Easy to create and hard to detect, ground loops can only be prevented through proactive design and strict NEC compliance.

The Texas State Fire Marshal's Office has released its findings, timeline and ruling on the Texas Tech fires and explosions on campus in March 2025.

Abstract: In this paper, a novel adaptive stator ground fault protection scheme based on third-harmonic differential voltages is implemented on a lab scale synchronous generator. The lab scale ...

However, this is true for only the first ground fault. A second ground fault on another phase and circuit breaker allows a phase-to-phase fault that may be of significant magnitude.
