Increase in HT and LT Ratio

It is well known that for high HT/LT ratio, the losses will be low. The losses for a given quantum of power supplied through a line are inversely proportional to the square of its operating voltage. Higher the operating voltage, lower will be the line losses. Thus, by increasing the HT lines the losses will be decreased. Installation of lower capacity distribution transformers to serve a smaller number/cluster of consumers will result in increase in HT lines and decrease in the length of LT lines as HT lines will have to be taken nearer to the consumers. This will lead to reduction in losses.
