I am looking at this current transformer.
What I am trying to understand is the following:
- Can the burden/load resistor of a current transformer take an arbitrary value? What are the limits?
- Does the secondary winding resistance have to be taken into account at some point?
In this answer to a similar question, the output voltage depends only on input current, turn ratio, and burden resistor.
I am assuming, this is a simplified formula. When will I breach its limits? Would it hold even if I substitute a 80ohm burden resistor for 1ohm or 100kOhm resistor and still get accurate answers?
How do I simulate a current transformer in LTspice to explore the behaviour further?
