compressible material in the stack up, as polymers or fiber washers. Back in the day, I learned my earthing (EU) or grounding (US) for high power equipment from a German expert at LGA Landesgewerbeanstalt Bayern in Nürnberg and the guidance I received was to use star washers on plain me...
Habitability and design: Radical interdependence and the re-earthing of citiesHighlights Earth has been exiled from the city; this civilizational anomaly needs to be addressed. The exile of Earth from the city has caused a crisis of the Occidental modes of habitability. New modes of dwelling can...
I've given myself a regular internet headache trying to understand the relative merits of spring vs star washers for use on an earth stud for protective earthing purposes. What is the conventional wisdom and justification? I know I can trust you folks to be above a simple "we've always do...

This paper is based on the 2018 Neil Smith Lecture presented at the University of St Andrews. It considers the plantation past/futures of Sapelo Island, Georgia, one of the Sea Islands forming an archipelago along the US Southeastern coast. I work through the abolitionist efforts of the ...
High-speed reclose earthing arrangementPURPOSE: To provide a high-speed reclosing grounding device capable of interruption induced current surely in a phase of a preceding one-line ground fault occurring, even if a following ground fault happens in another phase after the occurrence of the ground ...
even if a ground fault is followed by another one occuring in another phase while it is being operated to open a circuit in the phase of the fault, can surely cut off induced current in the phase of the fault and allows a circuit breaker to reclose the circuit at high speed thereafter...

An elastic earthing plate (1) comprises a base (11) comprising buckling portions (12) respectively positioned at two sides of a case receiving space for buckling to corresponding sidewalls of a track in receiving space for positioning; and two arms (13) extending from two side of buckling ...
