Talk:Fault indicator

Better photo needed
A blown fuse indicator may indicate a line fault, but if you happen to see teh real fault indicator on a line, please snap a photo and upload it to Commons! We've got several external links that show what we're looking for. --Wtshymanski (talk) 19:42, 14 March 2014 (UTC)

Petersen coil reference
There is no wikipedia reference to petersen coils

Also seem to be called arc suppression coils in Europe, basically an inductor to ground that approximately resonates with the capacitance to ground of the line, the basic theory is that with any single fault to ground, the current flowing in the "neutral" line through the petersen coil is quite low, and the fault current is low enough that any arc is extinguished, so the breakers/ fuses won't be tripped, and supply will be maintained , at the same time the supply authority will be notified of the voltage on the petersen coil, and can arrange to have the fault fixed.

The first hit on https://www.google.com.au/search?q=petersen+coil is quite informative. Salbayeng (talk) 00:59, 11 May 2016 (UTC)
