Instrument transformers are small transformers used to measure the voltage or current on the grid or provide power to system monitoring devices.
Transformers at power plants boost the voltage before sending electricity on its way (usually in three separate lines, called phases), reducing the current, and thus minimizing energy wasted from the resistance of conductors.
You probably heard about the new keyboard which looks the same but should be way smarter with transformer based auto correct and improved dictation.
