To account for the fact that voltage and current are not equal along the entire length of a long transmission line the so called distributed parameters must be used when calculating power transfer. These parameters are mostly depicted in the form of an equivalent 𝜋-circuit. This tool helps to figure out what power has to be fed in on the sending end of a transmission line if parameters of the line and all the quantities on the receiving end are given.
