This question relates to the economic decisions that electricity utilities make in designing their power networks. During peak load periods, power is transmitted at the maximum current that is safe for the network, but at other times power transmission simply depends on demand.
Ideally, utilities would transmit power at maximum efficiency because, by minimising losses over the lines and in Transformers, they minimise generation costs. However, each increase in efficiency results in increased capital costs. A compromise is always made between purchasing efficient power Transformers and distribution transformers or less expensive ones with higher losses.

the efficiency is maximum in a transformer when no load loss is equal to load loss.
It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.
It is maximum at about 75% to 100% of the motor rated load. Efficiency is maximum at unity power factor , when R=X and when variable losses Is equal to constant losses at rated load.
The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss
Efficiency is typically calculated as the ratio of actual output to maximum possible output, expressed as a percentage. The formula for efficiency is: Efficiency = (Actual output / Maximum possible output) * 100%.

The maximum distance a wire can transmit a signal without significant loss in range is typically around 100 meters.
The optimal concentration of nm for achieving maximum efficiency in the experiment is 10 nanomolar (nm).
