GFLI Testing in IT Systems
Why testing and verifying ground fault loop impedance is critical in ungrounded or high-resistance grounded systems to ensure double-fault protection.
Read →The 'Cone of Protection' Myth
Why relying on a simple 45-degree cone of protection for lightning shielding is unsafe, and how the rolling sphere method works.
Read →IS Isolators vs. Zener Barriers
Why galvanic isolators are preferred over Zener barriers because they eliminate the need for a dedicated, high-integrity IS ground.
Read →VFD Output Filters: Sinusoidal vs. dV/dt
Why high dV/dt voltage spikes from VFDs damage motor winding insulation, and how output filters protect assets.
