may depend on it. In this episode of the Prime Systems Academy Podcast, we dive into the surprising link between artificial intelligence and America’s aging power grid. From the massive energy demands of AI systems to the urgent need for 24/7 dispatchable power, we explore why nuclear energy is making a serious comeback and how recent policy changes could spark a once-in-a-generation transformation of the U.S. power industry. Whether you're an apprentice, a journeyman, or someone just curious about where the world is headed, this episode unpacks: * How AI is straining the grid * Why renewables can't meet the 24/7 demand alone * The rise of small modular reactors (SMRs) * Trump's bold push to reboot nuclear policy * And why the electrical field is about to explode with new opportunity If you want to be part of the crew building tomorrow’s energy infrastructure, don’t miss this one.
