- What’s scary is the person who posted this question probably did manage to get a registered PE designation. There’s a lot of incompetents that somehow pass the PE test. 152.186.185.14 (talk) 12:49, 15 September 2024 (UTC)
certainly, 86 is only needed in case of you shall consider blocking subsequent closing after protection trip —Preceding unsigned comment added by 116.228.159.246 (talk) 09:34, 6 May 2011 (UTC) I agree that lockout relays are used when you want to prevent reclosing of a line after it trips. Most high voltage (69kV+) relaying schemes utilize lockout relays. It should be noted that for lines that are protected below 69kV in a round about way also utilize lockout relays. For lines below 69kV a breaker/recloser typically will try to reclose a set amount of times. If it is unsuccessful it will lockout and will have to be reset before the line can return to service. —Preceding unsigned comment added by Fleckmc (talk • contribs) 20:57, 8 May 2011 (UTC)
The indicated sources are no longer available. Different definitions can be found on the Internet. The information does not correspond to IEEE C37.2-2008 (e.g. 87N and others) — Preceding unsigned comment added by Gehrig64 (talk • contribs) 18:50, 2 April 2020 (UTC)
45
[edit]I got the standart, number 45 is abnormal atmospheric condition monitor, not fire detector. Why it is here? --FearChild (talk) 12:48, 23 July 2021 (UTC)
- Because this is the encyclopedia anyone can edit and there is zero quality assurance possible, given our editorial model? I changed it for now and I have a PDF of a version of the standard, but pretty soon WP:Randy from Boise will be along and change it back again. Happy editing! --Wtshymanski (talk) 20:19, 26 July 2021 (UTC)
