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 the difference between relay burden and CT burden?
Relay burden refers to the amount of power consumed by a protective relay to operate correctly, primarily associated with the relay's input and output circuits. In contrast, CT (Current Transformer) burden is the load connected to the secondary side of a current transformer, typically expressed in ohms or VA, which affects the accuracy of the current measurement. While relay burden impacts the relay's performance, CT burden influences the transformer's ability to provide accurate current readings without saturation or distortion. Both are crucial for ensuring reliable functioning in electrical protection and measurement systems.

This is not understandable. Please rephrase and resubmit. Be specific
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.
