Extra High Voltage substation. It generally 132 kv or higher

EHV - EXTRA HIGH VOLTAGE - STARTING 500 KILOVOLTS IN UP (500,000 VOLTS)

Hi, The main difference is Fuel consumption. High current genertors always consumes much fuel because the load on the engine will be high. The high voltage low current generators doesn't need much fuel to run. You can understand this by comparing 1 kva and 5 kva single phase generators. For both generators voltage will be same (230v) But output current differs. So the fuel consumption also differs. But you get a high current source. Low voltage high current generators can be used for welding kind of stuffs which needs high current to do the job. If you have step down transformer then you can save the fuel.

static electricity can be called high voltage static electricity can be called high voltage static electricity can bend water

EHV lines are type of electrical lines commonly used for experimentation in physics. They stand for 'Extra High Voltage' lines.
