How do you tell a pantograph is about to break or stop functioning?
1. read the manual2. arcing that results in waveform disruption that, in almost all modern locomotives, will automatically trigger a controlled transformer shutdown before damage occurs to the coils inside3. it falls down and requires the operator to stick it back up with a pole too much (particularly relevant for san francisco, where this is commonplace)what is the purpose of your question? you can visit SF and just watch them as they pass in and out of Muni's electric grid

What happens when it rains????
>>2019054is that thing insulated?what's stopping it from zapping everyone during rain?
>>2019054>How do you tell a pantograph is about to break or stop functioning?Depends on the pantograph.Usually you just need to replace the graphite when it wears with use, usually you'll notice power flicker when the wire hits the worn section of graphite, if it's really bad and you're actively drawing a high load (such as actively accelerating) when the wire goes over the worn area you might even get some pops and flashes, doubly so if you do this on a wire frog.Though you can also manage to fuck it up in a crash or something where you might need to replace the entire thing.

Electric in the poo
>>2019069the purpose of my reply is that it disrupts the waveform, this is an electrical engineering question that is arguably better done on /diy/not being dismissive, because there are studies on this. Is there any specific reason you need to know what arcing does to an AC/DC transformer?
>>2019054i don't know i am not an electrician
>>2019085>doubly so if you do this on a wire frogThis is an honest to god pet peeve of mine.Nothing pisses me off more than seeing a streetcar/tram draw power through a frog.Learn to fucking drive you dumb cunts. It's not hard.
