What is the effect of 30A Line Current close to PCB circuit
Hi All,
I'm designing a three phase power meter based on a ADE7758 and want to use PCB based Current Transformers (CT's) of 30A/30mA. This means there will be 3x30A caring line wires running cm-ers over the PCB trough the CT's. Its similar like the meter below but now with three phases. I'm worried about the induced noise on the PCB wiring by this 50/60 Hz magnetic field coming from the line wires. Is there any one who has experience on the sensitivity of using changing 50/60 Hz magnetic fields close to PCB traces. Does any one have suggestion show to shield this if needed .
Thanks so far
Regards Oscar
