user38673: I'm new to electronics and need some help please.
I'm planning to measure current of a 3-phase output using one sensor for each phase (thus 3 sensors would be required). The frequency of data recording should be 200 Hz.
Performance/data transfer wise: Is one Arduino Uno board enough to plug in the three sensors and get the data transferred using the USB cable onto a PC? Or should I get one board for each sensor?
I appreciate your help.
Cheers.

user1576: 
Is the sampling speed enough?

It takes about 100 microseconds (0.0001 s) to read an analog input, so the maximum reading rate is about 10,000 times a second.

Is the USB port fast enough?

The serial speed over USB is maximum 2Mbps and a fast calculation (200 samples/s x 3 sensors x 10 bit) 18kbps, so 2Mbps should be enough.
