I'm hoping to use this(CR8420-1000-G) current transformer to detect ground faults of 20mA. Using the formulae in the datasheet:
Here are my calculations:
For best linearity, choose R such that V < 0.8 VL
I'll go with 0.5:
Now say I'd like to have a 500mV output for 20mA:
35.3KOhm seems way out in left field for the burden resistor. I was expecting something around 500 Ohm.
Did I miss something?
