The reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.

NASA Space Shuttle’s Return to Flight: The Untold Electromagnetic Backstory
After the tragic 2003 Columbia re-entry accident, computational and experimental electromagnetics were ultimately applied to foster the development of a new NASA Ascent Debris Radar (NDR) for the remaining 22 Shuttle missions.
IEC 62368-1 AC Mains Port Protection Component Requirements
This article describes the MOV circuit design sequence for the AC mains port overvoltage protection of pluggable type A equipment.
Radiated EMI From A Buck Converter
EMC radiated problems in HF/VHF ranges are typical in products with switching-mode power supplies (SMPS) as for example flyback and buck converters. Usually no high power is needed to radiate signals well over the legal EMC limits.
Let’s Talk About Obtaining NRTL Approvals More Effectively
The usual experience when working with a NRTL is that projects are, more often than not, late, costs are overrun, and certification reports often inaccurate. This is not always the fault of the NRTL.
Improving Medical Devices with Force Sensing Technology
Design engineers integrate force sensors into medical devices to create smart tools that produce quantifiable data.
