IET Digital Library: IET Generation, Transmission ... ±800 kV UHVDC simulation system is established to verify the performance of the proposed protection. Simulation test results show that the proposed protection can accurately distinguish the internal fault from external fault in the whole fault period. The identification performance is not influenced by the fault location or fault resistance.

Electrical substation - Wikipedia substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

The Oil Drum | The Alternative Energy Matrixtheoildrum.com/node/8925Because the voltage is near the top of the acceptable envelope already, a small voltage rise, rather than the expected voltage drop, may drive a need for mitigation. My third go-to mitigation for this type of problem, after larger transformer and larger secondary conductor, is to use a tapped distribution transformer, tapped down a fixed 2.5%.
