| Oct 24, 2020 at 21:49 | comment | added | ZZ1 | All the affected households were being served by the same transformer. It might not be because of the transformer but that's what I thought. Could you suggest some keywords that I could search, that might help me enhance my understanding? | |
| Oct 24, 2020 at 21:44 | comment | added | Marcus Müller | hm, how do you know it's a failure of the transformer? the fact that many households were affected might indicated that it was a surge on the common higher-voltage line. | |
| Oct 24, 2020 at 21:42 | comment | added | ZZ1 | In my town, a few days back, the surge of voltage (failure of the transformer) caused many houses to lose useful appliances. The electric poles in my county going to the transformers mostly contain 3 wires (I think 3 phase current), but each house is provided with a phase and neutral wire. Hence, I believe that the transformers might be delta (primary) to Y (secondary). | |
| Oct 24, 2020 at 21:23 | comment | added | Marcus Müller | Do you have any context to this? Like, how does that question arise? There's quite a few things, but I'd guess you'd want to rule out "cat overlords playing on substation operator table"... | |
