Using Lightning to Test Power Grid Health
A Swedish researcher has developed a new method of employing lightning and other high voltage currents to benefit power companies. Normally considered disruptive to transmission lines and destructive to the power grid, these so-called natural transients could be used instead to monitor the wear and tear on power components. “We can use these high voltages to obtain more … [Read more...]
Risk of ESD-Sensitive Devices in Proximity to ANSI/ESD STM2.1-Compliant Garments by Field-Induced Model Discharge
Bob Vermillion CPP/Felow Certified, ESD Engineer-INARTE RMV Technology Group, LLC A NASA Industry Partner During ESD assessments, it is not uncommon to see personnel wearing wool, silk, cotton, polyester blends and static control overalls (ESD Garments). Some ESD garment types consist of an embedded conductive grid network (Figure 1) in combination with cotton or polyester … [Read more...]
