The reason is that this is in the optimum range for power
supply on a national scale. The use of lower frequencies
would cause the size, weight and cost of the installed
equipment to increase and the flicker of lights to become
noticeable (as it was on early 25Hz systems). The use of
higher frequencies would cause increase in the operational
losses due to eddy currents, hysteresis, skin effect,
radiation etc. and reactive voltage drops.
