7. A portable electrical substation, comprising:
a rectangular platform having a top surface, the top surface having a geometric center between an upstream end and a downstream end and between a first side and a second side, wherein a longitudinal axis passes through the geometric center and along the top surface substantially parallel to the first side and the second side, wherein a lateral axis passes through the geometric center and along the top surface substantially parallel to the upstream end and the downstream end;
a primary high-voltage transformer attached to the top surface symmetrical about the longitudinal axis and symmetrical about the lateral axis;
AC voltage switchgear attached to the top surface upstream from the primary high-voltage transformer and substantially parallel to the lateral axis;
a pair of controlled rectifiers attached to the top surface downstream from the primary high-voltage transformer and aligned together substantially parallel to the lateral axis;
one or more lowpass filters attached to the top surface downstream from the pair of controlled rectifiers and symmetrical about the longitudinal axis; and
DC voltage switchgear attached to the top surface proximate the downstream end, substantially parallel to the lateral axis, and symmetrical about the longitudinal axis.
