Re: how to use a current transformer
Original poster: coils-at-dslextreme-dot-com
Thanks for the responses,
So I need a resistor across the CT leads, soldered on preferably. Does
the value of this resistor establish the Volts and power at the CT leads?
2ohms -at- 100:5A = 10v, 50w
.2= 1v, 5w
.02= .1v, .5w
no resistor = dangerous 20x volts
I'm not clear on what value I should use to be safe and to properly load
the CT. Once I have a suitable resistor in place, can I read the output
with my handheld meter? Finally, at 100:5 A full scale, and I am
anticipating 30 amps through the CT (one pass), should I hope for 1.5 amps
at the CT leads?
