[Electricraft] Resistors suddenly not limiting current correctly

Hello everyone,

I've noticed that my resistors have stopped limiting power, and are allowing roughly twice the amount of current through that they should. Has this happened to anyone else? I'm running version 25z, by the way.
 
Sorry for the thread necro, but I've found the solution, and wanted to share it in case other users run into it:

The way electricraft's resistors work is that they apparently limit the current from EACH induction generator to whatever value you set it to. Since I had a system powered by two turbines, the current going through would be double.

The solution to this (which was not immediately obvious to me, but then again I'm kind of a noob at this) is to use shaft junctions whenever possible before converting your power via the induction generator.

Hope this helps someone!
 
Another way to possibly fix this is to feed the power coming off the induction generators into an ElC battery.

I think the only reason I'm able to stomach these jokes is I hear them so often... That said, it still hurts...

Also, feeding the power from the generators to a battery will work, but with the massive power output from the turbines, it may not be practical.

Electricraft laughs at your puny concept of power storage. While very, VERY, expensive. The auroral battery holds TJ's of power. And now there's an RF battery that when I checked last night, is measured in TRF (which I can only assume is Trillion RF). Of course the lower tiers are comparable for their cost.

Edit: I'm pretty sure the RF battery was 1.2 TRF, so basically 100,000 Resonant Energy Cells.

The other thing you can do is chain 2-4 batteries (in line, not parallel). Set up gates to detect when the last one is being drained, send a pulse to flip the switch and turn on the turbines. Set another gate to detect when the top one is full, and have it send a pulse to turn off the turbines. That way your engines turn on/off for long phases, since having them flicker would kill your fuel supply.
 
True, but the power output of both of my turbines is a bit over 1 GW. Also, I didn't think that the turbines from reactorcraft could be turned off that quickly? I'd have to pull all the fuel out of the pebble bed in order to (slowly) stop producing steam...
 
OH! I was thinking gas turbines, not ReC. I don't know of a way to "turn of" pebble beds, doubt there is one. You can slow down fission reactors using control rods.
Your best bet is probably the higher tier electricraft batteries to keep your power-loss to a minimum.
 
Well, you could use AE's precision import busses to yank all fuel out of the bed. At the moment, though, I'm getting enough coal and uranium from my boring machines in the deep dark that fuel loss isn't a huge concern. Still, I should probably invest in the highest-tier battery soon. I have the diamonds for it :D

If you want to, assuming you're just voiding your low-pressure water and not going for a closed-loop liquid system, you can potentially keep the reactor running and just let steam build up in the lines forever. Their capacity is infinite, so you can run the built-up steam through a turbine at a later time.

Onto the second thing, since this thread is both relevant and reasonably recent, Electricraft resistors are confusing.

Here's my power generation, two gas turbines junctioned and powering a generator.

Next, here's the other end of that wire, feeding into a friction heater setup. Unlimited, this motor outputs about 114 MW of shaft power. Note that there are no other motors on this wire without a resistor before them, the other 20 MW from the two gas turbines is being consumed by the ~18MW extractor setup on the left, and a couple other miscellaneous motors using less than 1MW collectively.

Now, if I try putting a 2,200 amp resistor before that motor...

...only 1,170 amps actually get to the motor.

Back at the power plant, compared to the same setup with an unresisted motor, quite a bit of power is being wasted, so I can't see any reason that 2,200 amps shouldn't be getting past that resistor.

Does anyone know if this is intended functionality, or did I hit a bug in Electricraft?
 
Hmm. The only thing I can think of is what are the current limits on your other resistors? It looks like something is using up 30 Amps somewhere up the line... Really odd.
 
The other resistors branching off the same main line in that screenshot were in the neighborhood of 1-32A, mostly powering fans and other low-power appliances.

It seems that as you add more induction motors behind resistors on the same Electricraft network, the maximum amperage that line will supply to other resisted motors starts to decline. I don't remember the exact numbers, but adding more 1A motors anywhere on the network dropped the amperage getting to the friction heater assembly from 1170 to something like 1100, 1000, 880 and so on. Unresisted motors still consumed all remaining amperage.

I fixed my problem through the heretical process of beefing up my lubricant production and replacing all of the high-power motors previously on the electricraft network with magnetostatics, which don't act oddly as more load is added to the network.
