Upgraded to C category.Regards, theTigerKing 19:03, 31 July 2012 (UTC)
The article would be improved if these questions were answered from reliable sources: (1) Did the system frequency drop at a certain gradual rate before the massive outage? This would indicate that there was an imbalance, with the generation deficient with respect to the load. (2) Did voltage collapse occur? This happens when the "nose curve" is encountered. Standard textbooks on power system operation analyze these questions. (3) Did protective relays fail to properly operate to drop portions of load as generation went off-line?

I question a fundamental statement of this article which calls the failures to be "separate" events. First of all the failures were only one day apart, and weather conditions were comparable. Second of all, a cascade effect which causes one failure can cause weakness along the grid, even if a secondary failure is not immediate. The article never explains how these are distinct events. Stealing of power was cited as a problem in that region also. I'm not familiar with the details. so defer to those who have better experience and data than I do. Please make the article clear if these can be truly categorized as separate events.-- 97.95.34.149 ( talk) 03:36, 30 July 2013 (UTC)
Sorry if this question may seem silly, but what is 'tripped' in this context? I'm assuming it means the line severed/ripped/teared/got damaged. It's just not entirely clear. Vince ( talk) 06:35, 31 July 2012 (UTC)
Why date is showing as 1st August.... It is tomorrow's date
The title is done very badly without the proper use of capital letters. The correct one should have been: "2012 Northern India Power Grid Failure" — Preceding unsigned comment added by 115.119.181.242 ( talk) 07:27, 31 July 2012 (UTC)
Anybody want to create a map? Speciate ( talk) 12:02, 31 July 2012 (UTC)
Hi...Check this link...this map seems correct...please upload whoever knows how to... http://news.nationalpost.com/2012/07/31/pictures-of-chaos-as-massive-india-blackout-leaves-670-million-without-power/ -- Samnag28 ( talk) 19:15, 31 July 2012 (UTC)
I'll bring my map (see above) into line with that one. Maproom ( talk) 20:40, 31 July 2012 (UTC)
The eastern states, like Bihar [my state] and Bengal were not affected by the blackout on the first day. East and Nort-East only failed on 31, the map should be updated. Chattisgarh was also affected on the second day. extra999 ( talk) 12:53, 1 August 2012 (UTC)
Reqriting now. Avoid editing. Please add content to this page under this head for the next half an hour or so. I will incorporate as much as possible. Chirag ( talk) 12:08, 31 July 2012 (UTC)
Please rename the article to something more accurate...also the blackout was limited to North and Eastern States...writing India implies as if the entire country was affected... — Preceding unsigned comment added by Samnag28 ( talk • contribs) 13:38, 31 July 2012 (UTC)
Since we are creating only one article for the blackout, then the event started on July 30th and not July 31st, as mentioned in the first line of the article...please incorporate the change -- Samnag28 ( talk) 13:44, 31 July 2012 (UTC)
Can I suggest that sections are created for each day (30th and 31st of July, as of now)? IMHO at the moment the article alternates between the events on the two days in a rather confusing manner. Obviously, apologies if this is already in hand as part of the current edit. John259 ( talk) 13:01, 31 July 2012 (UTC)
I Think there were two separate articles on the black out. Too much editing happening. Separate events. affecting separate parts of the country. Chirag ( talk) 13:05, 31 July 2012 (UTC)
Why is this page flip flopping? especially since I left an in-use tag? There were two separateblackouts on two different days impacting different parts of the country. Chirag ( talk) 13:13, 31 July 2012 (UTC)
There is absolutely no reason to delete this page. This is censorship, plain and simple.
Agree on the "Power Grid Failure" vs "blackout". Also, the article currently begins "The July 2012, India blackout began on 31 July 2012 at 1:02 pm local time in India, affecting 14 states.[1] This was the second consecutive failure in as many days."
Then, it really began on July 30? Sure, this is an ongoing, developing event - but it seems like the whole intro paragraph should be redone more clearly, imo. — Preceding unsigned comment added by Trep26 ( talk • contribs) 16:03, 31 July 2012 (UTC)
Can we have two separate sections- viz one each for 30 and 31 July 2012 in each section, how lives were affected and the response to each one of them. Its all messed up.Regards, theTigerKing 17:37, 31 July 2012 (UTC)
So, is this article on both blackouts? I have no real strong feelings one way or the other, but are they really the same event? Did power get restored and then go out again? Speciate ( talk) 16:53, 31 July 2012 (UTC)
I have done copy editing on the entire article and I do believe that is better worded than it was before I edited it. I would remove the Copy Editing notice, but I want to make sure that other editors are happy with what I've done before I remove the notice. Peace! Aleksandar Bulovic' ( talk) 17:12, 31 July 2012 (UTC)
Can we really believe these mega-numbers of people affected? The newspaper articles contradict themselves. We say that 600 million people were without power today, but how many of them actually had power in the first place? For example, the Guardian article we quote, after delivering the huge numbers, goes on to say that "A large minority of those in the blackout zone have never been connected to any grid". So when quoting these numbers we should say that so many millions of people live in the affected area, not that they are all affected. I'm going to dive in and qualify some of these statements, but in the long run I hope we can find the numbers of actual subscribers affected (plus the non-subscribers who were on stalled trains or in darkened hospitals, of course). -- Heron ( talk) 18:16, 31 July 2012 (UTC)
Just out of curiosity ... how late is this monsoon? I'm seeing what seem to be relevant news stories from July 2 and July 5 hoping for the monsoon to come. [2] [3] How unusual is it for the monsoon to be so far delayed? Wnt ( talk) 20:08, 31 July 2012 (UTC)
I'm asking this because the area affected by the power outage nearly surrounds the country of Bangladesh.
Is Bangladesh's power system so independent of India's that it was unaffected by this huge power outage OR is information about Bangladesh simply not included on the map? Wanderer57 ( talk) 20:55, 31 July 2012 (UTC)
The result of the proposal was moved to 2012 India blackouts. -- regentspark ( comment) 19:59, 9 August 2012 (UTC)
July 2012 India blackout → July 2012 India blackouts – I'd like to see the name of the article brought in line with the actual events, which as far as it is being written seems to be two distinct blackouts. It is August already in India, that limits the name or scope of this article. Since the article is on the Main Page ITN section, I am hesitant to unilaterally make this move. Speciate ( talk) 20:58, 31 July 2012 (UTC)
The eastern states, like Bihar [my state] and Bengal were not affected by the blackout on the first day. East and Nort-East only failed on 31, the map should be updated. Chattisgarh was also affected on the second day. extra999 ( talk) 13:47, 1 August 2012 (UTC)
I added back in "Loss of 400 kV Bina-Gwalior link due to mis-operation of it's protection system" because while the link was heavily loaded, it wasn't overloaded. The grid conditions tricked the protective relaying into thinking there was a large fault (short circuit) somewhere else on the grid (zone 3 protection) and tripped the line off. Records indicate that there was no fault, so the protective system triggered when it wasn't suppose to operate. Zone 1 is primary protection, Zone 2 is backup to Zone 1, etc — Preceding unsigned comment added by 142.9.1.100 ( talk) 14:06, 29 August 2012 (UTC)
The States affected are listed in dot points:
states on the northern grid: Delhi, Haryana, Himachal Pradesh, Jammu and Kashmir, Punjab, Rajasthan, Uttar Pradesh, Uttarakhand
Delhi is not a State!

The first paragraph of the section "Sequence of events" ends with the sentence "The Northern and Western Regions' Load Despatch Centres (LDCs) requested that the Northern region shed load and the Western region reduce generation to unload the power line, but neither utility failed to do so adequately."
Neither utility failed to do so adequately? Is this meant to say "neither utility did so adequately"? 129.242.242.125 ( talk) 12:37, 7 May 2024 (UTC)
