@engineerlondon.bsky.social , Do you have a nostalgic or favorite relay, not necessarily the fastest or the most sophisticated but one you fondly remember? Maybe the first relay you ever commissioned. For me, its the Brown Boveri LI41 overcurrent-start distance relay. Compact and all mechanical.

@engineerlondon.bsky.social /2 SWER is derived from a 33Kv 3-phase backbone where one wire (phase) spurs off for kilometres to feed a series of transformers. Here is this fix, you can hear in the background the buzzing on the radio receiver suddenly stop. www.youtube.com/watch?v=-5R_...

@engineerlondon.bsky.social Thought this may be of interest. An amateur radio High Frequency receiving site set up some distance from the city has long suffered with electrical noise from the site's electrical supply which is 19Kv Single Wire Earth Return (SWER).
