The High Voltage Transformer is used to turn Extreme Voltage (EV) EU current into High Voltage (HV) and back. Only HV Cable can carry EV. HV Cable carrying EV has 8 times the loss vs Glass Fibre Cable carrying HV.

(EV is 513-4096 EU/t)

(HV is 129-512 EU/t)

(MV is 33-128 EU/t)

(LV is 1-32 EU/t)

EV current, such as nuclear reactor current, must be wired into the EV face (the 3-dotted one), while HV current can be wired into any other face. By default, the Transformer outputs HV current. A Redstone signal must be applied to it in order to make it reverse flow, thereby emitting EV current from the EV face (the 3-dotted one).



When using any Transformer, remember that the 3-dotted face means higher current and the 1-dotted face means lower current. You can change the direction the 3-dotted face is facing by right-clicking a 1-dotted face with a Wrench.

Converting to HVEdit

In order to convert EV to HV, you must point the cable carrying EV from another HV Transformer to the 3-dotted face and then link a cable to one of the faces with a single dot. Then that cable will be carrying HV that you can link to an MFS Unit or an MV Transformer.

Converting to EVEdit

In order to convert HV to EV, point the cable carrying HV from an MFS Unit or an MV Transformer to one of the one-dotted sides and then link a cable that can carry EV (HV Cable) to the 3-dotted side. Do not forget to apply redstone to the HV Transformer.

    • Expanding on thoughts and trying to provide as much information as possible, 4 HV solar arrays create 2048EU/t BUT the packets are still 512EU...
    • How can you use all the 2k EU/t??? Make huge amounts of stuff that need power. like  1 energy condensors 2 factories 3 (for servers) buisnes...

    • It's called '3x ins' cable in the game. So there is nothing to fix. Thanks brain! It's quite obvious that I wasn't firing on all cylinders at ...
    • Yes there is if its not working 9how did you craft it)
