GregTech's Machines exploding due package overload?!

[iMontouch]

hey there!

we have some problems with the OverLoad Package but we are sure, that they are not directly bound to only this package. Or maybe they are?

We get our energy from some solar panels which are connected to a MFSU. The 2048 EU/t of this unit are being put into an HV-Transformer (using the HV cables, of course). Then the energy is transfered down again using an MV-Transformer. This unit provides energy for several units including two industrial blast furnaces. The problem is, that we dont have enough energy for the IBF (insufficient energy line). So (as we know it from FTB Ultimate) we placed another MV-Transformer.

The result was an explosion of the connected IBF.

We are sure, that we have 128 EU/t over, we cant test it, since the EU-Reader is broken in this IC² version, but we can make sure.

Do you know why the machine cant handle more packages of 128 EU? Or IS is the problem?

Help will be highly appreciated and I will deliver additional information as needed!

Put a CESU (128eu/t?) next to each IBF. Keep your setup as it was Initially.

The MFSU is only sending packets in size of 2048 that get down converted twice. There is probably a tick in between the conversions and the buffer storage in the machine is tiny. Either that, or another machine on that net is drawing. The CESUs will give you better room for forgiveness.

Yes, there are more, but less then 16 machines with a need of 128. Maybe 8?

Just to be sure that I got this right:
1 MFSU, 1 packet of 2048 EU --> HV-Transformer, 4 packets of 512 EU --> MV-Transformer, 16 packets of 128 EU
(minus the cableloss)

You mean to get a CESU for every of gregs machines set up? I dont remember that this was needed back in 1.4.7 FTB Ultimate..

Assuming you're using ic2 exp, then the reason the IBF exploded is that you provided more power than it could handle. Two MV-Transformers on the same line will give you 128 + 128 = 256 total eu on the line. Runo's solution above will make sure that each IBF is getting 128 eu.

 

[iMontouch]

you sure about that? We assumed that another transformer just adds another package to the cable. Like that: 1 Transformer sends 8 packages of 128 EU and the other sends additional 8 packages.

So we could use Runo's solution, but it should also work with just one MV-T with enough intake to give enough packages for every machine?

Thank you guys btw!

IC2 has changed. Power is no longer sent as packets. Each energy producer is summed. So 4 generator's producing 10 eu/t will total 40 eu on the line. Any machine that has a max of 32 eu/t will explode. Also, cables have changed. Tin can hold as much as 32 eu, copper 128 eu, etc...

okay that makes sense now. (we were unable to find any documentation for that)

so, why is this working then? :/

Spoiler

3 LV-Transformers feeding several E-Furnaces (IC², not the gregtech versions which exploded in the same setup)

IC2 has disabled explosions until they can get the e-net working properly, but Greg hasn't.

 

[iMontouch]

okay. Now it all makes sense! Thank you!

Just to be sure that I got this right:
1 MFSU, 1 packet of 2048 EU --> HV-Transformer, 4 packets of 512 EU --> 4x MV-Transformer, 16 packets of 128 EU

Added 4x prefix to mv transformer based upon 1.5.2 .... guess its still the same. The mv transformer can handle only 1 packet of 512 eut...so ypu need 4 to pass all the current down! Othersise the hv transformer only outputs 1 packet / tick not 4

General advice- Please upload some screenshots of your build/problem areas.

If theres walls ect in the way- rebuild in creative instead of demolishing half your legit stuff- as long as we can see what your doing.​

How the new Enet works

• you CANNOT send multiple packets down the same line.
  • This is the biggest change from vanilla IC2
  • Meaning that if a generator makes 10Eu/t- 2 gennys will make 20Eu/t
    • Old IC2 will send this as 2x10Eu/t packets
    • New IC2 will send this as 20Eu/t.
  • So 2 MV transformers down the same wire will be 256Eu/t- High Voltage. (probably why the whole lot blew up).

Use a different wire for each transformer. Make sure they don't short circuit.
Voltage upgrade are pretty useful too.

You mean to get a CESU for every of gregs machines set up? I dont remember that this was needed back in 1.4.7 FTB Ultimate..

You needed a dedicated MFE back then. -or something equivalent to 128Eu/t (such as 8 thermal gens)
Though you can upgrade the internal storage of the machine to save needing an external block.
