certain drawbacks. The conventional electrical substations require large space for
installation. In addition, the conventional electrical substations require huge
amount of installation cost. The conventional electrical substations have very low
power flow per unit area when compared to the space required for installation.

installation of the conventional electrical substations is not economical.
25  In light of the foregoing discussion, there exists a need for an electrical
substation which overcomes the above cited drawbacks of conventionally known
electrical substations.
