Tomorrow's ehv transformers pose new shipping problems

The single 3-phase power transformer becomes harder to handle as it increases in bulk to match today's increasing generation outputs and transmission voltages. Only a technological break through can shift the practical, physical limits associated with accommodation to rising MVA ratings. It is quite likely that at voltages above 345 kV, the width requirements will establish the limit on transformer size, requiring either disassembly or a change to multiple smaller units. When the 750 kV transformer for the South Substation of Project EHV (General Electric) was transported over the highways, its weight had to be distributed over a large number of axles in accordance with local and state laws.
