For you efficiency freaks using LV-HV turbines in the early electric age:
Extended my calculations for transformation efficiencies and drew some conclusions that might be interesting for a few of us. This considers both efficiency of generators, transmission losses and minimum cable losses (some cable losses are impossible to avoid when doing 16 LV-1 HV.
example

Gas turbines/Diesel generator
4 LV turbines to MV: Lower efficiency by 0.57% (so dont use 4 LV gas turbines instead of 1 MV gas turbine for efficiency purposes)
16 LV turbones to HV: Increased efficiency by 1.01% (more efficient but likely not worth the effort since you need 16 turbines instead of 1 and 5 transformers)
4 MV turbines to HV: Increased efficiency by 2.24% (Might be worth it if your fuel gathering is manual, however this is a fairly small saving.)
Steam turbines
4 LV steam turbines to MV: increased efficiency by 4.85%
16 LV steam turbones to HV: Increased efficiency by 10.8%
4 MV steam turbines to HV: Increased efficiency by 6.62%
Due to the larger difference in efficiency between different tiers of steam generators you will actually get a significantly higher net efficiency by using LV generators and transforming to higher voltage tiers. If you got space and dont mind the extra machines this is deffinetly worth it.
General observations:
Never forget that the net power output actually decreases when you transform the voltage up (due to the transmission losses). Similar things would happen when you transform down voltage from 1 amp of higher voltage to 4 amps of lower voltage with a small net decrease in power. For instance transforming down 1 amp of 8192 V down to LV you actually only get a total of 7232 eu worth of LV or 226 amps (instead of 256 amps)
LV-MV net output 124 eu/t
LV- HV net output 485 eu/t
MV-HV net output 504 eu/t
Transforming down voltage
IV to LV 87.94% net output 7232 eu/tick
IV to MV 94.16% net output 7744 eu/tick
IV to HV 97.28% net output 8000 eu/tick
IV to EV 98.83% net output 8128 eu/tick
IV 99.61% net output 8192 eu/tick (but consumes 8224 worth of fuel)
