The paper presents the procedure for finding out inductive compensation required for an EHV transmission line at its terminals. It also presents the design methodology for the power inductor. The 3-phase power inductor is similar in construction to a 3-phase core-type transformer with the exception that it has only one winding per phase and each limb is provided with an air-gap, the length of which is decided upon by the inductance required. Shunt compensation at the load end of a long transmission line for maintaining the load voltage at a fixed percentage of the sending-end voltage. Long-line model is used to determine the critical power that the line can transmit with and without series compensation.
