CT (current transformer) Burden is the maximum load that the CT secondary can drive (e.g. meters or protection relays)
Why do you care about burden when ordering current Transformers?
The burden is the termination impedance of the measuring instrument. The measuring instrument can be an analog or digital energy meter, a data logger or a recorder. All instruments that use a current transformer to measure line current must terminate the CT with a resistance (impedance in same case which means there is some inductance involved).
A CT supplier should be given the burden when ordering. Technically, the total burden for a CT is the internal winding resistance, the connecting lead resistance and the measuring instrument input resistance.
Some Ct's are installed a long distance from the measuring instrument and the connecting leads can have a resistance as much as 0.002 ohms per foot (both ways because the current makes a complete round trip). This resistance will cause an error if not taken into account.

What is shunt in electrical engineering?
In electrical engineering, shunt means 'parallel'.
Application of integration in electrical engineering?
use of integration in electrical engineering
What is the difference between electrical engineering and electrical power engineering and what bachelors degrees that will allow me to get a masters degree in mechatronics engineering?
Electrical engineering is low voltage, logic circuits, communications etc. Power engineering is electrical transmission and the like.You want EE.

Why should you study electrical engineering?
To understand and practice the Electrical engineering and finally become a good Electrical Engineer.
Can a CT drive more than 1 ammeter?
Yes, as long as the burden of these ammeters does not exceed the VA rating of the CT.
