I guess I should consider myself lucky that it didn't blow me the f**k up when I hooked it up then.
Thought that that kinda thing would've happened when I upgraded the system to medium voltage; so I made transformer upgrades for all the machines. then added some more machines before adding the transformers and realised 5 mins after I hooked them up they should've taken out a sizeable chunk of the part of the base they were in.
A bit of an off-topic question, but I think still (kinda) relevant; are we still referring to packet sizes as difference in voltage? How does EU per packet (EU/p) differ in practicality (how they affect machines) from EU per tick (EU/t). Are packets applied per tick, and so making the two units synonymous or is there some fundamental difference in how they affect IC2 machines?
I get the feeling I should start a new thread with this question...
Choco could probably elaborate on why transformers are still "totally necessary." Here's my less-informed info:
I do use transformers because I don't want to update to the mystical e-net one day and craterize my base. More important on a daily basis, it also (as I understand it) allows me to send larger amounts of power around with less cabling: I can pool smaller threads of power into a transformer, up-transform it, and send it away. Afaik cables are still limited to their maximum eu/t throughput, so unless you want tons of cables running in parallel here and there, transforming makes sense.
For your ic2 energy-net questions: from what I understand, "packets" are temporarily(tm) shelved. When you send 128 eu/t down the line, you're for all intents and purposes losslessly sending 128 packets of 1 eu. (Someone may correct me and say that "1 packet of 128 eu/t is more accurate.")
This changes a bit in GregTech if you're planning to use that: power is definitely sent in packages (amps) of energy (volts). So a machine may want, say, 148 eu/t to run, and it could get that power on a cable if that cable supported a) 128V and b) 2 or more amps (and there was a power-producer on that cable able to output at least 2A of 128V). In this scenario, a "packet" of 128V would be sent, plus a second packet of 20V (simplified a bit since there is lossiness on these cables and machines to account for).
I see I'm blurring the distinction between eu and V a bit above. Sorry about that. tl;dr: Sending 2A / 128V correlates to 256 eu/t.
