Blue Alloy wire and distance

Redpower Blutricity Blue Alloy Wire

Best Answer Hippieshaman , 21 March 2013 - 07:02 AM

Assuming you know math, here is a few formulas for calculating the power loss.

 

The limit they are talking about, is that the wire can't transfer voltages higher than approx 107.4 volts, there is a HV cable that you can use in conjunction with transformators to increase this limit.

 

as for calculating the power loss, here is some formulas:

 

Volt = U

Resistance = R

Ampere = I

Watt = P

 

P = U*I

U = R*I

I = U/R

We already know the max Voltage and the resistance, so we want to find the loss per block in relation to Ampere

I = 107.4/0.02X (Where X is number of blocks)

We need to convert Ohms to milliOhms so the calculator wont have to divide by numbers less than 1 to get the correct result

mA loss per block = 107.4/20X

This gives us a loss of approx 5.37 mA per block, which contrary to the article isn't very much, you would lose 1.02A over a distance of 190 blocks, which is (assuming the Voltage is maxed out from the source) about 110W

 

I think the blue alloy wire also have a loss in voltage over distance that is not in this equation, but I don't have time to research that right now, this would further increase the loss proportionally to the distance traveled.

 

Someone correct me if my own math is off... its 7AM and I haven't done these kinds of equations in years..

I never took electric physics in college, so this section from the blue alloy wire article confused me.

 

Blue Alloy Wire has a limit on packet size at approximately 107.4 volts...
Blue Alloy Wire is also lossy, having a resistance of  0.02 ohms per block. Over long distances, this can result in large power losses, especially if high amperes are flowing the wire. To minimize this losses it's recommended to use more wires instead of only one.

 

What exactly does this mean? How long is a "long distance"? Why does having more wires help? Does daisy changing battery boxes help like in Industrial craft?

 

Any tips would be appreciated.

It's relatively spot on, though the game does employ some sort of additional energy loss.

Alright thanks, as long as that "additional energy loss" isn't too extreme I guess I don't have to worry too much with my current setup. Still, lets say I did want to transmit blutricity over 200 blocks? Is there anything I could do to extend the distance, short of converting it to higher volt wires (which doesn't really seem effective unless you have a huge about of power being generated).

For energy distribution methods, I highly recommend using EU to cover the long distances, then convert it to Blutricity at the destination. I highly doubt you will have much energy left over after attempting to transport Blutricity for 200 blocks.

Or you could set up some sort of battery and enderchest setup. The batteries would charge, get sent to the enderchest, and discharge in the system after being removed from the enderchest.

I'm using Direwolf right now, so I don't think that's very easy to do without power converters. Anyone know if Direwolf will add it in the future?

I was thinking something like that, sending the batteries on my minecraft network, but yeah enderchests are probably a better idea most of the time.

The BT Battery-Ender Chest method is probably the best method of transporting Blutricity over a long stretch of space, and possibly the only viable method. Even with the Power Converters mod, Blutricity can't be easily converted to any other form of power and then converted back again, as there is no Blutricity Producer block or other method of taking another form of power (e.g. EU) and turning it into Blutricity. If another form of power is desired, you could use a Blulectric Engine to make it into MJ, but if you need Blutricity for something, the battery method is most likely best.

 

To my knowledge, the Direwolf pack operates on the mods that Direwolf uses, so if he's not planning on adding Power Converters to his world in the foreseeable future, then it probably won't be added to the pack.
