Description
Three phase currents read 80 amps each. Eric Dollard then measured 80 amps in the neutral, where he had expected zero. That measurement became one of the experiences behind what he calls Gangrene Energy.
Dollard frames this talk through a lifetime of hands-on electrical work in power, transmission, telephone and maritime systems. He uses field experience, historical utility practice and measurements from real installations to argue that the modern grid behaves very differently from the alternating-current system he learned.

WHAT YOU’LL SEE IN THE FULL PRESENTATION
- See the computer-center measurement where balanced 80-amp phase currents were accompanied by an 80-amp neutral current, and why that forced Dollard to examine triple odd harmonics.
- Understand his comparison between older delta-connected utility architecture and the Y-connected systems he argues allow harmonic currents and interference to spread differently.
- Follow his case that modern electronic loads, switching supplies, inverters and digital equipment have changed both the waveform and the physical behavior of the power system.
- Separate the things Dollard says he directly measured or observed from his broader conclusions about what those changes mean for the grid.
- Hear the Q&A on electrical-engineering education, harmonic isolation, grounding, line conditioning and what he would change if the utility system were redesigned.
80 amps where he expected zero
Dollard describes an installation with 80 amps on each of three phases and then 80 amps in the neutral. He says the neutral current was dominated by triple odd harmonics rather than the 60-cycle component he expected.
From there, the talk widens into utility architecture, transformers, grounding, electronic switching and the difference between synchronous rotating machinery and electronically synthesized power. Some of Dollard’s conclusions are unconventional, but the presentation gives you the measurements and engineering path that led him there.

Eric Dollard, ESTC 2026
Dollard also returns repeatedly to a practical theme: instruments matter. Large analog meters, oscilloscopes and direct observation of machinery let him see dynamic behavior that he believes is easy to miss when a system is reduced to a flat-screen number.
Who this is for
This presentation is for power engineers, radio-noise and EMI researchers, utility-history students, Tesla and Dollard researchers and technically literate viewers who want to understand exactly why Dollard believes the modern electrical system has accumulated a new class of interference problems.
