The station has a number of step up transformers that allow connection to the GIS Substation.
2.
Also the old 285 MVA generator step up transformers were replaced with new 17kV / 345kV, 325 MVA transformers.
3.
So is it safer to put a step up transformer after the variac ? talk ) 23 : 46, 4 April 2015 ( UTC)
4.
The MW-5 used a step up transformer to raise the three phase input power ( at 240 volts ) to 17, 000 volts.
5.
Electrostatic speakers have their own problems due to the need for the membrane requiring high voltage, which is dangerous and has the requirement of a step up transformer, which is costly.
6.
If so, the step up transformers are just integer multiples of that . 11kV isn't magic, it's just that whatever votage is picked first, all subsequent voltages will probably be a multiple of that.
7.
In high school I hooked up an induction coil ( 19th century device which has a step up transformer to change 6 V DC to several thousand volts AC with an internal interruptor ), a 6 volt battery, and a swith, to build a spark radio transmitter.
8.
The resulting signal is only a few hundred microvolts, and thus more easily swamped by noise, induced hum, etc . Thus it is more challenging to design a preamplifier with the extremely low noise inputs needed for moving-coil cartridge, therefore a " step up transformer " is sometimes used instead.

The design output of Francis turbines is 41, 171 kW each, the turbine speed is 428.6 r . p . m ., the generator rating is 46 MVA, and generation voltage is 10.5 kV . An outdoor switch yard is provided next to the surface powerhouse with main two step up transformers of 50 MVA rating and voltage ratio is 10.5 / 240 kV . The powerhouse is operated both under the remote control mode from the south regional dispatching control and automatically under the local control mode.
